Question

14. Find the mode, and the mean for the set of data below.
Number of fiction books read by 28 eight-grade pupils :
4,6, 1, 7, 3, 9, 5, 7, 8, 5, 4, 6, 10, 6, 9, 5, 6, 6, 8, 6, 8, 5, 10, 7, 2,5,3,7.​

Answer 1

Step-by-step explanation:

solution------>

Given:-

4,6,1,7,3,9,5,7,8,5,4,6,10,6,9,5,6,6,8,6,8,5,10,7,2,5,3,7

as we all know

mode:-

mode is the value which occure most frequently in a set of observation .it is the point of maximum frquency

there for,

in the given data 6 occures most time

mode =6

now for mean

$mean = \frac{sum \: of \: all \: observation}{total \: number \: of \: observation} \\ \\ mean = \frac{168}{28} \\ \\ mean = 6$

Answer 2

For given set of data mean and mode are:----

●Mode of a set of data values is the value that appears most often.

For given set we have:--

Number of time 5 appears is 5

Number of time 6 appears is 6

Number of times 7 and 8 appears is 3 and3 .

So maximum times a number appears is mode ,so mode of given set of data is 6.

●Mean is the average of the numbers.

There are 28 numbers in given set so mean= sum of all numbers/total number

Total number are 28

Mean=sum /28

Sum of all is 168

Mean=168/28=6

So mean=6

Hence mode and mean both are equal to 6.
