Document Summary
Constant unit distance (can operate with +-*/) Scales: nominal categorical, ordinal categorical, interval continuous, ratio continuous. Only with these we can do the multiplication/division. Inferential statistics: sample population (students in class uci students, estimate parameter (observed mean gpa of our class true value of mean gpa in uci, estimator: the method to operate inference, null hypothesis: You can set up a hypothesis to test, but for consistency and power, the null hypothesis is usually the differences between two or more population parameters are zero , or no differences exist between groups in an experiment . Questionnaire design: open ended, fixed alternative (close ended, likert-type items: each item is given a certain weight and are summed together, semantic differential.
