Question

hlo guys.........Find the value of λ , if the mode of the following data is 20 :

15, 20, 25, 18, 13, 15, 25, 15, 18, 17, 20, 25, 20, λ , 18.​

Answer 1

Given,

Observations = 15, 20, 25, 18, 13, 15, 25, 15, 18, 17, 20, 25, 20 and 18

Since we know,

The observation with highest frequency is the mode.  

Given mode is 20  

According to question,

Observations 15, 18, 20 and 25 are repeated 3 times

Since the mode is 20,

Therefore, the value of lambda will be 20

Hence,

Lambda = 20

Answer 2

Answer:

• Given observations are: 15, 20, 25, 18, 14, 15, 25, 15, 18, 16, 20, 25, 20, x, 18.
• Recall that the observation with highest frequency is the mode.
• Given mode is 25 Notice that observations 15, 18, 20 and 25 are repeated 3 times.
• Since the mode is 25, hence the value of x should be 25 ∴ x = 25
