**Week 8 HOME PAGE**

*Week 8 will serve as your introduction to one of the end products of this course of inferential statistics... hypothesis testing. This is where all of the rules we learned for collecting and defining sample data are used to actually make decisions based on the inferential statistical values we have derived from the sample data. This basic course is just the beginning of the world of decision making based on inferential statistics that awaits you in your chosen field of study. Inferential statistics is used in every discipline, and nearly every facet of our lives is influenced by some decision made using inferential statistics.*

*The final concepts you need to understand for this course will serve as an introduction to correlation and regression analysis. You will learn how to know if two behaviors are related to one another, and how strong that relationship is... mathematically speaking. We will use the concepts learned in Week 2 on paired data and scatter plots to determine a linear trend indicating correlation. With the existence of a strong correlation we can use the scatter plot values to determine the equation of the "best fit" line, called the regression line. The regression equation can be used for predicting the value of a dependent variable based on the value of an independent variable.*

*We skipped sections in the textbook dealing with inferences on proportions and variances, but they are done basically the same way we make inferences about means. We also only made inferences on one population mean. More advanced courses will look at these concepts and expand it to comparing two or more population means. Having learned the basic concepts of statistics, you should pick those procedures up very quickly.*

**WEEK 8: Hypothesis Testing/Correlation and Regression**

**Weekly Objectvies:
**The student will be able to...

1. Define the basics of hypothesis testing by using one-sample procedures for the hypothesis test of the population mean.

2. Define the purpose of regression and correlation analysis.

3. Apply linear regression analysis and simple linear correlation analysis.

• **Perform hypothesis tests involving one population.**

• **Compute regression and correlation of Bi-variate data.**
