Exercise

Visualizing response frequencies

In this exercise, we will use the likert package to derive summary counts and a visualization of the responses to the brand_rep dataset. This is a survey to measure consumer attitudes toward the reputation of a given brand. All variables must be coded as factors in likert.

The likert and dplyr packages have been loaded.

Instructions

100 XP

Select all Likert-style items from brand_rep and convert them to factors, storing the results of b_rep_likert.
Pass the results of b_rep_likert to the summary() function to print response frequencies.
Plot the response frequencies for all items in b_rep_likert.
