Most statistics operate around two principles: central tendency and dispersion. Central tendency tells us where the “middle” of a set of data is, while “dispersion” allows us to see how spread out the data are from the middle.
I have attached a handout in the course content section of BB that will give you a good introduction to these two concepts. After you read it, find the mean, mode, median, midrange, range, mean deviation, variance, and standard deviation for the following set of numbers, plus a 12th number (the sum of the first three digits of your Faulkner student ID; for example, if your ID is 818523, the 12th number you would use would be 8+1+8 = 17, NOT 818). Again, you will be doing the math using 12 numbers, not just the 11 shown:
49
62
24
34
51
24
35
23
22
21
19
(Put the sum of the first three digits of your Faulkner student ID here, and use it in the computations, too) Please show me the 12th number you used, too, so I don’t have to calculate it myself (by the way, I will have your student ID numbers, so I will know the correct answer).
Each answer is worth 12 points.
If necessary, go at least two places past the decimal with your answers. For example, if the answer is 3.141, you can say “3.141” or “3.14” but not “3” or “3.1.”
