To find the median of a distribution, we need to arrange the values in order from lowest to highest or highest to lowest. Then, we locate the middle value of the distribution.
If the number of values is odd, the median is the middle value. In this case, we have five values, which is an odd number. Therefore, we can directly locate the middle value.
If the number of values is even, the median is the average of the two middle values. In this case, we do not have an even number of values.
Arranging the given values in order from lowest to highest, we have:
4, 4.5, 5, 6.5, 9
The middle value of this distribution is 5, which is the third value in the ordered set. Therefore, the median of this distribution is 5.
