suppose 200 students take an exam, graded on a scale of 0-100%. The median exam grade was 78%, the mean exam grade was 68%, and
the range of scores was 40%. would you expect this distribution to be symmetric or skewed? Does the distribution have a high or low variation?
1 answer:
Because the median of the distribution is greater than the mean of the distribution.
Therefore, the distribution is skewed to the left.
Because the range is row (40%), the distribution has a low variation.
