How do I calculate the sample size for my study?
An example of an AI chatbot conversation about calculating sample size for research studies.
How do I calculate the sample size for my study?
To calculate the sample size, you need to know the population size, margin of error, confidence level, and standard deviation.
What if I don't know the population size?
If the population size is unknown, you can use a conservative estimate or assume a large population, typically over 30.
Can you give me an example calculation?
Sure! If you want a 95% confidence level, a 5% margin of error, and a standard deviation of 0.5, you can use the formula: n = (Z^2 * p * (1-p)) / E^2.
What does Z represent in that formula?
Z represents the Z-score, which corresponds to your desired confidence level. For 95%, Z is approximately 1.96.
