Computing the Sample Standard Deviation with R

## Description

The following R command calculates the sample standard deviation of Babe Ruth's career homers for each season that he played in major league baseball. The sample standard deviation is defined as

(1)\begin{align} \sqrt{\frac{\sum\limits_{i=1}^{n} (x_i - \bar{x})^2}{n-1}}. \end{align}

To use R in a Sage cell, the language must be set to R. See https://github.com/sagemath/sagecell/blob/master/doc/embedding.rst for details.

## Sage Cell

#### Code

```
ruth <- c(22, 25, 34, 35, 41, 41, 46, 46, 46, 47, 49, 54, 54, 59, 60)
sd(ruth)
```
