A researcher predicts that people with higher levels of racism (measured on a scale of 1 to 8, with higher numbers meaning more racism) will offer a smaller starting salary to a potential employee who is a racial minority. Given r = –.62, MX = 5.26, SX = 2.33, MY = 350.23, and SY = 25.03, which of these best characterizes the relationship between racism and salary offers? a. A one-point increase in racism is associ
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.

a. A one-point increase in racism is associated with a 0.06-dollar decrease in starting salary offers.
b. A one-point increase in racism is associated with a 6.66-dollar decrease in starting salary offers.
c. A practically significant predictive relationship does not exist between these variables
d. A one-point increase in racism is associated with a 2.33-dollar decrease in starting salary offers
