Question

3. Mean

a) Many people already know how to find the mean (average) of a sample of data by "adding all the numbers and dividing by the number of values in the dataset." Read Chapter 4, and then describe, in your own words, another method of finding the mean by using the sample space (list of possible values) and probabilities (the technique is in the book). Create a list of seven, 2-digit numbers (with no duplicates) and another set of seven probabilities (with no duplicates). The probabilities must add to 1.

Open R, and manually enter those numbers and their corresponding probabilities to calculate the mean using only addition and multiplication (in other words, enter only the numbers, the plus sign, and the * for multiplication, like on the bottom of Yakir, 2011, p. 57). Paste all the R output into your learning journal.

b) Describe in your own words what your calculation is doing and what the answer means.

Data
For Tasks 1-8, consider the following data:
7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5, 13.0, 3.2, -1.1,
7.0, 0.5, 3.9, 2.1, 4.1, 6.5
In Tasks 1-8 you are asked to conduct some computations
regarding this data. The computation should be carried out
manually. All the steps that go into the computation should be
presented and explained. (You may use R in order to verify your
computation, but not as a substitute for conducting the manual
computations.)

1. Flip a coin 120 times. In order to be organized, please
record the results of this experiment in 5 rows, with 24 flips per
row. For example, the first row may be
HTHTTTHTTHTTHHHTTHTHHHHT
If you do not desire to flip a coin manually, STATDISK can be
used to simulate the process. To use STATDISK, go to “Data” at the
top of the STATDISK window, and then choose “Coins Generator”. The
“Coin Toss Simulator” window will appear. Then...
