I really need help. 50 points. 2 data sets.
I need mean, median, range, IQR, standard deviation.

Set A.
77 64 66 100 55 79 80 84 83 71 79
Set B
99 28 54 71 87 92 87 85 77 72 79

A. 76.2 (mean), 79 (median), 45 (range), 66 and 83 (IQR), 11.42 (standard deviation)

B. 75.5 (mean), 79 (median), 71 (range), 71 and 87 (IQR), 18.94 (standard deviation)

Step-by-step explanation:

- First, rearrange the numbers from descending to increasing order.

- Mean is all numbers added up divided by how many numbers their are.

- Median is center number.

- Range is largest number divided by lowest.

- IQR is when you separate your set of numbers in half and find the center of each half. That is why their is two sets of numbers.

- Standard deviation is a measure of the amount of variation or dispersion of a set of values.

-  Hope this helps! If you need more help or a further explanation please let me know; I would be glad to help.
