Determine the standard variation of the data below. (1, 2, 3, 4, 5)
2 answers:
Calculate for the mean/ average of the given numbers: μ = (1 + 2 + 3 + 4 + 5) / 5 = 3 Then, we calculate for the summation of the squares of differences of these numbers from the mean, S S = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)² S = 10 Divide this summation by the number of items and take the square root of the result to get the standard deviation. SD = sqrt (10 / 5) = sqrt 2 SD = 1.41 Thus, the standard deviation of the given is equal to 1.41.
Answer:
So basically sqrt of 2...
