1Cohen (1988) Statistical power analysis for the behavioral sciences (2nd ed.). Hillsdale,NJ: Lawrence Erlbaum is a classical reference. You might also consider the pwr package if you are familiar with R. – utobi Jan 07 '19 at 08:09

If you have access to any good statistical package (such as R or SAS) there are prepackaged tools for doing this (the pwr package in R and PROC POWER in SAS). There are probably similar tools in other statistical packages.
Otherwise, you can look into the book by Cohen that @Utobi referred to in a comment.
