Find the mean, and put these numbers all in order from least to greatest

Question

173 279 636 357 384 320 288 420 401 389

Answer 1

To find the mean of these numbers, you need to add them all together and then divide by the total number of numbers.

Adding the numbers: 173 + 279 + 636 + 357 + 384 + 320 + 288 + 420 + 401 + 389 = 3,447

Total number of numbers: 10

Mean: 3447 / 10 = 344.7

Now let's put the numbers in order from least to greatest:

173, 279, 288, 320, 357, 384, 389, 401, 420, 636

Answer 2

Find the mean absolute deviation (MAD) of your data. Show all the steps.

Answer 3

To find the mean absolute deviation (MAD), you need to follow these steps:

1. Find the mean of the data. In this case, the mean is 344.7.

2. Subtract the mean from each number in the data set.

173 - 344.7 = -171.7
279 - 344.7 = -65.7
288 - 344.7 = -56.7
320 - 344.7 = -24.7
357 - 344.7 = 12.3
384 - 344.7 = 39.3
389 - 344.7 = 44.3
401 - 344.7 = 56.3
420 - 344.7 = 75.3
636 - 344.7 = 291.3

3. Take the absolute value of each of these differences.

|-171.7| = 171.7
|-65.7| = 65.7
|-56.7| = 56.7
|-24.7| = 24.7
|12.3| = 12.3
|39.3| = 39.3
|44.3| = 44.3
|56.3| = 56.3
|75.3| = 75.3
|291.3| = 291.3

4. Find the mean of these absolute differences.

(171.7 + 65.7 + 56.7 + 24.7 + 12.3 + 39.3 + 44.3 + 56.3 + 75.3 + 291.3) / 10 = 782.1 / 10 = 78.21

Therefore, the mean absolute deviation (MAD) of the data is 78.21.
