Question

hence
The following is the number of books issued
a college library on 10 different days. Lets
92, I46, 88,200, 99,100, 75,200,95,105
Calculate arithmetic mean, median and mode
​

Answer 1

Mean=120

Mode=200

Median=99

Explanation:

Mean=Total of observations/Number of observations

First arrange in ascending order,

75,88,92,95,99,100,105,146,200,200

=1200/10

=120

Mean=120

Mode=200

As it occours 2 times

Median=10/2

=5

5th observation is 99

Median=99

Answer 2

mode of the data is 200

mean =sum of all observation/total observation

mean= 92+146+88+200+99+100+75+200+95+105/10

mean = 1200/10

mean=120

median = n/2+(n/2+1)/2

ascending order 75,88,92,95,99,100,105,146,200,200

median=10/2+(10/2+1)/2

median=5+6/2

median=11/2=5.5

median is 100 or 99
