PSYB04H3 Lecture Notes - Lecture 2: Scatter Plot, Homicide, Visual Acuity
Document Summary
Three claims (what the research is trying to say, what they think their study is about), four validities (ways in which research can be valid or invalid) Anything that can take on more than one value (a constant is the opposite and it doesn"t change); e. g. how many miles you have to travel to get to work, how tall people are. There"s also positive mood induction music and negative mood induction music. Conceptual construct (often high-level construct); something that you can"t measure directly; e. g. personality is a construct because it can"t be measured directly, can"t put someone on a scale and measure their personality. One variable being counted (rate, degree, number) Could include a comparison or involve calculation. E. g. murder rate, baseball stats; homicide rates for di erent countries can all be on a graph but each would be a frequency claim, even though it"s scaled to 1000 people of the pop.
