What is the mean absolute deviation , 5, 1, 6, 2, and 3

MAD = 1.68

Step-by-step explanation:

So easily we calculate our mean => 5 + 1 + 6 + 2 + 3 = 17

17/5 = 3.4

3.4 is our mean or average

Now we find how much each of those is away from 3.4

--> 5 - 3.4 = 1.6

3.4 - 1 = 2.4

6 - 3.4 = 2.6

3.4 - 2 = 1.4

3.4 - 3 = 0.4

1.6 + 2.4 + 2.6 + 1.4 + 0.4 / 5 =

8.4 / 5 = 1.68

Thus, our mean absolute deviation (MAD) = 1.68

Hope this helps!

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
