Question 588912
You are examining two sets of data. 
Set A has a mean (M) of 56 and a standard deviation (SD) of 5.3; 
Set B has a mean of 56 and a SD of 10.2. 
Assuming a “normal” curve, which of the data sets would you expect to have a more “extreme” range of data? 
Why? 
The standard deviation measures the spread of the data.
Set B has the larger std so has the greater range of data.
