3. The dependent variables which are observed and measured by changing independent variables.
5. A method of quantitative data collection that involves observing events, or behaviors, as they occur, and recording their observations.
6. Capable of being tested scientifically, an idea is testable when it logically generates a set of expectations about what we should observe in a particular situation.
