Identify the factors, levels, and total number of groups for each of the following research examples. State both the number of levels for each factor and describe each in words. A professor suggests that her college students will attend class more if quizzes were given in every class. To demonstrate the need for this change, the professor records the attendance of students (as the number of absences) in morning versus evening classes in which quizzes are given every class or just once a week. She hypothesized that attendance would be highest in the classes with quizzes in each class. Dependent variable: _______________________________________ Factor A: _______________________________________ Levels of Factor A: ______________________________________ Factor B: _______________________________________ Levels of Factor B: _______________________________________ Number of groups: __________

Use the menu to the right of each variable to: - Indicate whether the variable is relevant to the questions we are investigating, and - Identify the variable as either categorical or quantitative. Group of answer choices: - Gender [ Choose ] - Relevant - categorical - Not relevant - categorical - Relevant - quantitative - Not relevant - quantitative - Alcohol [ Choose ] - Relevant - categorical - Not relevant - categorical - Relevant - quantitative - Not relevant - quantitative - Height [ Choose ] - Relevant - categorical - Not relevant - categorical - Relevant - quantitative - Not relevant - quantitative - Cheat [ Choose ] - Relevant - categorical - Not relevant - categorical - Relevant - quantitative - Not relevant - quantitative
