Failing to reject the null hypothesis (which makes me blue) when it is FALSE
What is Type II error

everyone in the population has a chance of being sampled and that probability is known
What is probability sampling

I want to compare age (continuous) and extraversion (continuous).
What is Pearsons r correlation

What is a p-value
200
Rejecting the null hypothesis (Im having way to much fun) when it is TRUE
What is Type I error

the probability of being selected for the sample is unknown
What is Non-probability sampling
200

I'm an avid hiker. I would like to study injuries on the John Muir Trail. I ask my friends to keep daily logs of their activities during their hike. In addition, I ask them to tell their friends to do the same.

What is small sample size

I am studying differences in psychology and bio majors. I cluster students by major, and then randomly select students from psychology and bio.
What is cluster sampling
400
I want to test the difference between ethnicities (5 levels), and self-esteem
What is one way ANOVA
500
the probability that the test correctly rejects the null hypothesis (H0) when the alternative hypothesis (Ha) is true.
What is Power
500
The probability of committing a type II error is .30, what is the statistical power of this study?
What is .70
500
Occurs when a sample is selected in such a way that it is not representative of the entire population and therefore data cannot be generalized.
What is sampling bias
500
I want to test if there are gender differences (categorical) in major (bio or psych; categorical)
