Lecture 03: Descriptives & graphing

Resource type: this resource contains a lecture or lecture notes. |

This is the third lecture for the Survey research and design in psychology unit of study.

## Outline[edit]

Overviews descriptive and graphical approaches to analysis of univariate data.

- Steps with data
- How to approach data
- Parametric & non-parametric statistics & level of measurement
- Properties of the normal distribution
- Non-normal distribution
- Univariate descriptive statistics
- Univariate graphs

The lecture resources include presentation slides, audio and video recordings, and additional notes.
