Which test should I use to find the difference..(between dichotomous and cat barb with 5 levels) ask to choose caseses if greater or equal to 1. Need to run both parametric and non parametric

Answer 1

Chi-square test is the best solution for this problem. However, this test needs large sample size in each cell. So if equal or less than 20% of cells has expected count less than 5, you can use Chi-square test, if the percentage is greater than 20%, the sample size is low and you can use Fisher exact test. The percentage of cells is automatically calculated by statistical software and you do not need to manually calculate it.
