How do you find the equation of the line of best fit?

Back

You can find the equation of the line of best fit using methods such as least squares regression.

What is the Mean Absolute Deviation (MAD)?

Back

MAD is a measure of the dispersion of a set of data points, calculated as the average of the absolute differences between each data point and the mean.

Front

What is the first step in calculating the Mean Absolute Deviation?

Back

The first step is to find the mean of the data set.

Front

How do you calculate the Mean Absolute Deviation?

Back

1. Find the mean of the data. 2. Calculate the absolute differences from the mean. 3. Find the average of those absolute differences.
