Document Summary
Psyb30 lecture 2: personality assessment, measurement, and research. Scientific method: describe how to make and test observations, draw conclusions, minimize errors, publish results, tools. Theories they help form the basis of your hypotheses. Used to determine causality whether one variable causes another two key requirements: Manipulation of variables experimenter manipulates independent variable and measures effects on dependent variable. Ensuring that participants in each experimental condition are equivalent to each other accomplished through random assignment. Correlation is a statistical procedure for determining whether there is a relationship between two variables. Designed to identify what goes with what in nature, and not designed to identify causal relationships. Major advantage is that it allows us to identify relationships among variables as they occur naturally. Correlation coefficient varies from -1 (perfect negative relationships) through 0 (no relationship) to +1 (perfect positive relationship: positive: as one variable increases, the other one increases as well, negative: as one variable increases, the other one decreases.
