### The scores in mathematics test (out of 25) of students is as follows: 19, 25, 23, 20, 9, 20, 15, 10, 5, 16, 25, 20, 24, 12, 20. Find the mode and median of this data. Are they same?

Arranging the given data in ascending order:

= 5, 9, 10, 12, 15, 16, 19, 20, 20, 20, 20, 23, 24, 25, 25

Mode is the observation occurred the highest number of times.

Therefore, Mode = 20 Median is the middle observation = 20

Yes, Mode and Median are same of given observation.

### Find the mode and median of the data: 13, 16, 12, 14, 19, 12, 14, 13, 14.

Arranging the given data in ascending order, 12, 12, 13, 13, 14, 14, 14, 16, 19

##### About NCERT Solutions for Class 7 Maths Chapter 3

In 7 Maths Chapter 3 we know about Data Handling. We will study about statistics section of mathematics. It has the collection of data and then their proper likeness to learn. The following are the tools or methods to show:

1. *Arithmetic Mean*: The most common sample value of data is **mean**. We define it as the sum of values divided by number of terms.

2. *Range*: The difference between the highest and the lowest term is **range**.

3. *Mode*: The **mode** is the observation that occurs most in the data.

4. *Median*: First, arrange the data in ascending or descending order. The **median** gives us the middle observation.

The above mentioned term provide us a numerical value related to our data. but the Bar Graph provides us a visual representation about the collected data. The concept of probability is also introduced in this chapter. There are situations in our life, that are certain to happen, have probability 1. Some that are impossible and some that may or may not happen, have probability 0.
