Description

This statistics calculator computes test-statistics and p-values for standard hypothesis tests, as well as calculates confidence intervals. This app is a perfect addition to the many scientific and graphing calculators in the app store that do not possess this functionality. There are 26 solvers in this $0.99 (U.S. Store) app:

Statistics Input:

- 1-Sample Z-Test

- 2-Sample Z-Test

- 1-Proportion Z-Test

- 2-Proportion Z-Test (pooled and unpooled)

- 1-Sample T-Test

- 2-Sample T-Test (pooled and unpooled)

- 1-Sample Z-Interval

- 2-Sample Z-Interval

- 1-Proportion Z-Interval

- 2-Proportion Z-Interval (pooled and unpooled)

- 1-Sample T-Interval

- 2-Sample T-Interval (pooled and unpooled)

List Input:

- 1-Sample Z-Test

- 2-Sample Z-Test

- 1-Sample T-Test

- 2-Sample T-Test (pooled and unpooled)

- 1-Sample Z-Interval

- 2-Sample Z-Interval

- 1-Sample T-Interval

- 2-Sample T-Interval (pooled and unpooled)

To BendrixPilot: Even if you select one of the list input solvers, you will still need to add additional information depending on the test you are doing for example, a 1-Sample Z-Test will require you to input a population mean and standard deviation in addition to the list data you are including. Your list data is saved and will be used to calculate SAMPLE mean, SAMPLE standard deviation, and number of trials in the hypothesis test or confidence interval, but POPULATION mean and POPULATION standard deviation are still required to perform a valid 1-Sample Z-Test. Please contact me at statistics.calculator@gmail.com if you have any further questions.

To enter the data, simply type in the list values of your dataset, separated by commas. For example:

List 1: 1, 6, 23.5, 3, -2.5, 2, 11, 22.3, 2, 10.43

List 2: 11, 12.3, 1, -4.3, 5, 2, 9, 2.5, 4, 11, 20, 2

Negative and decimal numbers are fully supported.
