Answer:

3.B

4.C

5.A

Step-by-step explanation:

The mean and the median are both measures of central tendency; they give an indication of the average value of a distribution of figures.

The median is the middle score in a list of scores; it is the point at which half the scores are above and half the scores are below. Medians are less sensitive to extreme scores and are probably a better indicator generally of where the middle of the class is achieving, especially for smaller sample sizes.
