Julia has the greater median

Julia also has the greater mean.

Averagely, Julia practiced for a greater amount of time each day.

What is the Mean and Median of a Data Set?

Mean = sum of data points / number of data points.

Median = center/middle of the data distribution.

Mean for Julia = (20 + 20 + 30 + 60 + 60 + 60 + 70 + 70 + 100 + 100 + 100 + 115 + 115 + 115)/14 = 69.6

Mean for Hannah = (20 + 20 + 30 + 30 + 45 + 45 + 45 + 70 + 70 + 70 + 75 + 90 + 90 + 120)/14 = 58.6

Median for Julia = 70

Median for Hannah = (45 + 70)/2 = 57.5

Julia has the greater median and also has the greater mean.

Averagely, we can conclude that Julia practiced for a greater amount of time each day.
