Question

Find mean, mode & range for given data (a) 5,7,2,3,7,9,7,8,6,5,7​

Answer 1

Step-by-step explanation:

Mean:-

Explanation:-

Mean is a number that represents the central tendency of a group.

As we know,

First we have to add the sum of given numbers. Secondly we have to divide the sum with the total number of given numbers.

Step 1:-

Add all the given numbers:-

5+7+2+3+7+9+7+8+6+5+7

=66

Step 2:-

Divide the sum of number with the total number of given numbers:-

Sum of number= 66

Total number= 11

So, we have to do division of 66 an 11:-

66÷11=6

Mean= 6

Mode:-

Explanation:-

Mode is the score which repeats the highest number of times in any data.

Given numbers:-

5,7,2,3,7,9,7,8,6,5,7

So,

7 has repeated 4 times

5 has repeated 2 times

other numbers have repeated once.

Hence,

Most repeated number= 7

Mode of data= 7

Range:-

Explanation:-

The range is the difference between the largest and smallest numbers.

Given numbers:-

5,7,2,3,7,9,7,8,6,5,7

So,

Highest number= 9

Lowest number= 2

Range=(H-L)

= 9-2

= 7

Range= 7
