Alicia begins to find the mean absolute deviation of this data set. she finds the mean of the data and then finds the distance between each data point and the mean. what should she do next?

See below.

Step-by-step explanation:

Add the distances up.

Then the MAD is the sum divided by the  number of data points.

Find the average of the distances from the mean.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
