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.

This page is complete for 2017. |

## Outline[edit]

Overviews descriptive statistics and graphical approaches to analysis of univariate data.

- Getting to know a data-set
- Parametric & non-parametric statistics & level of measurement
- Univariate descriptive statistics
- Univariate graphs
- Properties of the normal distribution
- Non-normal distribution

The lecture resources include presentation slides, and sometimes additional notes.
