Means-to-MAD relationship is something that it would not be difficult to find, but I've certainly never heard of it.The mean (µ) of a set of data points is found by adding them up and dividing by the number of data points.For our first game: For the second group: the average absolute deviation is when you find the distance of each data point from the mean and then find the average of these distances.For our first game: For the second group: it would not be difficult to find the relationship between these for each set as a question...don't forget to put our relationship in its simplest form!For the first set: For the second group: (In a fraction, you just put this as a 3 because the ÷1 is redundant...however, because this is the relationship, we have to keep it in)
