Question

The number of hours spent for studying by Geetika during a week are 8 hr, 6 hr, 9 hr, 7 hr, 11 hr, 10 hr, and 8 hr. Find the mode and median.

Answer 1

Step 1: Finding the Mode :

Mode is most repeated observations, and in the given observations, $8\mathrm{hr}$ is repeated maximum no. of times that is 2 times .

So, the Mode is 8.

Step 2: Finding the Median

Arrange the observations in ascending order as follows:

6, 7, 8, 8, 9, 10, 11

Total no. of observations in the given data is 7 that is an odd number.

So, $\mathrm{Median}=\frac{7+1}{2}=4^{\mathrm{th}}\mathrm{term}$ that is 8.
