Tutorial SPSS Uji Asumsi Klasik : Uji Normalitas, Uji Multikolinearitas dan Uji Heteroskedastisitas

Summary

In this tutorial video, Kartika guides viewers through the process of conducting classical assumption tests in SPSS, focusing on normality, multicollinearity, and heteroskedasticity. She provides step-by-step instructions on setting up data and interpreting results, including histogram analysis, P-P plots, and the Kolmogorov-Smirnov test for normality. The video explains how to detect multicollinearity using Variance Inflation Factor (VIF) and tolerance values, as well as assessing heteroskedasticity through scatterplots. With clear explanations and practical examples, this video is a valuable resource for anyone interested in statistical analysis.

Takeaways

• 😀 Ensure to subscribe and turn on notifications for the channel before diving into the video content.
• 📊 Start by copying your respondent data into SPSS and accessing both Data View and Variable View.
• 🔍 In Variable View, define your variables clearly, labeling them appropriately for easy identification.
• 📈 Conduct normality tests using multiple methods, including histogram analysis and P-P plots.
• 📝 A variable is considered normally distributed if the significance level from the Kolmogorov-Smirnov test is greater than 0.05.
• 🔗 For multicollinearity detection, utilize the Variance Inflation Factor (VIF) and ensure it is below 10.
• ✅ Tolerance values should be above 0.1 to confirm no multicollinearity exists between variables.
• 📉 Use scatter plots to assess heteroscedasticity, ensuring that points are randomly dispersed without forming patterns.
• 🛠️ Understanding the assumptions of classical tests (normality, multicollinearity, heteroscedasticity) is crucial for accurate statistical analysis.
