What is the denominator in the calculation of population standard deviation for a data set with items?
What is the denominator in the calculation of sample standard deviation for a data set with items?
In general, what does a larger value of σ mean?
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?
The data set shown contains a potentially outlying value of 32. What effect would removing this value have on the calculation of the standard deviation?
