summary - what does mad mean? what is mad and what does it represent? mad is it represents image with mean (dashed horizontal line) and a red vertical bar buttons: image, microphone, square root, ±, share with class

Explanation:

MAD stands for Mean Absolute Deviation. It is a statistical measure that calculates the average distance between each data point and the mean of the dataset. Mathematically, for a dataset \( x_1, x_2, \dots, x_n \) with mean \( \bar{x} \), the MAD is calculated as \( \text{MAD}=\frac{1}{n}\sum_{i = 1}^{n}|x_i-\bar{x}| \). It represents the average amount of variation or dispersion from the mean, giving an idea of how spread out the data is around the mean.

Answer:

MAD stands for Mean Absolute Deviation. It is calculated as the average of the absolute differences between each data point and the mean of the dataset (\(\text{MAD}=\frac{1}{n}\sum_{i = 1}^{n}|x_i-\bar{x}|\)) and represents the average dispersion of data points from the mean.
