How to find the mean absolute deviation of 2,4,0,3,4,1,3,1,1,5?

Here's how to calculate the M.A.D

First: Find the mean.

(heres how)

How to find the mean:  Add the data points.  then divide them by the number of data points, which in this case is (9)  

Second: Fiugre out or calculate how far away each data point is from the mean using positive distances. These are called absolute deviations, or A.D.

Take the data points and subtract them by the mean.

For example,

∣10−16∣=6

∣18−16∣=2

Third: Add the deviations together.  

Example: (6+2)

Last but not least: Divide the sum by the number of data points.  (9)

And there's your answer!  Comment down below for a more specific answer if needed.

Brainliest would be much appreciated.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
