This is a easy chi-square calculator for a contingency table that has up to five rows and five columns (for
alternative chi-square calculators, see the column to your right). The calculation takes three steps,
allowing you to see how the chi-square statistic is calculated.
The first stage is to enter group and category names in the textboxes below. This calculator allows up to
five groups and categories, but fewer is fine. Please note, for anything larger than a 2 x 2 calculation,
you
need to specify your groups and categories by typing in the textboxes. "Group 3", "Category 3", and so on,
are just
placeholders.
Imagine, for example, that you have collected data on different teaching techniques for PhD candidates -
some have had no teaching, some have been taught, and some have been taught, plus they've sat yearly
exams - and you want to see whether these different experiences have an effect on the final result,
where the four possibilities are outright failure, a lower MPhil qualification, a deferral and a pass.
In this situation, the groups would be No Teaching, Teaching, Teaching + Exams (entered into the first
three boxes in the far left column); and the categories would be Fail, MPhil, Deferral and Pass (entered
into the first four boxes - left to right - of the top row).
