A group of students created a dot plot of their heights. Based on the dot plot, find the mean and median height of the students in this class to show
To find the mean height of the students, you would add up all the heights and divide by the number of students.
To find the median height of the students, you would arrange the heights in order from smallest to largest and find the middle value.
Here is an example of a dot plot with some sample heights:
Height (in inches):
48 ●
50 ●●
52 ●●●
54 ●●
56 ●●●
58 ●
Mean height: (48 + 50 + 50 + 52 + 52 + 52 + 54 + 54 + 56 + 56 + 58) / 11 = 53.09 inches
To find the median height, arrange the heights in order: 48, 50, 50, 52, 52, 52, 54, 54, 56, 56, 58
The median is the middle value: 52 inches
Therefore, the mean height of the students is 53.09 inches and the median height is 52 inches.
