Numerical data involves distinct labels, while categorical data consists of measurable quantities.

• True

• False

• Both B and D

• All statements are correct

Which of the following does the bivariate analysis: categorical and categorical not use?

• Stacked Column Chart

• Combination Chart

• Chi-Square test

• Dot plot
