The article discusses how to measure the relationship between two categories in tables, like in surveys. It looks at different ways to show this relationship, depending on the type of data and table size. The researchers used a measure called Cramer’s V2 to analyze the data. They also provided tables to help determine the minimum sample size needed for accurate results. By using data from a survey, they showed how to calculate these measures and sample sizes. This information is important for studies in behavioral sciences to make sure they have enough data for their analysis.
