Question: What type of summary or comparison analysis are you performing?
To determine the appropriate statistical method for summarizing or comparing mixed data without focusing on relationships, consider whether you are interested in descriptive analysis or hypothesis testing.
Descriptive Analysis
If your goal is to summarize and describe your data without testing specific relationships, select this option.
- Descriptive Statistics
- Use descriptive statistics to calculate measures such as mean, median, mode, variance, and standard deviation. These measures provide a clear overview of the central tendency and variability of your data.
Hypothesis Testing
If your goal is to test hypotheses about your data, select this option to explore methods that assess differences between groups.
- One-Way ANOVA
- Use one-way analysis of variance (ANOVA) to compare means among three or more groups based on a single independent variable. This method helps determine if at least one group mean is significantly different from the others. It assesses the relationship between one categorical predictor and a continuous outcome, making it suitable for experiments or observational studies with a single factor.
- Two-Way ANOVA
- Use two-way analysis of variance (ANOVA) to compare means among groups based on two independent variables. This method not only helps determine if there are significant differences among group means but also assesses the interaction effect between the two factors. It is useful for studies that examine the combined effect of two factors on a continuous outcome.
