✅What is Type III Sum of Squares (SS) in output tables of many tests?

In SPSS, Type III Sum of Squares (SS) refers to a method used in ANOVA (Analysis of Variance) or general linear models (GLM) to partition the variability in the dependent variable among the different effects (main effects and interactions) in your model.

💡In ANOVA or regression, the total sum of squares represents the total variation in the data. It is partitioned into:

1-Model sum of squares (variation explained by the model),

2-Error sum of squares (residuals, unexplained variation),

3-And sometimes, further divided among the individual factors and their interactions.


✅ What does it do? Why is it important to be chosen?

Type III Sum of Squares tests each effect after accounting for all other effects in the model. This means:

🛑It evaluates the unique contribution of each factor or interaction, while holding all other variables constant, and it assumes the model is balanced or uses least squares adjustment for imbalance. This is why we cannot tolerate extremely unbalanced designs when using ANOVA or other related multivariate counterparts like MANOVA.

In SPSS, the Bivariate Correlations menu offers three main types of correlation tests to measure the strength and direction of association between two variables. These are Pearson, Kendall’s Tau-b, and Spearman. Each has different assumptions and is suitable for different types of data and research situations:

One of the most insightfully reflective, thoughtful, and thought-provoking projects I know of in the entire field. So glad to see this outstanding volume, edited by Lee McCallum, Dara Tafazoli, and Ali H. Al-Hoorie, out and 100% openaccess

Dear Colleagues,

Greetings. You might be interested in this monograph, the idea of which came to my mind four years ago after being enlightened by Yin et al.'s (2019) study on the Dispositions towards Loving Pedagogy (DTLP) scale: Instrument development and demographic analysis.

The new scale development and validation might be suitable for EFL/ESL contexts.

Derakhshan, A. (2025). _Loving pedagogy in second and foreign language education: Underlying components, measurement, and ecological systems_. Springer.

This monograph was supported by my national project in China.

Best,

Two Corrections for Cohen's D in SPSS's Tables and their Functions

▶️ Hedge's Correction:


🔹 When the sample size is small (e.g., n=8 in each group), we can use Hedge's Correction. That is a variation of Cohen's d which includes a correction for small sample sizes. This adjustment makes the data analysis more accurate when sample sizes are below 20 per group.


...................

▶️ Glass's delta:


🔹Because group variances were unequal, we calculated Glass's delta instead of Cohen's d. Glass's delta measures effect size using the control group's standard deviation, making it appropriate when variances differ.
