# Visualizing the response variable

"How does stream velocity influence the feeding behavior of dragonflies?"

It is helpful if you have a general idea of the underlying structure of your response variable as you enter the modeling process. Now that you have identified `feeding_events`

as the response variable, use a histogram to look at the observed values for this variable.

A histogram will plot the frequency that each value of `x`

can be found in the data.

Note that the `dragonflies`

data set and `ggplot2`

library have been preloaded.
