Ratio
What makes nominal data different from other levels of measurement?
It is always measured in numbers.
It includes both positive and negative values.
It measures both order and distance between values
It only indicates categories without any inherent order.

What is the purpose of the Chi-square test of association?
To compare the means of two populations
To evaluate the linear correlation between variables
To determine if a sample matches a known distribution
To test if there is a relationship between two categorical variables
What is the purpose of the Chi-square goodness of fit test?
To compare the means of two independent samples
To determine if observed frequencies differ from expected frequencies
To test for relationships between two categorical variables
To analyze differences between population variances
What assumption must be met for both the Chi-square goodness of fit and Chi-square test of association?
The data must be ordinal
The sample data must be normally distributed
The observations must be independent
