2. When you get your output, click "Case Processing Summary" and delete with control-x (Edit/Cut); also Click "Crosstabs" and delete. THESE JUST CLUTTER YOUR OUTPUT AND I DO NOT WANT TO SEE THEM IN YOUR PAPERS. The validity rate reported under this summary is merely the percentage of case coded. Pay no further attention to it!
2. Percentaging is not required, but may be useful. If you percentage by rows, you can compare increasing or decreasing percentages in the columns. If you percentage by columns, you can compare increasing or decreasing percentages in the rows. NEVER PERCENTAGE BY TOTAL or BY BOTH ROWS AND COLUMNS: make up your mind which makes more sense, or percentages by the variables that has more categories.
2. ALWAYS click Options at this point and unclick "Display groups defined by missing values"
3. Remember to ALSO RUN crosstabs for this pair of variables and include the statistics boxes with the graph.
2. When you get your output, click "Case Processing Summary" and delete with control-x (Edit/Cut); also Click "Correlations" and delete. THESE JUST CLUTTER YOUR OUTPUT AND I DO NOT WANT TO SEE THEM IN YOUR PAPERS.
3. Typically you only need one correlation table (prefereably tau-c) in your paper and you might choose to skip the correlation table altogether. Alternatively, you might have one such table to show the reliability of each set of variables. Or you might present a correlation table for all of the variables with significant LINEAR relationships.
4. If variable numbers are not printed on your correlation table, make sure you write them in.
5. Beware variables with small sample sizes! Note how they lower the significance of correlations: and their correlations suffer random fluctuations. If you are using variables in the range 481-528, for example, look at the codebook and use only the average scores for boys and girls, which have overwhelmingly larger sample sizes.
2. Always try to fit UNBROKEN tables onto a single page for printing: that is, if your table is too long for 8.5" margins, it will break into two parts, and you should use LANDSCAPE printing instead.
2. Use replication by region (variable 200) only for testing replication of your major finding(s).
