Data set 1:0, 0, 0, 100, 100, 100

Data set 2:0, 20, 40, 60, 80, 100

Data set 3:0, 40, 45, 55, 60, 100

all three data sets have a mean of 50. how spread out the points are in each data set and compare this to the standard deviations for the data sets. what is the relationship between the amount of spread and the size of the standard deviation and explain why this connection exists. not give calculations I need to answer in sentence form.
