Chapter 5

 

Hypotheses

Purpose of Chapter

 

Building on the emphasis on explanation, this chapter will:

 

  • define and describe what a hypothesis is, and relate hypotheses to theory;
  • demonstrate how to state hypotheses;
  • define what a null hypothesis is, and describe its role in the research process.

 

 

Notes on Chapter 5 Text Material

 

Although students have already been introduced to the idea of relationships between variables, the text has not yet shown them how to postulate such relationships in the form of hypotheses. In this chapter, students will learn how to formulate hypotheses for various situations and they will see how hypotheses are related to theory. They will also learn about the role of the null hypothesis.

 

This chapter gives students quite a bit of nuts-and-bolts instruction on stating hypotheses and null hypotheses. This also includes discussion of how to state hypotheses for relationships between dependent variables and independent variables while controlling for a possible antecedent or intervening variable.

 

 

Notes on the Chapter 5 Worksheet Section

 

The worksheets will give the student experience and understanding in:

 

  • distinguishing between dependent variables and independent variables
  • stating hypotheses
  • stating null hypotheses

 

The questions will also give students additional exposure to cross-tabulation tables prior to the more in-depth discussion in Chapter 9. Also, students will do a preliminary testing of a null hypothesis by looking for patterns in cross-tabulation tables, by examining similarities in maps, and by using correlation coefficients loosely. Later—starting in Chapter 10—they will more fully test the null hypothesis.

 

 

 

 

Sample Exam Questions

 

Fill-in

 

A (an) ______________________________ is a testable statement of a relationship derived from a theory. (HYPOTHESIS)

 

True/False

 

A null hypothesis states that there is no relationship between the variables in a hypothesis.

 

Answer: TRUE

 

We actually test the null hypothesis rather than the hypothesis.

 

Answer: TRUE

 

Strictly speaking, a theory can never be proven.

 

Answer: TRUE

 

In a negative relationship, there is no relationship between the dependent variable and the independent variable.

 

Answer: FALSE

 

In stating hypotheses, the terms direct and positive mean the same thing.

 

Answer: TRUE

 

Multiple-choice

 

Which of the following is not required of a hypothesis?

 

  1. A hypothesis must be testable.
  2. A hypothesis must state a relationship between variables.
  3. A hypothesis is derived from a theory.

*D.  A hypothesis must be based on common sense.

 

Which of the following is NOT a properly-stated hypothesis?

 

*A.  There is a positive relationship between support for capital punishment and gender.

  1. Men are more supportive of sexual equality than women are.
  2. There is a negative relationship between support for racial equality and age.
  3. There is an inverse relationship between political tolerance and racism.

 

A political researcher expects that higher income leads to higher political trust. At the same time, the researcher expects that part of the relationship between income and political trust might be due to the effects of education on both income and political trust. Which of the following would be the hypothesis in this situation?

 

  1. There is a negative relationship between income and political trust.

*B.  There is a positive relationship between income and political trust while controlling for education.

  1. There is no relationship between income and political trust while controlling for education.
  2. There is a negative relationship between income and political trust while controlling for education.

 

 

 

 

Short answer

 

State a hypothesis to express the relationship between support for capital punishment and support for gun control.

 

Answer: There is a positive relationship between support for capital punishment and support for gun control or There is a negative relationship between support for capital punishment and support for gun control.

 

State the null hypothesis for the hypothesis above.

 

Answer: There is no relationship between support for capital punishment and support for gun control.

 

State a hypothesis to express the relationship between support for sexual equality and gender.

 

Answer: Males are more supportive of sexual equality than females are or females are more supportive of sexual equality than males are.

 

State the null hypothesis for the hypothesis above.

 

Answer:  There is no relationship between support for sexual equality and gender.

 

 

Essay

 

Why is it that we can never absolutely prove a theory?

 

Suppose that, on the basis of a theory concerning the causes of political alienation, a political researcher hypothesizes that political alienation will be greater among people engaged in occupations that involve very little social contact.  The research results are in accord with this hypothesis.  What conclusions would we draw about the status of the null hypothesis (reject or not reject?) and the correctness of the theory?
