Devised especially for business-to-business research, in which there are limited numbers of companies in the universe, our Sample Size Calculator will tell you how many companies you need to interview for a valid sample.
Using the Sample Size Calculator
- Select your ‘population size’ (i.e. your estimate of the total number of companies in the market).
- The ‘sample size’ box will automatically show the number of companies you need to interview.
The ‘sample size’ is the number of companies you need to survey to achieve a response that is accurate to within 5% (and to 95% confidence).
