PSY 101 Lecture Notes - Lecture 5: Illusory Correlation, Confirmation Bias, Scatter Plot
Document Summary
Understand the features, strengths, and weaknesses of experiments. The perception of a relationship where none exists. They can look at this and confirm their belief. Theory: whole set of organizing statements everything you know. We can draw flawed conclusions: even with systematic. We are bad statisticians: our ability to understand patterns in the world is limited, we need statistics. A graphed cluster of dots, each of which represents the values of 2 variables. The slope of the points suggests the direction of the relationship. The amount of scatter suggests the strength of the correlation. The investigator manipulates one or more factors ( independent variables ) to observe their effect on some behavior or mental process ( dependent variable ) The experimenter controls for other relevant factors by using random assignment of participants to conditions. Independent variable: the experimental factor that is manipulated, the variable whose effect is being studies.
