1. Give an example of using a weighted mean. how might it be a better average than another measure of center like the mean?

2. Fill in the second column of the table
with any numbers you want.
This column will represent number of students
who had a certain score on a test.

Score N (weight)
60
70
80
90


Calculate Weighted Mean for the score on this test.

Discussion C:  The mean and the median are two types of measures of center.

1. Give a real-world example of when the median is preferred over the mean. Refer to the eText and resources in the course Materials folder.

2. Create your number collection, any 7-12 numbers of your choice.

Arrange them in order and find Median and Mean.

This week we study Normal Distribution. Part 1. Demonstrate that you understand basic concept of Normal Distribution. In two small paragraphs describe a couple of properties/rules of Normal distribution. Give one example of some practical case where we can use Normal distribution (for instance, IQ scores follow a normal distribution of probabilities with the mean IQ of 100 and a standard deviation around the mean of about 15 IQ points.) Part 2. Assign your numbers for mean μ and standard...

T-tests are used when you want to examine differences but you do not know everything about the population. There are three types of t-tests that you may choose to do: one-sample t-test, independent sample t-test, or dependent sample t-test. You can calculate these by hand, in SPSS, or in Excel. The instructions below can be used for SPSS and your textbook offers instructions for using Excel. Single-sample t-tests These tests are used when you want to determine the probability that...
