When you find something in the results, but it never was there in the first place is called...
A Type I error

What is the ability to reject the null hypothesis?
Statistical Power

How do you attain Statistical Power?
Increase your sample size

What are the three ways to increase statistical power?
 Increase the number of subjects
 Increase the effect of size (strength of IV)
 Decrease error variability

The three ways that increase Statistical Power have an effect on what?
1  beta

Magnitude of the effect is called...
Eta (η)

If the p = .08 then we?
Failed to reject the Null Hypothesis.

When you reject the Null Hypothesis, what does that mean?
It means that there is Significance.
