What is the denominator in the calculation of population standard deviation for a data set with items?
Calculate, to the nearest hundredth, the sample standard deviation for each of the shown data sets.
|Data Set 1||25||22||28||51||26||28||29||32|
|Data Set 2||21||27||19||26||24||23||28||25|
Which of these statements helps explain the large difference between the sample standard deviations for the two data sets?
Without calculating the exact standard deviations of the following data sets, determine which of them has the lowest standard deviation.
