Answer #1

The chi-square test for independence requires count data.

Note :

The assumptions about the data in Chi-square test of independence:

1) The level of measurement of all the variables is nominal or ordinal.

2) The distribution of the data was seriously skewed or kurtotic (parametric tests assume approximately normal distribution of the dependent variable), and thus the researcher must use a distribution free statistic rather than a parametric statistic.

3) The data in the cells should be frequencies, or counts of cases rather than percentages or some other transformation of the data.

One of the requirements of a chi-square test is independence - subjects cannot fit in more than one category. This is because of the way the chi-square analysis is set up, as you are looking at predicted and expected ratios. There's another requirement in that categories must be exhaustive - everyone must fit into one of the categories. This is done for the same reason. Do you feel that this is a weakness of chi-square analyses? It's often argued that...
