# Your StatsTest Is The Paired Samples Z-Test

You have chosen the Paired Samples Z-Test with your answers to the Choose Your StatsTest questions. To summarize how you got here:

1. Choose Your StatsTest: You chose Difference. You are looking for a statistical test to compare your sample with another sample or a population average.
2. Difference: You chose Continuous Variable of Interest. Your variable of interest is continuous, meaning it can take on basically any value.
3. Continuous Variable of Interest: You chose Two Sample Tests (2 groups). You have two groups of samples, and you would like to compare the two groups on your variable of interest to see if they are statistically significantly different.
4. Two Sample Tests (2 groups): You chose Paired Samples (repeated measurements). This means that you have two dependent groups, which usually means multiple measurements for a single group.
5. Paired Samples (repeated measurements): You chose Normal Variable of Interest (and Population Variance Known). Your variable of interest is normally distributed, meaning it is bell shaped and most of the data is in the center. Additionally, you know the population variance (the spread of the data for your variable of interest) and your sample size is greater than 30.
