Question

Which of the following is an example of a one-way ANOVA test?

Answer 1

Solution:

To use one way ANOVA, we must have one dependent variable and at least 3 independent variables.

Option a) has only 2 independent variables, thus option a) is incorrect.

Option b) has one dependent variable: " Number of Hours of Sleep" and 3 independent variables: "Teenagers", "Adults" and "Senior Citizens".

Thus option b) is correct.

Option c) has two dependent variables: " Number of Hours of Sleep" , "Average GPA", and 3 independent variables: "Middle School", "High School" and "College Student". Thus we must use Two Way ANOVA instead of one way ANOVA, thus option c) is incorrect.

Option d) has one dependent variable: " Number of Hours of Sleep" and 2 independent variables: "Children" and  "Teenagers". Thus we can not use One way ANOVA. thus option d) is incorrect.

Thus correct answer is: option b)
