A guidance counselor wants to determine if there is a relationship between a student's number of absences, x, and their grade point average (GPA), y. The data that were collected are displayed in the scatterplot and the least-squares regression line was calculated. One student with 2 absences has a GPA of 1.8. This point is circled on the graph. What effect đoes the point standard deviation of the residuals? O This point will increase the value of the standard deviation of the residuals because it has a large positive residual. O This point will increase the value of the standard deviation of the residuals because it has a large negative residual. O This point will not affect the value of the standard deviation of the residuals because it has a large positive residual. GPA and Absences 4.8 4.4 4.0 O This point will decrease the value of the standard deviation of the residuals because it has a large negative residual. 36 3.2 2.8 24 284 0 NN NN GPA

Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
