Answer:
Step-by-step explanation:
Mode = 12
Range = Maximum value - Minimum value
= 38 - 12
= 26
Median:
Arrange in ascending order:
12 , 12 , 15 , 24 , 31 , 38
If number of data set is even, find the average of n/2 and (n/2) + 1th term
Number of data set = 6
Median = average of 3rd and 4th term
[tex]= \dfrac{15+24}{2}=\dfrac{39}{2}=19.5[/tex]
Median = 19.5
[tex]Mean = \dfrac{Sum \ of \ all \ data}{number \ of \ data \ set}\\\\=\dfrac{24+31+12+38+12+15}{6}\\\\\\=\dfrac{132}{6}\\\\= 22[/tex]
