Based on this information, what conclusion can be drawn from these two sets?

a. The median was greater than the mean in the second set.

b. The mean was greater than the median in the second set.

c. The standard deviation in both sets revealed a positive correlation between the data.

d. Most data points were closer to the mean in the first set than in the second.

e. Most data points were closer to the mean in the second set than in the first.
