There is a sample size calculator which helps you decide how many interviews you will need to conduct. This is used in study design. We have also developed several statistical calculators which test the survey results for accuracy or significant differences. If you know which calculator you need for your analysis, you can jump directly to it using the links on the left. If you are not sure which one is most appropriate, you can use the Statistical Test Chooser to guide you in selecting the proper one. If you have questions or you feel a different test is more appropriate, please contact us and we would be happy to assist you. |
