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.

I'm finding the difference between every data point and the mean, squaring them, summing them up, and then dividing by that number of data points. So I'm taking the average of these …

Now I know that the IQR is defined differently from field to field, but as far as I know the quantile function x_p is defined the same for all fields of science or at least in statistical mathematics, …

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set.

In terms of scatterplots, being one-sided does not necessarily mean that the data points are not scattered. The scatter in the data points will still be visible in the one-sided residual plot.

6x + 5x = 11x 2 and 8 doesn't have x. So we can combine them. 2 + 8 = 10 Thus 6x + 5x + 2 + 8 = 11x + 10 Check this out for a clearer explanation: https://www.khanacademy.org/math/cc …
