Question

Identify, describe and test the assumptions related to the Chi-Square technique

Answer 1

Below are the following assumptions:-

Chi Square techniques assume that the data were obtained through random selection.

The data in the cells should be frequencies, or counts instead of percentages or some other transformation of the data.

The variables which are being examined can be measured at any level, nominal, ordinal, interval, or ratio. The levels (or categories) of the variables are mutually exclusive.

Assumptions about expected value. No expected value should be less than 1 and no more than 20% of the cells should have less than 5 expected cases.
