Parameter
What does the I stand for? (SPINE Statistics)
Interval estimates
What does the N stand for? (SPINE Statistics)

What does the E stand for? (SPINE Statistics)
Estimation
How do you know if there is sampling error? (SPINE Statistics)
The mean sample and mean total population should be the same, if not there is sampling error
What is sampling variation? (SPINE Statistics)
Lots of random samples and you estimate the parameter, they may have different values
What is standard error? (SPINE Statistics)
Measure of the statistical accuracy of an estimate, which is equal to the standard deviation
What is a confidence interval? (SPINE Statistics)
Contains the true population value of the parameter in 95% of samples
What is the chain of events to form an experimental hypothesis? (SPINE Statistics)
- Generate hypothesis
- Specify significance
- PICK SAMPLING DISTRIBUTION
- Randomly sample
- Calculate probability
- Compare to alpha level
What is the chain of events to form an null hypothesis? (SPINE Statistics)
- Generate hypothesis
- Specify significance
- CALCULATE SAMPLING SIZE
- Randomly sample
- Calculate probability
- Compare to alpha level
When do we reject our hypothesis? (SPINE Statistics)
When p=≤𝝰
When do we accept our hypothesis? (SPINE Statistics)
When p=≥𝝰
What is the effect size? (SPINE Statistics)
A simple way of quantifying the difference between two groups
What is CohensD? (SPINE Statistics)
The difference between means, divided by the SD
