UPCOMING WEBINAR: 10 Market Research Predictions Over the Next 4 Years Although there is a relatively large overlap between the statistical tests in SPSS Statistics and Displayr, very few of the default tests in Displayr match the default tests available in SPSS.
Requirements
A Displayr document with at least one table or visualization
Method
If seeking to compare test outputs between the programs, the following needs to be kept in mind:
- In Displayr, test selection is usually done by changing the data setup, rather than by selecting specific tests (see Tests of Statistical Significance).
- Most statistical tests in SPSS assume that either the data is unweighted, or, that any weights are frequency weights. Displayr, by contrast, assumes that weights are sampling weights. See Using Frequency Weights in Displayr for instructions for making Displayr treat the weights as frequency weights.
- The rule named Significance Testing in Tables - Independent Samples Column Means and Proportions Tests has been designed to replicate some commonly used SPSS tests.
