The jitter plot is pretty clear to see the difference between different modes.
The interpretation of each plot is clear and easy to understand.
Constructive
It will better to explain more about the variable "Arrival Time". What does "-50" and "50" mean for "Arrival Time"?
Why some plots use "MW arrival time" while some plots use "All days arrival time"? In the second plot, it does not specify which arrival time on the plot.
Since the survey question is about the relationship between arrival time and distance, I don't see a reason to test if there is a significant difference of the arrival time between MW and TT.
Suggestion for milestone 3:
To provide plot and test for X and Y (distance and all days arrival time)
To provide distribution plots of explanatory variables.
