Numerical summaries of age

Let's continue our exploratory data analysis of the numerical explanatory variable age by computing summary statistics. Summary statistics take many values and summarize them with a single value. Let's compute three such values using dplyr data wrangling: mean (AKA the average), the median (the middle value), and the standard deviation (a measure of spread/variation).
