I am sorry we haven't compiled a complete manual to use our calculators.

To calculate the sample size using any of the calculators, you can input the desired power in the "Power" field and then remove the sample size in the "Sample size" field (leave it blank). Then the output will display the needed sample size according to the power you specified.
