Summary Statistics | Dundee Scientific | Given raw data for two populations, computes confidence intervals for each mean and the difference of means. more |
CI for one mean | Russ Lenth's Java applets for power and sample size | For a confidence interval for the mean, computes either required sample size to achieve specified margin of error or margin of error from specified sample size, has finite population options. more |
Sample size required for estimating a mean or total | Stattucino (Berrie) | Sample size calculator for a confidence interval for a mean, has finite population option. more |
One sample CI for the mean with known population standard deviation | Dept of Statistics, Texas A&M University | For a confidence interval for a mean using the normal, computes sample size for a specified margin of error or vise versa. more |
One sample CI for the mean with unknown population standard deviation | Dept of Statistics, Texas A&M University | For a confidence interval for a mean using the t, computes sample size for a specified margin of error or vise versa. more |
CI for one proportion | Russ Lenth's Java applets for power and sample size | For a confidence interval for the proportion, computes either required sample size to achieve specified margin of error or margin of error from specified sample size, has finite population options. more |
Sample Size Calculator | Raosoft, Inc. | Computes sample size for a confidence interval for a proportion based on a possibly finite population, includes explanations for each quantity entered, also gives margin of error for specified sample sizes or confidence levels. more |
Sample size required for estimating a proportion with absolute margin of error | Stattucino (Berrie) | Sample size calculator for a confidence interval for a proportion using an absolute margin of error, has finite population option. more |
