Exercise

# Descriptive statistics

This exercise will cover how to get simple descriptive statistics for individual variables from the `abalone`

dataset and for multiple variables at once. You will use the functions `pull()`

, `mean()`

and `median()`

for single variables and `select()`

and `summary()`

to get summary statistics on multiple variables at once.

The `abalone`

dataset and `dplyr`

package are already loaded for you.

Instructions

**100 XP**

- Find the mean length of the abalones using both the
`pull()`

and`mean()`

functions. - Find the median whole weight of the abalones using both the
`pull()`

and`median()`

functions. - Get summary statistics of diameter and shell weight using the
`select()`

and`summary()`

functions.
