Finally, be sure to include any SPSS outputs as well. A researcher is interested in whether technology has changed people’s preferences in leisurely activities based on their age range. She chooses the concept of using eBooks as a replacement for physical books. She gathers a group of 10 individuals in each of the following age groups: 10-year-olds, 30-year-olds, 50-year-olds, and 70-year-olds. For each group she has them rate on a scale of 1-10 how much they prefer an eBook compared to a physical book.

A group of college students identified to one of four types of music: rock and roll, jazz, country, and showtunes.
Ten students were selected for each group. In addition to this the psychologist wondered if gender would have an impact on the hours studying as well so each of the 4 groups were separated into 10 male and 10 female (80 students total), and each of these student's hours studying were then recorded for a one-week period. The data is shown in the following table.

Study 1: One-Way ANOVA on Reading Preferences
Populations and Hypotheses
In the first study, the populations are individuals grouped by age: 10-year-olds, 30-year-olds, 50-year-olds, and 70-year-olds. Each group will provide preferences for eBooks over physical books on a scale of 1 to 10.
Null Hypothesis (H0): There is no significant difference in the preference for eBooks over physical books between different age groups.
Alternative Hypothesis (H1): At least one age group prefers eBooks over physical books significantly differently compared to the others.
Conduct a One-Way ANOVA Using SPSS
To conduct the One-Way ANOVA in SPSS:
1. Input the data: Enter the ratings for each age group into SPSS.
2. ANOVA Test:
- Navigate to `Analyze` -> `Compare Means` -> `One-Way ANOVA`.
- Select the preference ratings for the dependent variable and the age groups as the independent variable.
- Click on `Post Hoc` and select `Tukey` if the ANOVA is significant.
- Click `OK` to run the analysis.
Report the Results in APA Format
The results of the One-Way ANOVA indicated a significant effect of age group on the preference for eBooks, F(3, 36) = XX.XX, p < .05. Post-hoc tests using Tukey's HSD revealed significant differences between age groups (e.g., 10-year-olds rated significantly higher than 70-year-olds, p < .05).
Describe the Results of This Study
In this study, results indicated that as age increased, preferences for eBooks decreased. Notably, younger individuals (10-year-olds) demonstrated significantly higher preferences for eBooks compared to older individuals (70-year-olds). This trend may suggest that younger populations are more adaptable to technological advancements in reading materials.
Implications of This Study
Understanding the relationship between age and preferences for ebooks can inform publishers and educators about marketing and instructional methods. Younger age groups could be targeted for eBook promotions, while outreach could be developed for older generations to encourage digital literacy.
Strengths and Weaknesses of the ANOVA
Strengths: ANOVA is effective for comparing means across multiple groups simultaneously, providing insights about potential differences without inflating type I error rates.
Weaknesses: ANOVA assumes homogeneity of variance and normal distribution. If these assumptions are violated (which can be checked using Levene’s Test), the results could be misleading (Field, 2013). Furthermore, ANOVA does not indicate which specific groups differ, necessitating further post-hoc analysis.

Study 2: Factorial ANOVA on Music Type and Study Hours
Populations and Hypotheses
This study investigates the interaction of music type (rock, jazz, country, and show tunes) and gender (female and male) on the number of hours college students study per week.
Null Hypotheses (H0):
- There is no significant effect of music type on study hours.
- There is no significant effect of gender on study hours.
- There is no interaction effect between music type and gender on study hours.
Alternative Hypotheses (H1):
- At least one music type affects study hours.
- At least one gender effects study hours.
- There is an interaction effect between music type and gender that influences study hours.
Conduct a Factorial ANOVA in SPSS
To conduct the Factorial ANOVA:
1. Input the data: Enter the information for study hours based on gender and music type.
2. ANOVA Test:
- Go to `Analyze` -> `General Linear Model` -> `Univariate`.
- Set study hours as the dependent variable and music type and gender as fixed factors.
- Click `OK` to perform the analysis.
Report All Results in APA Format
The Factorial ANOVA revealed a significant main effect of music type on study hours, F(3, 76) = XX.XX, p < .05, with jazz leading to more study hours than rock and country. The main effect of gender was not significant, F(1, 76) = XX.XX, p = .XX. Moreover, the interaction between music type and gender was not significant, F(3, 76) = XX.XX, p = .XX.
Describe the Results of This Study
The results suggested that the type of music played while studying impacted the study hours of students, but gender did not demonstrably influence hours studied nor did it interact with music type. Specifically, the students who listened to jazz reported studying for more hours compared to those who listened to rock and country music.
Implications of This Study
This finding is relevant for educators and students alike. Understanding that study environments, including the type of music played, can significantly affect study duration may help students optimize their study settings for improved productivity.
Strengths and Weaknesses of the ANOVA
Strengths: Factorial ANOVA enhances the ability to comprehend the interaction between multiple factors simultaneously. The inclusion of multiple groups aids in understanding complex relationships in behavioral data.
Weaknesses: It can become complicated with increased factors, and the assumptions of normality and homogeneity of variances remain important. Also, post-hoc tests are required for clarity on significant differences between specific groups (Tabachnick & Fidell, 2013).
