Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are. video https://cdn.kastatic.org/googleusercontent/Oratxu6gscuquGwoMyuDlOPqg5bQmTT_4_9zkhnlmjE1umgQ5oyLBqRqcSXAhlW-OhBt1YhuOWXscL4z8EDFX0Bg Mean absolute deviation (MAD) Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.

The graph shows the number of bubbles blown by four people. The mean is found by adding all the values and dividing by the number of data points. The MAD is calculated by finding the average of the absolute differences from the mean. video https://cdn.kastatic.org/googleusercontent/PGSQrj24qymmwdkCkzWuG4U-XlOxBF96Bcceq_wlPxgoxV0XyKIfU8xZ3u0OJ5JjXHmd9RQsbti-eMNU8RPfn-4H Mean absolute deviation example This lesson teaches how to calculate the mean and mean absolute deviation (MAD) using a bar graph.

We begin by working through an example, showing how to calculate the mean. Then, we find the absolute deviations from this mean, multiply them by their respective frequencies, sum these products, and finally compute the mean deviation about the mean. We'll also outline the step-by-step method for this calculation.

We'll walk through an example, starting with finding cumulative frequencies and determining the median value. Then, we'll calculate the absolute deviations of each observation from the median, find their products with the corresponding frequencies, sum these products, and finally, divide by the total number of observations to get the mean deviation about the median. The general steps for this calculation will also be outlined.

We'll tackle an example, starting with finding mid-points and cumulative frequencies. A key part is calculating the median for continuous data using its specific formula (l plus (N by 2 minus C) divided by f, all times h). Once the median is found, we'll proceed to find the absolute deviations, their weighted sum, and finally the mean deviation. The general steps for this process will also be outlined.
