a. symmetrical
b. skewed to the left
c. having a floor effect
d. skewed to the right

Answer 1

The distribution of test scores would be described as skewed to the right.

Step-by-step explanation:

The distribution of test scores would be described as skewed to the right.

In a skewed right distribution, most of the scores are concentrated on the left side of the distribution, with a few lower scores on the right side. This means that most students did well on the first exam, while only a few students did poorly.

For example, if the mean score is higher than the median score, and the mode is lower than the median, then the distribution is skewed to the right.
