bullet1 Type of analysis


Sample size calculator offers you two main dimensions of analysis, each with 2 values:

  • means versus proportions
  • a single characteristic versus the difference between two characteristics

This amounts to four different kinds of analysis used in research:

  • Estimating a single mean
  • Concluding there is a difference between two means (or not)
  • Estimating a single proportion
  • Concluding there is a difference between two proportions (or not)

The example found below this page describes a real world example of the type of research you selected, to help you relating to your real world.
