You have chosen the Kruskal-Wallis One-Way ANOVA with your answers to the Choose Your StatsTest questions. To summarize how you got here:
- Choose Your StatsTest: You chose Difference. You are looking for a statistical test to compare your sample with another sample or a population average.
- Difference: You chose Continuous Variable of Interest. Your variable of interest is continuous, meaning it can take on basically any value.
- Continuous Variable of Interest: You chose Many Samples Tests (3+ groups). You have 3+ groups of samples, and you would like to compare the three groups on your variable of interest to see if they are statistically significantly different.
- Many Sample Tests (3+ groups): You chose Independent Samples. This means the two samples or groups you are comparing are not dependent on each other or influenced by each other. For example, independent groups would be randomly sampled young women (group 1), randomly sampled middle-aged women (group 2), and randomly samples elderly women (group 3). Another example would be randomly sampled people with blue eyes (group 1), randomly sampled people with brown eyes (group 2), and randomly sampled people with green eyes (group 3).
- Independent Samples: You chose Skewed Variable of Interest. Your variable of interest is not normally distributed, but rather leans to the left or right and most of the data does not reside in the center.
