Document Summary

Psyc 218: populations: complete sets of objects that we"re studying, that we"re interested in make statements about. The way we are going to do this is by using samples and subsets of the population. The techniques used are used to draw inferences about the population to make generalizations of populations: variables: properties and characteristics that objects have that take different variables. Observational studies: research that involves the scientist simply observing measurements going on in the world. Parameter estimation: estimating a population value on the basis of a sample. Correlational research: statistical techniques (correlation and regression) used to describe the relationships between and among variables. Experiments: determining if one manipulated variable is changing another variable. Types of statistics: descriptive: describing or characterizing obtained data. Inferential: how to perform an analysis that lets us preform an inference that effects the whole population just on the basis of a sample obtained.
