Week 8 Assignment

For this assignment you will use the Week_08_Assignment_Data.csv file, which can be found on the Week 8 Assignment page in Canvas. This is a hypothetical dataset. Assume these data were collected from a representative sample of students enrolled in one large introductory statistics course. Prior to taking a quiz on data visualization students complete a survey measuring their self-efficacy as it relates to data visualization. A researcher wants to use students’ self-efficacy scores to predict their quiz scores.

The dataset includes the following variables:

·       id: A unique nominal-level identification number assigned to each student

·       quiz_score: Score on a quiz measuring knowledge of data visualization

·       self_efficacy: Composite score on a measure of self-efficacy as it relates to data visualization

Criteria:

·       Construct a scatterplot in JASP

·       Construct a plot of residuals versus predicted values in JASP

·       Construct a graph in JASP that can be used to evaluate the normality of residuals

·       Evaluate graphs to determine if the assumptions of simple linear regression have been met

·       Construct a simple linear regression model using JASP

·       Interpret the statistical significance of a simple linear regression model

·       Write one sentence in APA style summarizing the results of the simple linear regression model
