Organizing and Collecting the Information

the thing that is done the worst is the data analysis. It doesn't have to be long but it does have to be intelligent.

State and Trait--a trait is more consistent We want to find traits not states. In order to do it we have to have consistent observation.

Descriptive statistics--are used to communicate the essential characteristics of a data set. (20% of students are female (N=20))

Inferential statistics--go beyond the data to infer to a population based on sample data.

Look up the following terms:

Nominal
ordinal
ratio
