Question

an observation of the number of day in every month of a leap year was made . what is mode of such observation?

Answer 1

Answer:

mode = 31

Step-by-step explanation:

here the observations are number of days in each month

that is we will write represent data in raw data form representing the number of days in every month of a leap year.

therefore the 12 observations will be

31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31

mode is the highest repeated value in the dataset (represented by Z)

therefore mode in this case will be 31 (since 31 gets repeated 7 times which is the highest among all observations)

∴ mode(Z) = 31
