CeeCee recorded the number of necklaces for sale at 10 different locations and then arranged the numbers from smallest to largest. The numbers of necklaces for sale at the locations were 4, 4, 4, 5, 8, 9, 9, 9, 9, and 9.The mean number of necklaces for sale at the locations was 7.What is the mean absolute deviation?

Answer 1
Answer:
Ok screw it, I went and watched a video on it
You calculate MAD by working out the absolute value that each data point is away from the mean
To do so, subtract each point from the mean, and then you don't care if the result is positive or negative, you just write it as positive
So
4 - 7 = -3, deviation is 3
4 - 7 = -3, deviation is 3
4 - 7 = -3, deviation is 3
5 - 7 = -2, deviation is 2
8 - 7 = 1, deviation is 1
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
9 - 7 = 2, deviation is 2
Now, you add up all the deviations, and divide them by the number of points of data you have, so
(3 + 3 + 3 + 2 + 1 + 2 + 2 + 2 + 2 + 2)/10, or simply
22/10
So the MAD is 2.2
I think

To reduce down a fraction you can try to find factors that go in both the numerator (top # of fraction) and denominator (bottom #)
So, for 6/9, 3 goes in both of them. When you divide each number by 3 you get:
2/3

Hi there!
I can't post a drawing for this, but I will try to explain using my own words on what 6/9 is in it's simplest form.
The number three can go into 6 and 9. Three goes into 6 twice, and it goes into 9 three times.
So our simplified answer is 2/3.
In decimal form this is 0.66666667 (repeating decimal but rounded off to 0.6667)
Hope this helps!
