## Predict a Future/Unknown Value

Added Mar 22, 2014 by LathropHeartland in Statistics & Data Analysis

Evaluate a regression model (function) for any value x. You can input a single value, or a list values separated by commas.

## Normal Curve Percentiles

Added Mar 19, 2014 in Statistics & Data Analysis

calculates the percentiles for a normal distribution

## Verify the Equality of 3 or More Variances/St

Added Mar 18, 2014 by LathropHeartland in Statistics & Data Analysis

Outputs the maximum value and twice the smallest value. If first value is less than second value you can assume the populations have equal variances. This verifies one conditions for an ANOVA test.

## Verify the Conditions to Make Inferences Abou

Added Mar 18, 2014 by LathropHeartland in Statistics & Data Analysis

Verify the conditions to make inferences about 2 proportions.

## Calcuate the Critical Value for a QQ Plot

Added Mar 15, 2014 by LathropHeartland in Statistics & Data Analysis

Calculate the critical value for a QQ Plot. If the correlation coefficient (r) is less than this value, the population is non-normal. If r is greater than this value, the population is normal.

## Sample Size Needed to Estimate a Proportion

Added Mar 11, 2014 by LathropHeartland in Statistics & Data Analysis

Find the sample size needed to estimate a population proportion with a selected confidence level and margin of error.

## Test the Equality of Two Variances

Added Mar 11, 2014 by LathropHeartland in Statistics & Data Analysis

Performs an F-test to compare the variances of two samples from normal populations. The result is the p-value from this test.

## Test a Claim About 3 Averages

Added Mar 11, 2014 by LathropHeartland in Statistics & Data Analysis

Test a claim about three averages using a one-way ANOVA test (means), or the Kruskal-Wallis test (medians). For each test, the result is the p-value from conducting the test.
