Simple Regression

Multiple Regression

In regression analysis, what term is used to describe the variable that is being predicted by the model?

A clinical researcher uses regression analysis to investigate whether a patient's average hours of sleep per night can predict their subsequent score on a depression scale. Match each component of this study with its role in the regression model.

A researcher uses regression analysis to predict 'life satisfaction' based on 'social connectedness.' In this model, 'life satisfaction' is the criterion variable. If the researcher reverses the model to use 'life satisfaction' to predict 'social connectedness,' 'life satisfaction' remains the criterion variable because it represents the ultimate psychological outcome of the interaction.

A researcher is evaluating a peer's study designed to predict 'Academic Resilience' based on 'Level of Social Support'. To evaluate whether 'Academic Resilience' is appropriately categorized as the outcome (criterion) variable, arrange the following steps in the correct logical sequence of evaluation.

Suppose you are designing a two-stage research project to investigate the factors influencing educational success. In Stage 1, you construct a regression model to predict a child's 'Academic Readiness' ($AR$) based on their 'Parental Income' ($PI$). In Stage 2, you expand this design to use that same 'Academic Readiness' ($AR$) to predict the child's likelihood of 'High School Graduation' ($HSG$). To correctly construct these models within your research plan, how must the role of $AR$ be designated in each stage?

In regression analysis, the criterion variable is the variable that is being predicted by the model.

A psychologist uses a regression model to estimate an individual's level of social anxiety based on their score on a personality test. In this model, the level of social anxiety is the _____ variable.

A developmental psychologist wants to design a regression analysis to determine if the number of hours children spend reading per week can predict their vocabulary size. Match the components of this research study to their appropriate roles.

A researcher is conducting a study using regression analysis to examine how levels of daily stress predict sleep quality. If the researcher decides to restructure the model to investigate whether sleep quality instead predicts daily stress levels, the variable 'daily stress' shifts from being the outcome variable (or criterion variable) to being the _____ variable.

A research evaluator is reviewing a proposed regression study that intends to predict a participant's 'cognitive fatigue' based on their 'screentime hours'. Order the evaluator's steps to verify and justify whether 'cognitive fatigue' is correctly designated as the outcome (criterion) variable rather than the predictor variable in this model.
