Problem H1

Solution  

For the allocation below, find and interpret the MAD, variance, and standard deviation.


Stop! Do the above problem before you proceed. Use the tip text to help you solve the problem if you get stuck.
You will need to find the mean first in order to calculate the deviation for each value in the set.   Close Tip

 

Problem H2

Solution  

For the allocation below, find and interpret the MAD, variance, and standard deviation. (Note that in this problem the mean is not a whole number, so there will be a fractional deviation for each value. To simplify your work, round off each calculation to one decimal place.) What do these calculations tell you about the data in this problem as compared to the data in Problem H1?
