Deviation Compare 1

The document contains 3 problems about calculating and comparing mean absolute deviations of data sets. For problem 1, the mean absolute deviation of data set A is 19.43 and of data set B is 15.71. For problem 2, the mean absolute deviation of team A's scores is 4.33 and team B's is 22. For problem 3, the mean absolute deviation of the prizes won is 21.14 with the value 65 and 20.67 without it, so removing 65 makes the data closer to the mean.

3) The table below shows the number of prizes won by the students of seven schools in an
interschool competition. Find the mean absolute deviation of the given data set. Round
your answer to two decimal places. Also interpret how the mean absolute deviation will
change, if the value of 65 is removed.

Mean Absolute Deviation with ‘65’ = Prizes won by the students

Mean Absolute Deviation without ‘65’ = 15 22 12 73 44 56 65

interschool competition. Find the mean absolute deviation of the given data set. Round
your answer to two decimal places. Also interpret how the mean absolute deviation will
change, if the value of 65 is removed.

Mean Absolute Deviation with ‘65’ = 21.14 Prizes won by the students

Mean Absolute Deviation without ‘65’ = 20.67 15 22 12 73 44 56 65

Mean Absolute Deviation with ‘65’ > Mean Absolute Deviation without ‘65’

The data values without ‘65’ are closer to the mean than the data values with ‘65’.
