Setting up axes for T statistics

For all tests except the paired preference test, each column element to be tested must have an ID. For the paired preference test each row element to be tested requires an ID. IDs are single upper case letters assigned with id=. You are therefore restricted to testing 26 columns (rows for the Paired Preference Test), because there are 26 letters in the alphabet. Quantum prints the identifiers with the element texts and uses them in the rows or columns to mark elements which differ significantly from the other elements in the test. In addition, when the elements form the columns of a table, Quantum generates an extra line of column headings showing the element IDs for each column.

Note If you are only using one confidence level, you can use lower case IDs as well as upper case IDs. This increases the maximum number of columns (rows for the Paired Preference Test) you can test to 52.

All row axes in tables to be tested must have a base element. Although the base itself is not normally tested, the figures from the base are used to determine whether there are sufficient respondents in the element for the test to produce valid results. The base figures are also used in the calculations of some of the statistics.
