For what is regression analysis used quizlet?

Why is regression analysis used? The goal of regression analysis is to develop a regression equation from which we can predict one score on the basis of one or more other scores. Regression provides a mathematical description of how the variables are related and allows us to predict one variable from the others.

Which of the following describes is the extent to which observations made in a study generalize beyond the specific manipulations or constraints in the study?

External validity is the extent to which observations made in a study generalize beyond the specific manipulations or constraints in the study.

Which of the following threatens the internal validity of an experiment quizlet?

Experimenter bias is a type of artifact and threatens the validity of the measurement, as well as both internal and external validity. The extent to which we can generalize the results of a research study to people, settings, times, measures, and characteristics other than those used in that study.

Which of the following is an example of a history threat quizlet?

Which of the following is an example of a history threat? A televised national disaster that all participants watch (like the 9/11 attacks or the Challenger explosion).

What is regression quizlet?

Regression. A statistical measure that attempts to determine the strength of the relationship between one dependent variable (Y) and a series of other changing variables (independent variables)

What is regression analysis Everfi quizlet?

Regression Analysis. This is a technique that results in developing an equation relating the dependent variable to an independent variable(s). It can be used for both prediction and explanation.

Which of the following research designs is used to determine the causes of behavior that help to explain why?

Which of the following research designs is used to determine the causes of behavior that help to explain why the behavior occurs? Using a non-experimental research design. the behaviors or variables of interest are observed without an intervention or manipulation from the researcher.

What is ex post facto research with example?

Ex post facto study or after-the-fact research is a category of research design in which the investigation starts after the fact has occurred without interference from the researcher.

Which of the following is defined as a threat to internal validity that occurs with a normal physical or mental change in a subject?

Answer: Maturation Feedback: Maturation is a threat to internal validity because if the outcome variable is affected by both naturally occurring physical and mental changes and a treatment the researcher would not be able to determine which had the most effect.

What are internal and external threats to validity?

Internal validity is the degree of confidence that the causal relationship you are testing is not influenced by other factors or variables. External validity is the extent to which your results can be generalized to other contexts. The validity of your experiment depends on your experimental design.

Which of the following represents an example of regression to the mean?

The Sports Illustrated jinx is an excellent example of regression to the mean. The jinx states that whoever appears on the cover of SI is going to have a poor following year (or years). But the “jinx” is actually regression towards the mean. Most players have good games, and they have bad games.

Is statistical regression a threat to internal validity?

What are threats to internal validity? There are eight threats to internal validity: history, maturation, instrumentation, testing, selection bias, regression to the mean, social interaction and attrition.

What is regression in psychology quizlet?

Regression (10) Defense mechanism where individuals faced with anxiety return to an earlier psychosexual stage, or basically, where they return to something comforting. Reaction Formation (10) Defense mechanism where ego unconsciously reverses unacceptable impulses to their opposite.

Which research method will allow researchers to determine the cause of a behavior?

Which research method will allow researchers to determine the cause of a behavior? naturalistic observation.

What data analysis is used to study of a phenomenon to describe the subjective reality of an event?

Phenomenology is used to identify phenomena and focus on subjective experiences and understanding the structure of those lived experiences.

What is quasi-experimental design in quantitative research?

“Quasi-experimental research is similar to experimental research in that there is manipulation of an independent variable. It differs from experimental research because either there is no control group, no random selection, no random assignment, and/or no active manipulation.”

What is the difference between quasi-experimental research and experimental research Brainly?

Differences between true experiments and quasi-experiments: In a true experiment, participants are randomly assigned to either the treatment or the control group, whereas they are not assigned randomly in a quasi-experiment.

What is regression threat?

A regression threat, also known as a “regression artifact” or “regression to the mean” is a statistical phenomenon that occurs whenever you have a nonrandom sample from a population and two measures that are imperfectly correlated.

What is statistical regression internal validity?

Statistical regression (or regression towards the mean) can be a threat to internal validity because the scores of individuals on the dependent variable may not only be the due to the natural performance of those individuals, but also measurement errors (or chance).

What is external validity quizlet?

External Validity. the extent to which the results of the experiment can be generalized or extended to people, settings, times, measures, and other characteristics than those in the original experiment.
