Population Means and Proportions Essay
Module 4 – Drawing Inferences about Population Means and
Proportions! Upon successful completion of this module, you will
be able to satisfy the following outcomes:
· Discuss the procedure for hypothesis testing.
· Define the possibility for measurement error and describe how
possibility for measurement error can apply to data collection.
· Identify the types of variables needed in Chi square, one-sample
t-test and paired t-test.
Now that we’ve covered the logic upon which statistical
hypothesis testing is based, we can apply that logic to drawing
inference in comparing groups.
The t-test is used to assess whether the means of two groups are
statistically different from one other. When examining the
differences between scores of two groups, we judge the
difference between their means relative to the spread or
