You can use this free sample size calculator to determine the sample size of a given survey per the sample proportion, margin of error, and required confidence level
Power calculations are rarely done by hand. Instead, researchers normally refer to tables of critical values in much the same way that tables of critical values for t, F, and other statistics were once used to assess statistical significance. A far easie

When we were solving the problem of implementing a RPN calculator, we noted that it worked fine as long as the input that it got made sense. But if something went wrong, it caused our whole program to crash. Now that we know how to take some code that we have and make it monadic,...
