Lesson 707 After completing this lesson you will be able to say I can use variables to represent quantities that have a relationship I can show the relationship between two variables using tables and equations.

Hierarchical multiple regression. Monday 8/24/2015. What are the steps (in order) of the scientific method?. Where do you think applying . independent and dependent variables . would fall in the scientific method?. Have your homework out to be stamped!. . 11/01. 1) a) What axis is the dependent variable on? . b) What axis is the independent variable on?. 2) If you were given a table, how would you know what was the independent variable. 3) What should be at the top of every graph? (how do you write this?. Step 3: Form a Hypothesis. Hypothesis. - a . testable explanation. of an observation.. A hypothesis is . NOT just an educated guess. about what you think will happen. It must be able to be tested! . When the two samples are correlated (i.e. not independent). 1. KNR 445. Statistics. Dependent t. Slide . 2. Dependent? What’s that?. Well, not independent…2 ways….
