I have some data in which there are 5 categorical explanatory variables (
concern, breath, weath, sleep, act) and 1 continuous response variable (
tto). In addition, every categorical explanatory variable is divided into 5 levels which show how strong a person feels about it. level 1 and level 5 show the perfect and worst states respectively.
I was advised to create a box plot to see the relationship between the explanatory variables and the response variable. The plot is given below. However, I do not know how to read a box plot. Can any one please help me interpret it.
