Find the mean, median., mode, and range of each data set after you perform the given operation on each data value.
3.2, 4.4, 6, 7.8, 3, 2; subtract -4
Find mean , median , mode , and range of the given data after performing the given operation first to each data value.
Answer to Problem 24P
Mean = 8.4
Median = 7.8
Mode = no mode
Range = 5.8
Explanation of Solution
Given:
3.2 , 4.4 , 6 , 7.8 , 3 , 2 ; subtract -4
Calculation:
Perform the given operation to each data value:
7.2 , 8.4 , 10 , 11.8 , 7 , 6
Arrange the given data in ascending order :
6 , 7 , 7.2 , 8.4 , 10 , 11.8
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 =11.8 − 6 = 5.8
