Answer 2

Answer :

• Mean is 24
• Median is 25

Given :

• 22,24,26,22,24,26,24,22,22,28

To find :

• Mean and Median

Solution :

(1) Mean :

• 22,24,26,22,24,26,24,22,22,28

As we know that

• Mean = Sum of observations/Number of observations

Where,

• Sum of observations is 22,24,26,22,24,26,24,22,22,28
• Number of observations is = 10

⇢ Mean = 22 + 24 + 26 + 22 + 24 + 26 + 24 + 22 + 22 + 28 / 10

⇢ Mean = 240/10

⇢ Mean = 24

Hence , Mean is 24.

(2) Median :

• 22 , 24 , 26 , 22 , 24 , 26 , 24 , 22 , 22 , 28

As we know that,

• Median = (n/2)th term + (n/2 + 1)th term /2

⇢ 24 + 26 / 2

⇢ 50/2

⇢ 25

Hence,Median is 25.
