A study about workplace bullying used multiple regression to model a bullying victim's intention to leave the firm (y) as a function of level of bullying (measured on a 50-point scale, basically quantitative) and perceived organizational support (measured as "low," "neutral," or "high").
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 study about workplace bullying used multiple regression to model a bullying victim's intention to leave the firm
(y) as a function of level of bullying (measured on a 50-point scale, basically quantitative) and perceived
organizational support (measured as "low," "neutral," or "high").
1.
Define dummy variables for organizational support. Use "high" as base level.
2.
Write a first-order model for E(y) as a function of the independent variables that do NOT
incorporate interaction.
3.
Write a first-order model for E(y) as a function of the independent variables that incorporate
interaction.
4.
Write a complete second-order model for E(y) as a function of the independent variables.
In terms of the B's in the model, part (4), give the mean value of intention to leave for a victim who
5.
perceives organizational support as low.
6.
In terms of the ß's in the model, part (4), give the mean value of intention to leave for a victim who
reports a bullying level of 30 points and who perceives organizational support as neutral.
7.
Clearly state the null and alternative hypotheses for the test you can use to determine whether the
terms in the model that allow for a curvilinear relationship between intent to leave and level of bullying are
statistically useful.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe8b2986c-138a-4e9c-92a6-11213a295c30%2F3614ce0a-d6d1-41dd-86e6-9bfd6ae41ec6%2F7r67k2_processed.jpeg&w=3840&q=75)
