How To Write a (Thesis / Dissertation) Proposal


1. Know the area
a. Read, read, read, …
b. Average 10-15 papers per week
c. Current Journals: at least read/scan abstracts
d. Use reference management software! (e.g. ProCite and EndNote)
e. Use search engines (MedLine, Ergo Abstracts, Psych Info, Compendex, ACM Digital Library, etc.)
f. Go to the source literature (don’t expect textbooks and other secondary sources to be either accurate or complete)
2. Go outside your area
a. Good source of new/different ideas
b. Avoids embarrassing overlap (already done by others in another field)
3. Pay attention to methods, analyses, motivations, applications
a. We did this because …
b. This work can be applied to …
4. Tree-in; tree-out
a. Look at paper citations, and who cited particular papers (ISI Citation Index)
b. Note how others interpreted (or how cited) papers you’ve already read; they may have a different interpretation
5. Don’t get ‘paper-locked’
a. Easy to get overwhelmed and biased by what has already been done
b. Once familiar with an area, what has and hasn’t been done, start working on what you could do
6. Look at proposals and documents generated by your predecessors

At this point, generate some initial ideas. Be creative, flexible, novel. Good idea to test them, if possible.

The proposal itself:
Be professional. Dress appropriately (even if faculty don’t!).
Should you bring refreshments? It’s certainly appreciated but definitely not needed or expected.

Jumping ahead, what does a faculty member look for in a proposal?
My opinions here, so don’t blame me!
Most, though, see it as a “contract”: “If you do this work, do it well and write it up well, we won’t later claim that it’s not appropriate or sufficient”

1. It should be well-written
a. Organized, with a logical flow
b. Concise, but also complete
c. Good grammar
d. It’s usually a good idea to have a colleague read it before giving it to the advisor, especially if they have already submitted their first draft or successfully defended their proposal. Often little errors or small changes will be identified and addressed. They can also be some the best sources of information for “why” or “how”.
2. General structure is typically followed, but there is flexibility in the details
a. Introduction (Background, Motivations, Literature review)
b. Objective/Purposes/Hypothesis (need not be a separate section, but often is)
c. Methods
d. Preliminary Results
3. Introduction
a. It’s not a literature review! It should be a summary of existing evidence that motivates your specific, proposed work.
b. Start broad (e.g. injuries, need for ergonomics, etc.), become increasingly specific
c. End with a review, and broaden out to discuss potential applications (importance) of the proposed work
d. Topics to be addressed: what’s been done; what hasn’t; what is needed and why; indicate your part or contribution (scoping your domain)
e. Intro should contain some statements of objectives, purposes, and hypothesis. Placement is flexible, though, and these could be in separate sections between Intro and Methods, or even part of the Methods. Depending on the specifics, not all of these (objective, purposes, and hypotheses) will always been relevant. More important that it be clear and readable.
f. How long should it be? Long enough to satisfy the above goals. Typically 10-30 pages for an MS, longer for a PhD proposal.
g. When summarizing existing literature, it is not enough just to describe what authors X, Y, and Z did. Results should be interpreted, in the context of the overall review and study objectives.
h. In particular, discuss contrasting evidence, possible sources for discrepancies (experimental design, lack of controls, sensitivity of measures, etc.), and the importance of resolving the differences.
i. Summarize evidence, rarely individual studies.
4. Objectives/Purposes
a. Non-quantitative, but specific and clearly filling some hole/need addressed in the Introduction.
b. The Intro should have motivated and “scoped” the stated objectives and purposes.
5. Hypotheses
a. Non-quantitative, but again specific and clear.
b. There should be obvious connections to the objectives; addressing (proving) your hypotheses supports achieving your objectives
c. There must be clear (though not stated here) indications of how statistical methods would be used to evaluate the hypotheses. In the methods, your statistical tests should make reference to these hypotheses.
d. Not every statistical test should have an associated hypothesis (otherwise it would be unwieldy); instead, the hypotheses can be general (e.g. there will be an association among several variables; factors A and B will have effects on several measures of performance).
e. Don’t use words like ‘significant’, save this for the description of statistical methods.
6. Methods
a. What will be done, how, and why? In particularly “why” (why this IV, why these levels, why this measure, …)
b. With respect to how and why, there is typically more than one way to do
something, and you must explain (and sometimes justify) your choice.
c. The methods should have clear connections to the hypotheses.
d. The Methods tends to be a difficult and sometimes complicated section. In general, proceed from broad to specific, but also ensure that a context is provided before specific details are raised. For example, don’t describe specific experimental treatments before you’ve even explained the overall approach and the different independent and dependent variables.
e. For widely-used and generally accepted approaches, just summarize with reference to the literature. For other approaches, more explanation and justification needed.
f. Note that ‘repeated measures’ refers to a study design, while within- and between-subjects refers to specific independent measures (or treatments). Nested and between-subjects factors are synonymous.
g. The reader should be able to understand what you’re talking about, given what was provided before (use of a colleague again helps here).
h. Subsections are often used such as: Overview; Participants; Procedures; Instrumentation; Experimental Design; Data Reduction; Analysis (stats)
i. The specific ordering of the sections in g., should achieve the goals of d. and f.
j. Somewhere (typically in Experimental Design), there should be an explicit statement of the independent and dependent variables (or factors, or measures)
7. Limitations, expected results, contribution, future work (don’t leave the reader to guess these)

So how do I get there? Unfortunately, this is as much an art as a science, but here are some things to consider:

1. Some General Tips:
a. Each paragraph proceeds from general to specific.
b. Some have suggested that reading the first sentence of every paragraph in the document should convey the essential meaning of the whole.
c. Vary the structure of your sentences and paragraphs.
d. Use transitions between paragraphs (either the last sentence of the proceeding one or the first sentence of the subsequent one, should tie the two together).
e. Avoid one-sentence paragraphs (generally at least 3 sentences comprise a paragraph)
f. Consider optional presentation methods (always using good HF knowledge and practice). Often the same thing can be conveyed by text, graphs, tables, diagrams, etc. Pick what is the most effective, but avoid duplication.
g. Get in the habit of writing (and reading, in a special way, as noted earlier). As a student, it helped me to write something every day, even if it was brief, and even if I didn’t later use it. It also helped (and still does) to write down my thoughts.
2. Some common mistakes to avoid:
a. Repetitive sentence structure (The… The… The… or However, … Additionally, … Therefore, …)
b. Avoid complex words and convoluted sentence constructions, where simpler ones will convey the information (like utilize vs. use; cognizant vs. aware; though personal style always has a role). Eschew obfuscation!
c. There is no advantage to be gained by making something obscure. The scientific value is not enhanced by complicated words and prose, and to someone that knows the field, you don’t sound any more knowledgeable. If you look at some of the best journals, they are typically written in a very dry, boring, direct, and terse style. It tends to be the weaker journals where creative writing flourishes!

VECTORS AND LOOPS


Vectors and loops are two tools drawn from computer programming that can be very useful when manipulating data. Their primary use is to perform a large number of similar computations using a relatively small program. Some of the more complicated types of data manipulation can only reasonably be done using vectors and loops.

A vector is a set of variables that are linked together because they represent similar things. The purpose of the vector is to provide a single name that can be used to access any of the entire set of variables. A loop is used to tell the computer to perform a set of procedures a specified number of times. Often times we need to perform the same transformation on a large number of variables. By using a loop, we only need to define the transformation once, and can then tell the computer to do the same thing to all the variables using a loop.

If you have computer-programming experience then you have likely come across these ideas before. However, what SPSS calls a “vector” is typically referred to as an “array” in most programming languages. If you are familiar with arrays and loops from a computer programming course, you are a step ahead. Vectors and loops are used in data manipulation in more or less the same way that arrays and loops are used in standard computer programming.

Vectors
Vectors can only be defined and used in syntax. Before you can use a vector you first need to define it. You must specify the name of the vector and list what variables are associated with it. Variables referenced by a vector are called “elements” of that vector. You declare a vector using the following syntax.

vector Vname = varX1 to varX2.

If the variables in the vector have not already been declared, you can do so as part of the vector statement. For more information on this, see page 904 of the
SPSS Base SyntaxReference Guide. The following are all acceptable vector declarations.

vector V = v1 to v8.
vector Myvector = entry01 to entry64.
vector Grade = grade1 to grade12.
vector Income = in1992 to in2000.

The vector is given the name Vname and is used to reference a set of variables defined by the variable list. The elements in the vector must be declared using the syntax first variable to last variable. You cannot list them out individually. This means that the variables to be included in a vector must all be grouped together in your data set.

Vectors can be used in transformation statements just like variables. However, the vector itself isn’t able to hold values. Instead, the vector acts as a mediator between your statement and the variables it references. The variables included in a vector are placed in a specific order, determined by the declaration statement. So if you give SPSS a vector and an order number (referred to as the index), it knows what specific element you want to access. You do not need to know what the exact name of the variable is - you just need to know its location in the vector.
References to items within a vector are typically made using the format

vname (index)

where vname is the name of the vector, and index is the numerical position of the desired element. Using this format, you can use a vector to reference a variable in any place that you would normally insert a variable name. For example, all of the following would be valid SPSS statements, assuming that we had defined the four variables above.

compute V(4) = 6.
if (Myvector(30)='house') correct = correct + 1.
compute sum1 = Grade(1) + Grade(2) + Grade(3).
compute change = Income(9) - Income(1).

Note that the index used by a vector only takes into account the position of elements in the vector - not the names of the variables. To reference the variable in1993 from in the Income vector above, you would use the phrase income(2), not income(1993).

Using vectors this way doesn’t provide us with much of an advantage - we are not really saving ourselves any effort by referring to a particular variable as Myvector(1) instead of entry01. The advantage comes in with the fact that the index of the vector itself can be a variable. In this case, the element that the vector will reference will depend on the value of the index variable. So the exact variable that is changed by the statement

compute Grade(t) = Grade(t) + 1.

depends on the value of t when this statement is executed. If t has the value of 1, then the variable grade1 will be incremented by 1. If t has a value of 8, then the variable grade8 will be incremented by 1. This means that the same statement can be used to perform many different things, simply depending what value you assign to t. This allows you to use vectors to write “generic” sections of code, where you control exactly what the code does by assigning different
values to the index variables.

Loops
Vectors are most useful when they are combined with loops. A loop is a statement that lets you tell the computer to perform a set of commands a specified number of times. In SPSS you can tell the computer to perform a loop by using the following code:

loop loop_variable = lower_limit to upper_limit.
--commands to be repeated appear here--
end loop.

When SPSS encounters a loop statement, what it does first is set the value of the loop variable to be equal to the lower limit. It then performs all of the commands inside the loop until it reaches the end loop statement. At that point the computer adds 1 to the loop variable, and then compares it to the upper limit. If the new value of the loop variable is less than or equal to the upper limit, it goes back to the beginning of the loop and goes through all of the commands again. If the new value is greater than the upper limit, the computer then moves to the statement after the end loop statement. Basically, this means that the computer performs the statements inside the loop a total number of times equal to (upper limit - lower limit + 1).
The following is an example of an SPSS program that uses a loop to calculate a sum:

compute x = 0.
loop #t = 4 to 8.
+ compute x = x + #t.
end loop.

The first line simply initializes the variable count to the value of zero. The second line defines the conditions of the loop. The loop variable is named t, and starts with a value of 4. The loop cycles until the value of t is greater than 8. This causes the program to perform a total of 5 cycles. During each cycle the current value of t is added to x. At the end of this set of statements, the variable x would have the value of 4 + 5 + 6 + 7 + 8 = 30.

In this example, the loop variable is denoted as a .scratch variable. because its first letter is a number sign (#). When something is denoted as a scratch variable in SPSS it is not saved in the final data set. Typically we are not interested in storing the values of our loop variables, so it is common practice to denote them as scratch variables. For more information on scratch variables see page 32 of the SPSS Base Syntax Reference Guide.

You will also notice the plus sign (+) placed before the compute statement in line 3. SPSS needs you to start all new commands in the first column of each line. Here we wish to indent the command to indicate that it is part of the loop. We therefore put the plus symbol in the first column which tells SPSS that the actual command starts later on the line.

Just in case you were wondering, the first statement setting x = 0 is actually necessary for the sum to be calculated. Most programming languages, including SPSS syntax, start variables with missing values. Adding anything to a missing value produces a missing value, so we must explicitly start the variable count at zero to be able to obtain the sum.

The Power of Combining Vectors and Loops
Though you can work with vectors and loops alone, they were truly designed to be used together. A combination of vectors and loops can save you incredible amounts of time when performing certain types of repetitive transformations. Consider the characteristics of vectors and loops. A vector lets you reference a set of related variables using a single name and an index. The index can be a variable or a mathematical expression involving one or more variables. A loop repeatedly performs a set of commands, incrementing a loop variable after each cycle. What would happen if a statement inside of a loop referenced a vector using the loop variable as the index? During each cycle, the loop variable increases by 1. So during each cycle, the vector would refer to a different variable. If you correctly design the upper and lower limits of your loop, you could use a loop to perform a transformation on every element of a vector.

For an example, let’s say that you conducted a reaction-time study where research participants observed strings of letters on the screen and judged whether they composed a real word or not. In your study, you had a total of 200 trials in several experimental conditions. You want to analyze your data with an ANOVA to see if the reaction time varies by condition, but you find that the
data has a right skew (which is common). To use ANOVA, you will need to transform the data so that it has a normal distribution, which involves taking the logarithm of the response time on each trial. In terms of your data set, what you need is a set of 200 new variables whose values are equal to the logarithms of the 200 response time variables. Without using vectors or loops, you would need to write 200 individual transformation statements to create each log variable from the corresponding response time variable. Using vectors and loops, however, we can do the same work with the following simple program. The program assumes that the original response time variables are rt001 to rt200, and the desired log variables will be lrt001 to lrt200.

vector Rtvector = rt001 to rt200.
vector Lvector = lrt001 to lrt200.
loop #item = 1 to 200.
+ compute Lvector(#item) = log(Rtvector(#item)).
end loop.

The first two statements set up a pair of vectors, one to represent the original response time variables and one to represent the transformed variables. The third statement creates a loop with 200 cycles. Each cycle of the loop corresponds to a trial in the experiment. The fourth line actually performs the desired transformation. During each cycle it takes one variable from Lvector and sets it equal to the log of the corresponding variable in Rtvector. The fifth
line simply ends the loop. By the time this program completes, it will have created 200 new variables holding the log values that you desire.

In addition to greatly reducing the number of programming lines, there are other advantages to performing transformations using vectors and loops. If you need to make a change to the transformation you only need to change a single statement. If you write separate transformations for each variable, you must change every single statement anytime you want to change the specifics of the transformation. It is also much easier to read programs that use loops than programs with large numbers of transformation statements. The loops naturally group together transformations that are all of the same type, whereas with a list you must examine each individual transformation to find out what it does.
