Chapter 1 population = the set of all the individuals of interest in a particular study - parameter: a characteristic that describes a population sample = a set of individuals selected from a population, usually intended to represent the population in a research study - statistic: a characteristic that describes a sample descriptive statistics = statistical procedures used to summarize, organize, and simplify data inferential statistics = techniques that allow us to study samples and then make generalizations about the populations from which they were selected independent variable = the variable that is manipulated by the researcher dependent variable = the variable that is observed in order to assess the effect of the treatment attribute (subject) variables = these are characteristics such as age, gender, and intelligence that vary from one individual to another correlational method = two variables are observed to determine whether there is a relationship between them - observe the two variables as they exist naturally for a set of individuals - correlation DOES NOT imply causation experimental method = used to demonstrate a cause-and-effect relationship between two variables - the researcher manipulates one variable by changing its value to determine whether the second variable is effected quasi-experimental design = nonexperimental study that compares groups that were not created by manipulating an independent variable - these groups are instead determined by a participant variable (male vs. female) or a time variable (before treatment vs. after treatment)
