Answer:
169
Step-by-step explanation:
The variance is equal to the square of the standard deviation
To get the variance of the data, we have to square the standard deviation 13^2 = 169.
To square a number we have to multiply it by itself:
13^2 = 13* 13 = 169
The standard deviation is a statistical value that measures how much variation or deviation there is in a set of values; the lowest deviation indicates we have values closer to the mean, and a bigger deviation indicates that we have values that vary a lot from the mean.
The variance is a statistical value that measures how far are a set of values from the average, and it is the square of the standard deviation.
