Consider the following data: −10, −10, 0, 3, −10, 3, 3 Step 1 of 3: Calculate the value of the sample Variance. Round your answer to one decimal place. Step 2 of 3: Calculate the value of the sample deviation. Round your answer to one decimal place. Step 3 of 3: Calculate the value of the range.
Step 3 In order to use the defining formula for sample standard deviation, it is helpful to first calculate (x – x)² for each data value in the data set 1, 6, 7, 8, 9. Use the values in the data set and the previously determined mean, x = 6.2, to complete the following table. 7 8 6.2 6.2 6.2 6.2 6.2 х — х -5.2 0.8 2.8 (x – x)² 27.04 0.04 3.24 Submit Skip (you cannot come back)
