I will attach the formula for the standard deviation.

N = 8
sum of the squared deviations is 184.

standard deviations = square root of 1/N * sum of squared deviation
standard deviation = √(1/8 * 184)
standard deviation = √23
standard deviation = 4.80

The standard deviation of the data set is 4.80
