The table shows the test scores of students who studied for
a test as a group (group a) and students who studied
individually (group b).
student test scores (out of 100)
which would be the best measures of center and variation to
use to compare the data?
group a 848077 96 92 84 92
group b 92 86 85 8783 8583768088
the scores of group b are skewed right, so the mean
and range are the best measures for comparison
both distributions are nearly symmetric, so the mean and
the standard deviation are the best measures for
comparison.
both distributions are nearly symmetric, so the median
and the interquartile range are the best measures for
comparison
the scores of both groups are skewed, so the median
and standard deviation are the best measures for
comparison
