## FAQs on Example: Mean Deviation Method Video Lecture - Mathematics (Maths) Class 10

 1. What is the mean deviation method in statistics?
Ans. The mean deviation method is a statistical measure used to find the average deviation of a set of data from the mean. It calculates the absolute difference between each data point and the mean, sums up these differences, and then divides the sum by the total number of data points.
 2. How is the mean deviation calculated using the mean deviation method?
Ans. To calculate the mean deviation using the mean deviation method, follow these steps: 1. Find the mean of the given data set. 2. Subtract the mean from each data point to get the deviations. 3. Take the absolute value of each deviation. 4. Find the mean of these absolute deviations to get the mean deviation.
 3. What is the significance of mean deviation in statistics?
Ans. Mean deviation is a measure of dispersion that helps to understand the spread or variability of data points around the mean. It provides information about how the data points are distributed and how much they deviate from the average value. Mean deviation is useful in comparing the variability of different data sets or in assessing the consistency of a data set.
 4. How does the mean deviation method differ from other measures of dispersion like range and standard deviation?
Ans. The mean deviation method differs from other measures of dispersion like range and standard deviation in the way it considers all the data points. While range only considers the difference between the maximum and minimum values, and standard deviation takes into account the squared deviations, the mean deviation method considers the absolute deviations from the mean for each data point. This makes it more robust to extreme values and gives a better understanding of the overall variability.
 5. Can mean deviation be negative?
Ans. No, mean deviation cannot be negative. Mean deviation measures the average deviation of data points from the mean, and the absolute value of each deviation is taken to eliminate negative values. Therefore, the mean deviation is always a positive value or zero if all the data points are equal to the mean.
