A researcher conducted a two-way ANOVA and found the following results for one of the main effects, F(2, 347) = 9.84, p = 0.005, η² = 0.010, observed power = .87. How can the researcher interpret the effect size? Give an example of how a relationship study in a busin...

The term "statistical significance" often pops up in research and data analysis, but what does it actually mean? At its core, statistical significance is a way to express how confident you can be that your findings are not just a fluke. It’s like a stamp of reliability on your results,...
Correlation does not equal causation. While quantitative research can identify relationships between variables, establishing definitive cause-and-effect links is challenging. Other factors may influence the observed relationship, making it difficult to isolate the true cause. ...
In hypothesis testing, what does F =1 mean in ANOVA? If an ANCOVA is a refinement of an ANOVA, why not use it constantly and never use an ANOVA? What is the F critical value for α = .05? Is this ANOVA significant? What are the assumptions of ANOVA, and what tests are done for...
