Market Research Calculators

July 17, 2020 SPH Analytics

SPH Analytics has developed several calculators that are useful to market researchers and can be used to address common problems such as sample size calculation, sampling error calculation and statistical power calculation.

Sample Size Calculator

The SPH Sample Size calculators allow researchers to determine the sample size needed for a particular problem whether looking at averages or percentages, one sample or two.

Sampling Error Calculator

Once a study has been conducted, the DSS Sampling Error calculator indicates the sampling error for a particular confidence level. 

Statistical Power Calculator

Use the DSS Statistical Power calculator to determine the beta error or statistical power for a given sample or samples. Both one-tail and two-tail tests can be performed on averages and percentage values.
