To find the standard deviation, first, calculate the mean of the given data. Then, use the formula for variance ($\sigma^2 = \frac{\sum (x_i - \mu)^2}{N}$), where $x_i$ are the data points, $\mu$ is the mean, and $N$ is the number of data points. Finally, take the square root of the variance to find the standard deviation. The correct calculation leads to a standard deviation of approximately $114.2.
