Find the median of first 5 positive multiples of 5.
Answers
Answer:
Mean is the sum of the data values divided by the total number of values in the data set.
Median is the middle value of the data values after arranging the data values in the ascending or descending order.
If n is odd, then the median is (
2
n+1
)
th
value.
If n is even, then the median is
2
(
2
n
)
th
+(
2
n
+1)
th
value.The first 10 positive multiples of 5 are 5,10,15,20,25,30,35,40,45,50
Given that mean is m
Therefore, m=
10
5+10+15+20+25+30+35+40+45+50
m=
10
275
=27.5
Given that median is M
Total number of values is n=10 (even) then
the median is M=
2
(

)
th

=27.5
Therefore, m−M=27.5−27.5=0
Step-by-step explanation:
I hope this will help you
Step-by-step explanation:
= 27.5
Therefore, m- M = 27.5 - 27.5 = 0
