Use the following data to answer all questions


15, 17, 18, 12, 17, 18, 13, 13, 19, 15, 16, 15, 15, 16

1(A) List the data set from Least to greatest. Separate values with a comma.

12, 13, 13, 15, 15, 15, 15, 16, 16, 17, 17, 18, 18, 19

Use the following data set to answer all questions

15, 17, 18, 12, 17, 18, 13, 13, 19, 21, 19, 15, 16, 15, 15, 16

Mean=____. Median=_____.

Mode=____. Range=_____.

Mean = (15+17+18+12+17+18+13+13+19+21+19+15+16+15+15+16)/16 = 225/16 = 14.06

To calculate the median, we first order the data set from least to greatest:

12, 13, 13, 15, 15, 15, 15, 16, 16, 17, 17, 18, 18, 19, 19, 21

The median is the middle value, which in this case is the average of the two middle values: (16+17)/2 = 16.5

The mode is the most common value in the data set, which is 15.

The range is the difference between the largest and smallest values in the data set: 21-12 = 9.

Therefore,

Mean = 14.06.

Median = 16.5.

Mode = 15.

Range = 9.
