Exercise

Mean vs. median

In the video, you learned that the mean is the sum of all the data points divided by the total number of data points, and the median is the middle value of the dataset where 50% of the data is less than the median, and 50% of the data is greater than the median. In this exercise, you'll compare these two measures of center.

dplyr and ggplot2 are loaded and food_consumption is available.
