Significance Testing for Overlapping & Independent Samples

This article gives more information on the situations in which overlapping samples can be sig tested in askiaanalyse. This KB article explains the correct tests to use when testing for significance in independent or overlapping samples.

Significance testing diagram

If you are sig testing columns and it’s the case that a respondent belongs to more than one column (e.g. in a multi-coded question or loop summary table) then the most statistically accurate tests to use are the paired tests. Otherwise, it’s the independent tests.

Check out the knowledge base article for the detailed version.

Clean up your askiafield environment

As with many server applications, we, as users, tend to let our askiafield server environment clutter with files, leftover metadata other useless tidbits. These can slow down the host environment and even impact production performance.
We have added a complete guide to get rid of this unused data, free up some space on your askiafield server.

From freeing up memory to speed up application responsiveness to backing up your SQL data and askiafield data to save storage space.

Programming Column Significance

This 3-part article details the use of Student Test column significance calculations in askiaanalyse. Each part of this article concentrates on specific aspect of these calculations:

1. Classical Student Test

This article demonstrates a scenario in which which we would need to script the formula for Classical student test on closed question. It shows the formula and gives two examples on how to program it with a few tips on how to refine the syntax and mirror settings in the pre-set col sig calculation.

2. Student test using estimator

This article demonstrates how to script the formula for Student Test using estimator on closed questions. Formula and syntax are shown along with tips on how to mirror particular settings in the pre-set col sig calculation.

3. Student test using efficiency coefficient

This article demonstrates how to script the formula for Student Test using efficiency coefficient on closed questions. Formula and syntax are shown. There is also a demonstration of calculating Effective base manually.
