Explanation of Question 2

Question 2 under the Data Handling lesson in Class 8 Maths textbook requires the students to identify the mode of the given data. The mode is a measure of central tendency that represents the value that occurs most frequently in a dataset. To solve this question, the students need to follow the given steps:

Step 1: Arrange the data in ascending or descending order.

Step 2: Count the frequency of each value in the dataset.

Step 3: Identify the value that occurs most frequently. This value is the mode.

In case there are multiple modes in the dataset, the students need to report all of them. If there is no value that occurs more than once in the dataset, then there is no mode.

Example:

Let's consider an example to understand the process of finding the mode. The given dataset is:

23, 25, 27, 28, 23, 29, 23, 25, 26, 28, 26, 23, 27

Step 1: Arrange the data in ascending or descending order.

23, 23, 23, 23, 25, 25, 26, 26, 27, 27, 28, 28, 29

Step 2: Count the frequency of each value in the dataset.

23 - 4, 25 - 2, 26 - 2, 27 - 2, 28 - 2, 29 - 1

Step 3: Identify the value that occurs most frequently. This value is the mode.

The value 23 occurs most frequently, so the mode of the dataset is 23.

Conclusion:

In conclusion, finding the mode of a dataset involves arranging the data in order, counting the frequency of each value, and identifying the value that occurs most frequently. This measure of central tendency is useful in identifying the most common value in a dataset.
