Question

Lara is calculating the standard deviation of a data set that has 8 values. She determines that the sum of the squared deviations is 184.
What is the standard deviation of the data set?

8.2

4.2

5.1

184

Answer 1

Answer:

its 5.13 I just took the test

Answer 2

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
