PSYB04H3 Lecture Notes - Lecture 2: Data Visualization, Scatter Plot, Statistical Significance
Document Summary
Hypotheses tested using the scientific method address some of the shortcomings of other methods: caveats, there is good research and there is bad research, all research is probabilistic. Anything that can take on more than one value: vs. a constant, ex. A study shows that students who work up to 20 hours a week outside school have a better gpa than students who don"t work outside school. Variable vs. constant depends on the study: a study shows that part-time students who work up to. 20 hours a week have better gpa"s than full time and part time students who don"t work outside school. Constant often = control variable: ex: in the study of the relationship btw work and gpa, what needs to be held constant, or controlled for , ask yourself: what else might affect this relationship, ex. A study has found that children born to younger parents are less active than children born to older parents.
