In qualitative research, theory is which of the following?
 
  A) A method to test hypotheses
  B) A tool to direct the research project
  C) A product of the research
  D) A way to test relationships between two different groups

Question 2

Why is it most appropriate to compute a chi-square (2) when comparing frequency of gender (male/female) and smoking status (smoker/nonsmoker)?
 
  1. Gender and smoking status are both nominal level variables in this example and a chi-square requires nominal level data.
  2. Gender and smoking status, as defined in this case, are both ordinal level data and a chi-square requires ordinal level data.
  3. Chi-square is used in any research question where the independent variable is grouped according to gender.
  4. An ANOVA is the most commonly used test with nominal/nominal level data.

Answer to Question 1

C
Feedback:
A theory is an explanation of some aspect of the study. In qualitative studies, theory often is the product of the research. It is not used to test hypotheses, to direct the research project, or to test relationships between two different groups.

Answer to Question 2

1
Rationale 1: Chi-square is probably the most commonly used statistic with nominal level data.
Rationale 2: Chi-square requires nominal level data, which are the type of data presented in this scenario.
Rationale 3: A t test for independent samples can be calculated with gender as the grouping or independent variable and an interval level score as the dependent variable.
Rationale 4: ANOVA requires nominal level independent or group data but interval or ratio level data for the dependent variable.
