Final Answer :
A
Explanation :
Reporting only the mean does not provide information about the range or spread of the data. Therefore, it is important to also report a measure of variability such as standard deviation, range, or interquartile range. This gives a better understanding of how close or far apart the individual scores are from the mean.
