Finding the Right Sample Size for One-Sample T-Tests: Examples and Applications
When planning a study to check if a sample’s average significantly differs from a known reference value, it’s essential to choose the right sample size. With a sample size that’s too small, there’s a risk of missing a significant difference (underpowered study). A sample that’s too large, however, can lead to wasted time and resources. Using G*Power software, researchers can calculate the ideal sample size to reliably detect meaningful differences.… Click to Read the Full Article

How to Choose the Right Sample Size for Your Correlation Studies Using G*Power
When planning a research study, especially one that looks at the relationship between two things, it’s important to choose the right number of people to include in the study. If the sample size (number of participants) is too small, it can be hard to see if there’s actually a relationship between the two variables you’re studying. But if the sample size is too large, you might waste time and resources.… Click to Read the Full Article

Satisfaction Survey of NEU’s Science Fair
Satisfaction survey of a Science Fair was examined using Two-Way ANOVA. The dependent variable (AVG) indicated a respondent’s mean score on a 7-item, 5-point Likert scale (1-Very Poor, 2-Poor, 3-Satisfactory, 4-Good, 5-Excellent). The seven items rated were Venue/place (VENUE), Inventiveness (INVENT), Commercial Viability (IMPACT), Educational Value (EDUC), Audio-Visual Presentation (PRESENT), Organization (ORGANIZE), and Overall Experience/Satisfaction (OVERALL). The independent variables were GENDER (MALE, FEMALE) and GROUP (STUDENT – student, EXHIB -… Click to Read the Full Article

Binary Logistic Regression Modeling for Predicting Potential Offenders of Discipline Rules in an Integrated School
Two binary logistic regression models (Model C and Model D) were selected from four alternative models developed to determine if a combination of gender, religion, and grade level could significantly predict potential violators of school discipline rules. Grades 7 to 12 students enrolled during the Academic Year 2022-2023 in a private Integrated School in Quezon City, Philippines composed the target population of the study. The 753 sample cases used was… Click to Read the Full Article

A Satisfaction Survey Analyzed as Nonparametric Mixed ANOVA Design with Aligned Rank Transformation
Satisfaction survey data from a University’s Science Fair was analyzed using nonparametric Mixed ANOVA (with aligned rank transformation). The dependent variable was the satisfaction score and the independent variables (between-subjects factors) were GENDER (male, female) and GROUP (student, exhibitor, and faculty). The variable ITEM (with seven items) was the within-subjects factor. A seven-item, 1-5 Likert scale (1-Very Poor, 2-Poor, 3-Satisfactory, 4-Good, 5-Excellent) questionnaire was administered to 162 respondents, randomly selected… Click to Read the Full Article

Sensitivity of a 2 x 3 ANOVA on Normality and Homogeneity of Variances Assumptions
This study explored the differential results of parametric test and nonparametric test as applied to a 2 x 3 ANOVA. The data used in this study were those of NEU’s 2018 Science Fair Satisfaction Survey with the mean satisfactory rating (AVG) as the dependent variable for the original or untransformed data. The AVG for the six cells of the factorial design exhibited varying degree of negative skewness (-0.562 to -1.293).… Click to Read the Full Article
