6. Descriptive Statistics
Used to organize and describe the characteristics of a particular data set
This collection of data is sometimes called a data set or just data.
INSTRUCTOR NOTES: The easiest way to remember descriptive statistics is that descriptive statistics are used to describe the data. You could also ask your students, What is the easiest way for you to remember what descriptive statistics are? If they come up with it on their own, they are more likely to remember the mnemonic.

8. Inferential Statistics
Used to make inferences based on a smaller group of data
A sample is a subset of a population.
A population is all of the occurrences with a certain characteristic.
INSTRUCTOR NOTES: It would be a good time to ask your students what the word inference means and how that relates back to what you do in inferential statistics.

9. Inferential Statistics Examples
Take 100 people with depression, and split them up into two groups randomly.
With the first group, give them a sugar pill, and give the second group a new depression drug.
If you find a statistically significant difference, you infer that you would find similar results in the population.
