Question

For the following set of baseball runs scored at each game, identify:

• The mean
• The median
• The mode
• The range
• The interquartile range

12, 16, 16, 21, 22, 25, 28
Which measure of center would the baseball team want to use to show what a great team they are--the mean or the median?

Answer 1

They would want to use the larger number, which in this case is the median--21

The mean is a smaller number (20)

Answer 2

mean (average) : (12+16+16+21+22+25+28) / 7 = 140/7 = 20
median (middle number) = 21
mode (number that appears most often) = 16
range (largest number - smallest number) = 28 - 12 = 16

Q1 = 16
Q2 = 21
Q3 = 25
IQR = Q3 - Q1 = 25 - 16 = 9

not sure about the last part....I am thinking median
