The correct is 1. There is more variation in the science scores.
Tyrell recorded his science scores and his math scores. The measures of center and variation for each score are shown in the table below.
Measures of Center and Variation for Tyrell’s Science Math
Mean 78 80
Median 80 80
Mode 60 85
Range 40 15
Mean Absolute Deviation 14.4 4.0
The larger mean absolute deviation represent the greater variation.
Since the mean absolute deviation of science score is more than the math score, therefore There is more variation in the science scores.
Hence the correct option is 1.
Mean is the best measure of the typical score of both science and math because it includes all the values.
Therefore option 3 is incorrect.
Mean of science is 78 and median of science is 80.
Since 78≠80, therefore mean and median are not same.
Therefore option 4 is incorrect.
