Version: 1.0

Published: 2023-03-15

Author: Muhammed Ali Yilmaz, Osman Dag, Merve Kasikci, Malwane Ananda, Sam Weerahandi

Description: This web-tool enables the researchers to conduct two-way analysis in independent groups designs. There are two-way ANOVA, two-way ANOVA under heteroscedasticity: parametric bootstrap based generalized test and generalized pivotal quantity based generalized test, two-way ANOVA for medians, trimmed means, M-estimators. The web-tool performs descriptive statistics and graphical approaches. Also, researchers have the opportunity to both change the colors of the graphics and download the graphics. Moreover, it assesses variance homogeneity and normality of data in each group via tests and plots.

Usage of the web-tool

            
 (i) load your data set using Data upload tab.

            
 (ii) define response and group variables using Describe data tab.

            
 (iii) check the homogeneity of variance via variance homogeneity tests and normality through normality tests and plots in the Describe data tab. Researchers can also reach the descriptive statistics using this tab.

            
 (iv) compare the groups through two-way tests in independent groups designs and make pairwise comparisons in the Two-way tests tab. 

            
 (v) obtain the graphics by groups in the Graphics tab.

            
 Users can download normality plots (as pdf) from Describe data tab, graphics (as pdf) from Graphics tab. Users can copy and paste all results in text or word files.

            
 If there are missing values in the data, a listwise deletion will be applied and a complete-case analysis will be performed.
