Marginals: Tabulating Data Online

The marginals program lets you run simple frequency tabulations of the data in real-time by browsing to and logging into the Online Administrative Module. You can analyze complete and/or incomplete records.

Select the Question

This combo box lets you select which question to tabulate. You can only tabulate results for one question at a time.

Respondent Status

Here you specify whether you want to tabulate results for All Respondents, Qualified/Completes Only, Incomplete, or Disqualified.

Click Show Report to run the marginal report. You can print the results of any marginals run by clicking the Print icon in your browser, or choosing File | Print.

Marginals for Numeric/Single Select Questions

Marginals reports for Numeric and Single select questions are quite similar, since each question contains a single response. Here is an example for the question gender, for just four respondents:


The Value column shows the values that were recorded in the data. The Label column displays the label used for each response category (if applicable). Count shows how many respondents used each unique value. Percent shows a bar graph with percentage of respondents (who answered the question) that used each value. Finally, the N (total number of respondents that answered the question), Min (minimum value used), Max (maximum value used), Mean (average of values used), and Missing (number of respondents who saw the question and submitted the corresponding page, but did not provide a response to this question.) Note that missing data do not factor into the N, Min, Max, and Mean computations.

Marginals for Multiple Select Questions

Consider the following question:


The marginals report for this question may look like:


With select-type questions, a Label column appears to show the text associated with each value for this question. The Count column shows that a total of 3 + 5 + 4 + 5 = 17 responses were provided by the 10 respondents who received this question. The percents are percents of respondents (30% of respondents said they use their laptops at home) rather than percents based on total responses given. As a result, the percents will not usually sum to 100%.

Please note that all respondents who saw this question and submitted the corresponding page are counted in the base for multiple response questions, even if they did not check any of the boxes. Therefore, no Missing category is reported.

Notes:

Grid Questions: Multiple-response check-box questions within grids are available for tabulation. The variable for a row-based question is listed using the convention grid_r1_c* where the asterisk means that check boxes across all columns for the question in row1 will be tabulated. The convention for column-based questions is grid_r*_c1 where the asterisk means that check boxes across all rows for the question in column1 will be tabulated.
