Calculating sample size
Let's finish up our dive into statistical tests by performing power analysis to generate needed sample size. Power analysis involves four moving parts:
- Sample size
- Effect size
- Minimum effect
- Power
In this exercise, you're working with a website and want to test for a difference in conversion rate. Before you begin the experiment, you must decide how many samples you'll need per variant using 5% significance and 95% power.
