Study Notes
Variable Types
- Nominal variables: Categories have no inherent order or relationship.
- Ordinal variables: Categories have a ranked order, but the intervals between them aren't equal.
- Interval/ratio variables: Categories have a ranked order with equal intervals, and a true zero point.
Relationships Between Variables
- Correlation: Variables change in relation to each other.
- Causation: One variable directly causes the change in another.
- Spurious relationships: False association between variables, arising from a third, unseen factor.
Research Designs
- Cross-sectional: Data collected at a single point in time, like a "snapshot."
- Longitudinal: Data collected over an extended period to track changes.
- Trend study: Tracks changes in a general population, not necessarily the same individuals.
- Panel study: Tracks changes in the same individuals over time.
Research Purposes
- Descriptive: Describes characteristics of messages and contexts.
- Explanatory: Explains the meaning and effects of messages.
- Predictive: Predicts future behavior based on messages.
