Enter a value for α (default is.05): Enter a value for desired power (default is.80): The sample size (for each sample separately) is. Collecting Responses. Now that you know how many responses you need, work backwards to know how many people you need to reach or send it out to. A response rate of 20% is good while a response rate of 30% is above average. Take your needed sample size and divide it by your expected response rate percentage.
