Find the mean, median., mode, and range of each data set after you perform the given operation on each data value.
23, 21, 17, 15, 11; subtract 3
Find mean , median , mode , and range of the given data after performing the given operation first to each data value.
Answer to Problem 20P
Mean = 13.5
Median = 13
Mode = no mode
Range = 12
Explanation of Solution
Given:
23 , 21 , 17 , 15 , 12 , 11 ; subtract 3
Calculation:
Perform the given operation to each data value:
20 , 18 , 14 , 12 , 9 , 8
Arrange the given data in ascending order :
8 , 9 , 12 , 14 , 18 , 20
Mean =
Median = The
Mode = The entry that appeares maximum number of times = since all the data values occur only once , so , there is no mode.
Range is the difference of the highest and lowest value of the data = 20-8 =12
