You have chosen the Chi-Square Test of Independence 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 Proportional Variable of Interest. Your variable of interest is proportional, meaning it is usually a percentage or ratio.
- Proportional Variable of Interest: You chose Two Group Variables. You only have one group of samples, and you would like to compare that sample with a population average.
- Two Group Variables: You chose More Than Two Options. Your group variable can only take on two values. For example, did the customer buy your product (yes/no), what is the customers gender (male/female), etc.
- More Than Two Options: 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 women (group 1) and randomly sampled men (group 2). Another example would be randomly sampled people with blue eyes (group 1) and randomly sampled people with brown eyes (group 2).
- Independent Samples: You chose More Than 10 In Every Cell. This means that for all of the options of all of your group variables, you have more than 10 subjects or participants. Another way to say this would be that every cell in your contingency table is greater than 10.
