For each dot plot or histogram:

Predict if the mean is greater than, less than, or approximately equal to the median. Explain
your reasoning.
b.

the following distributions?

72

78
heinht in inches

a) Mean is equal to the median, 72 inches

b) The Mean better represents this distribution.

Step-by-step explanation:

a) Finding the mean of the data

(66 + 68 + 70 +72 +74 + 76 + 78 )/ 7

=504/7 =72

The median is the center value

66,68 ,70 ,72 ,74 , 76 , 78

median is 72

Mean is equal to the median

b)

Mean better represents this distribution because this data is normally distributed.If plotted, a normal distribution curve is obtained with most of the values seen to cluster around the mean value.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
