I was unable to understand how to compare multiple mean values in each group. Within the subgroup the mean values influence each other (If one changes, the other changes automatically).
I collected travel distance and the mode of transportation choice at two different locations. There are 32 people in each location with "x" different modes. A person can choose one mode and record their travel distance.
How should I compare to see if the travel distances traveled by different modes of these two groups are significantly different? If it is categorical data, I know I have to use chi square, but does the t-test work here? I believe the t-test is to compare two groups with one mean in each group. But I have 2x separate mean values (one for the each mode and two locations).
