Descriptive Statistics | Describe, organize, and summarize data set; show characteristics of sample. |
Inferential Statistics | Describe relationships in data set; determine "chance factor." |
Two types of Data (for the DV) | Continuous and Discontinuous |

Scales of Measurement: Nominal | Qualitative, categorical data; discontinuous. |
Scales of Measurement: Ordinal | Rank ordering. |
