- Arithmetic Mean: The most common sample value of data is mean. We define it as the sum of values divided by number of terms.
- Range: The difference between the highest and the lowest term is range.
- Mode: The mode is the observation that occurs most in the data.
- 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.

### Important Questions on Class 7 Maths Chapter 3

### 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

Mode is the observation occurred the highest number of times = 14

Median is the middle observation = 14

### Tell whether the statement is true or false: The mode is always one of the numbers in a data.

True.
