FAQs on Examples: Mean & Range of Data- 2 Video Lecture - Advance Learner Course: Mathematics (Maths) Class 6

1. What is the concept of mean in data analysis?

Ans. The mean is a measure of central tendency in data analysis. It is calculated by summing up all the values in a data set and then dividing the sum by the total number of values. The mean provides an average value that represents the overall trend or central value of the data.

2. How can the mean be calculated for a given data set?

Ans. To calculate the mean of a data set, you need to add up all the values in the set and then divide the sum by the total number of values. For example, if you have 5 numbers: 2, 4, 6, 8, and 10, you add them up (2 + 4 + 6 + 8 + 10 = 30) and then divide by 5 (the total number of values), resulting in a mean of 6.

3. What does the range represent in data analysis?

Ans. The range is a measure of variability in data analysis. It represents the difference between the largest and smallest values in a data set. The range provides information about the spread or dispersion of the data points, indicating the extent of variation within the set.

4. How can the range be determined for a given data set?

Ans. To determine the range of a data set, you need to identify the largest and smallest values in the set and then subtract the smallest value from the largest value. For example, if you have the numbers 4, 8, 12, 16, and 20, the largest value is 20 and the smallest value is 4. Therefore, the range would be 20 - 4 = 16.

5. How are the mean and range useful in data analysis?

Ans. The mean and range are useful measures in data analysis as they provide valuable insights into the data set. The mean helps to understand the central tendency or average value of the data, while the range indicates the variability or spread of the data points. These measures enable comparisons, identifying outliers, and analyzing trends within the data set.
