| 2 Types of Statistics | Descriptive and Inferential |
| 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 |
| Continuous Data | Values can occur at any point along scale; infinite number of values. (e.g., decimals) |
| Discontinous Data | Values occur at specific points along scale; countable values. |
| 4 Scales of Measurement | Nominal, Ordinal, Interval, Ratio. |
| Scales of Measurement: Nominal | Qualitative, categorical data; discontinuous. |
| Scales of Measurement: Ordinal | Rank ordering. |
| Scales of Measurement: Interval | Intervals between ranks are measurable and meaningful, but there is NO TRUE ZERO POINT. (e.g., IQ test) |
| Scales of Measurement: Ratio | Combination of Nominal, Ordinal, and Interval with a TRUE ZERO POINT. |
