Standard Error of the Mean
Average amount of deviation of a sample mean.


Varies directly with SDpop
Varies indirectly with N
Region of Unlikely Values
Rejection Region
At tail end of curve
Unlikely that a researcher will obtain means in this region simply because of chance.
Corresponds to alpha level (when .05, rejection region is 5% of curve).
**When obtained values fall in rejection region, null is rejected, and tx had an effect.
Type I Error
Null is incorrectly rejected, i.e., differences were found and they do not exist.

**Size of alpha directly corresponds to the likelihood of making this error.
Type II Error
The null is incorrectly accepted, i.e., no differences are found when differences actually do exist.

**Probability of making this error corresponds to beta (inverse relationship w/ alpha).
When null is rejected and it turns out to be correct.
Ability to correctly reject the null.
Increased when sample size is large, random error is small, magnitude of intervention is large, statistical test is parametric, and test is one-tailed.
**Power=1-beta. Beta has the most significant and measurable effect on power. As alpha increases, so does power.
