The table below shows the number of candles Stevie sold at her shop for the past year:

January 20 July 30
February 45 August 137
March 35 September 49
April 63 October 60
May 42 November 109
June 98 December 85


a. Determine the mean number of candles sold each month
b. Determine the median number of candles sold.

 

Answer:

a. Mean = 65

b. Median = 54.5

Step-by-step explanation:

January - 20

February - 45

March - 35

April - 63

May - 42

June - 98

July - 30

August - 137

September - 49

October - 60

November - 109

December - 85

To get the mean, also known as the average, add all the numbers in the given data set then divide it by 12 since there are 12 months.

20 + 45 + 35 + 63 + 42 + 98 + 30 + 137 + 49 + 60 + 109 + 85 = 773

773/12 = 64.4166666667

Rounded off to the nearest whole = 65

To get the median, arrange the numbers in ascending order (least o greatest) then get the two middle scores since 12 is an even number. Afterwards, add the two middle scores then divide the sum by 2.

20, 30, 35, 42, 45, 49, 60, 63, 85, 98, 109, 137

Middle numbers = 49 and 60

49 + 60 = 109

109/2 = 54.5

The median is 54.5
