Original Question:

1. Your overall research question;     2. The research hypothesis and null hypothesis

Special note:

When a variable is continuous (interval/ratio level of measurement), for example, age of respondent, we do not run crosstab directly b/c it will result in a really spread-out table with lot of 0s and low frequency cells. Such crosstab does not help us understand the data.

The correct way is to reduce the level of measurement to either ordinal level or nominal level and then run the cross table. The way to fix is to reduce I/R level of measurement to a lower level by lumping columns in into just a few categories. For example, you can group age 19 to 22 as one category, 23 to 30 as one category, and so on.  In this way, your crosstab will help us better understand data. Here is an example of recoding: https://www.youtube.com/watch?v=uzQ_522F2SM

Interpreting crosstab output

When you interpret the result, please include the discussion of epsilons (p. 170) and the 10% rule (p. 165). The epsilons in short is the differences between the highest and lowest column % in any given row.  As long as one epsilon makes the 10% threshold, we’ll deem two variables have “enough” going on to with each other to warrant further statistical analysis.
