The calculator above will graph and output a simple linear regression model for you, along with testing the relationship and the model equation. Keep in mind that Y is your dependent variable: the one …

Calculate P from t, z, r, F or chi-square, or vice-versa. View Binomial, Poisson or Gaussian distribution. Correct a P value for multiple comparisons and Bayes.

You can use statistical software such as Prism to calculate simple linear regression coefficients and graph the regression line it produces. For a quick simple linear regression analysis, try our free …

Free web calculator provided by GraphPad Software. Calculates the P value from z, t, r, F, or chi-square.

Enter data for multiple regression, choosing a model for multiple regression, setting reference levels for multiple regression, interpolation (prediction) with ...

This calculator uses a two-sample t test, which compares two datasets to see if their means are statistically different. That is different from a one sample t test, which compares the mean of your …

Post test following two-way (or higher) ANOVA. Confidence interval of a sum, difference, quotient or product of two means. Confidence interval of a standard deviation. Linear regression. Analyze, graph …

This calculator is built for simple linear regression, where only one predictor variable (X) and one response (Y) are used. https://www.graphpad.com/quickcalcs/linear1/

If you collected replicate Y values at every value of X, there are two ways to calculate linear regression. You can treat each replicate as a separate point, or you can average the replicate Y values, to …

Prism offers two forms of simple regression: simple linear regression and simple logistic regression. Although these analyses are related, we discuss them separately.
