If you’re reading this post, you already know how CRO (“conversion rate optimization”) can help you increase revenues and create better customer experiences. The problem now is: how do you decide what to test?
Confidence Interval: A range of values calculated such that there is a known probability that the true mean of a parameter lies within it.
Confidence Level: The percentage of time that a statistical result would be correct if you took numerous random samples.
Margin of Error: An expression for the maximum expected difference between the true population parameter and a sample estimate of that parameter.
Sample Size: The number (n) of observations taken from a population through which statistical inferences for the whole population are made.
