Question

How to find the mad of the set of data?

Answer 1

Answer:

Here is an example..:

Find the M.A.D of the set of data

10.2 , 9.4, 11.3, 12.9

( so, we just have to add up all numbers )

10.2 + 9.4 + 11.3 + 12.9 = 43.8

Then we divide them by 4, you might be wondering..why 4?

that's because there are about 4 numbers in the data set.

So:

43.8

____= 10.95 (we found the mean! :D)

  4

After that, we just have to subtract the mean (10.95) to the same numbers (or the so called data set)

10.95 - 10.2 = 0.75

10.95 - 9.4 = 1.55

10.95 - 11.3 = 0.35

10.95 - 12.9 = 1.95

For our final step, we just add up all the difference, then,  divide it by 4 again.

0.75 + 1.55 + 0.35 + 1.95 = 4.6

                                          --------- = 1.15

                                              4

Answer 2

Answer:

add up all numbers

then divide that number by the amount of numbers.

Step-by-step explanation:

mad is basically finding the average of a set of numbers.

and how do you do that?

first, add up all numbers

ex: 1, 5,3,10,6,20,15,15,14  --> this adds up to 90.

then divide that number by the amount of numbers.

count how much numbers ehere are: there are 9 numbers.

divide 90 by 9 and the mad/average is 10.
