Document Summary

Regression: regression is a statistical method used to analyze the relationship between a dependent variable and one or more independent variables. It is used to predict the value of the dependent variable based on the values of the independent variables. Types of regression: simple regression involves a single independent variable and a dependent variable. The purpose of this method is to establish a relationship between the two variables, and to use the independent variable to predict values of the dependent variable. Multiple regression involves two or more independent variables and a dependent variable. The purpose of this method is to determine the relationship between the dependent variable and the independent variables, and to use those variables to predict values of the dependent variable. Linear regression is a type of regression analysis where the relationship between two variables is modeled as a linear function.

Part 1: Identifying Independent Clauses

Highlight or bold the independent clauses in the paragraph below. Some independent clauses are interrupted by dependent clauses, so you'll highlight around the dependent clause. For example:

Jenny discussed the work schedule with her manager who suggested she work extra hours this week.

Later Jenny decided despite the advice that she would work her regular schedule

Why do I want you to identify independent clauses? 1. You need to write in full sentences, not fragments. 2. Most comma rules are about setting off nonessential clauses from the independent clause.

In the above two sentences, commas should be where the independent clauses begin/end:

Jenny discussed the work schedule with her manager, who suggested she work extra hours this week. Later, Jenny decided, despite the advice, that she would work her regular schedule.

Our class novel by Octavia Butler will soon be made into a television series. I have recommended it to many friends many of whom have read it. In past sections of the class students have enjoyed it. Although it can be hard to read about violence and cruelty Butler's novel takes us into part of our history a part we should not look away from. Some people believe we should ignore the past if it makes us feel uncomfortable however I believe that we must confront the past to make our future better. The people I most admire in the world agree with this fundamental idea.

Why is competition considered to be a density-dependent factor?

B. Competition is a density-independent factor.

C. It isn't affected by the amount of individuals or resources in an area.
