A researcher divides some marbles into two data sets. In Data Set​ 1, the mean mass of the marbles is 18.7 g. In Data Set​ 2, the mean mass of the marbles is 11.1 g. The mean absolute deviation of both data sets is 4. What can you infer about the two sets of​ marbles?
Question content area bottom
Part 1
There is
▼
difference in the​ distributions, because the difference in mean mass between Data Set 1 and Data Set 2 is
▼
very small
large
compared to the mean absolute deviation. The MAD means that
▼
each set of marbles has a differently dash shaped distribution.
both sets of marbles have similar distributions.
