Remember that a chi-square test is used to help determine if observed results are in line with expected results, and to rule out that observations are due to chance. This means that a chi-square statistic is a test that measures how a model compares to actual observed data.
The data used in calculating a chi-square statistic must be:
1. random
2. raw
3. mutually exclusive
4. drawn from independent variables,
5. and drawn from a large enough sample.
We can conclude that the correct answer is:
Answer:TRUE
