 The previous videos tested gender differences in height and number of shoes, both of which are interval data. That's why we used a t-test. Now let's test if there is a gender difference in response to the item. Everyone should have a pet at least once in their lifetime. Since that's a Likert scale item, it's not interval. It's ordinal. So you need to use the Mann-Whitney-U test. Configure the test. And as before, make sure that you have the correct table chosen. And then choose the dependent variable, pet, on the left. This time it's called ranked, not average, because the variable is ordinal. At the right, choose the variable used for comparison, gender, and the two groups, female and male, and show the results. In this case there is no significant difference in men and women's opinion on this item. And again, you will notice that the results show you the median, not the average, and in this case the medians are identical.
