To find the standard deviation, you need to follow these steps:
1) Find the mean
2) Find the difference between each number of passenger and the mean = (no. of passengers - mean)
3) Then square the difference = (no. of passengers - mean)^2
4) Find the variance, which is the mean of (no. of passengers - mean)^2
5) Square root the variance to find the standard deviation
