![]() The sampling distribution of events that have two equally likely outcomes. ![]() In ANOVA, a measure of the variability of the dependent variable across the experimental conditions.Įxperiments in which the comparison of the scores on the dependent variable is between the participants in the different levels of the independent variable and each individual is in only one level. The probability of making a Type 2 error. Research designed to study the thoughts, feelings, and behavior of human beings and animals. Measured variables designed to directly measure an individual’s actions. The specific set of observations that are recorded in systematic observational research. Research designed to answer fundamental questions rather than to address a specific real-world problem.ĭesigns in which the dependent measure is assessed both prior to and after the experimental manipulation has occurred. Research that uses existing records of public behavior as data.Ī measure of central tendency equal to the sum of the scores on the variable divided by the sample size (N).Īspects of the research methodology that may produce confounding.Ī threat to internal validity in longitudinal research when participants who stay in the research are different from those who drop out.Ī visual display of a frequency distribution.Īn initial measurement of the dependent variable in a before-after research design. Research designed to investigate issues that have implications for everyday life and to provide solutions to real-world problems. The possibility that a confounding variable, rather than the independent variable, caused the differences in the dependent measure.Īn analysis in which the means of the dependent variable in the different experimental conditions are adjusted or controlled for the influence of one or more quantitative variables on the dependent variable.Ī statistical procedure designed to compare the means of the dependent variable across the conditions of an experimental research design.Ī table that displays the ANOVA calculations including F and its associated p-value. The probability of making a Type 1 error. A research design in which measurements are made before, during, and after the change in the independent variable occurs.Īcquiescent responding (yeah-saying bias)Ī form of reactivity in which people tend to agree with whatever questions they are asked.
