PSYA01H3 Lecture Notes - Lecture 5: Naturalistic Observation, Descriptive Statistics, Normal Distribution
Document Summary
Psya01- lecture 5&6- finding answer begins by finding questions. What do you want to study: theory statement with an underlying reason. Hypothesis: predicts for it to be true. How do you come up with theories: naturalistic observation. There is a social hierarchy in chimpanzees also. Variable anything that can take multiple values: categorical or continuous, categorical distinct categories i. e. eye colour, continuous something you measure i. e. height, how the variable is coded depends on the type of analysis. Statistics describe a set of data to others in an efficient manner: descriptive statistics. Measuring variable across many people and having a lot of data cannot be presented in raw form. Normal distribution what is the most common, in the middle. Mean point that tries to be as close as possible to all other data points: extreme score outlier. Median point that half the data points lie above and half below.
