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 …

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.

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. …

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 …

Linear regression is used to model the relationship between two variables and estimate the value of a response by using a line-of-best-fit. https://www.graphpad.com/quickcalcs/linear1/

Learn how to perform regression analysis when you have two groups, say treatment and control, and learn to test for differences between the two regression models

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

There are several types of two sample t tests and this calculator focuses on the three most common: unpaired, welch's, and paired t tests. Directions for using the calculator are listed …

At the bottom of the results page, the slope and intercept are reported again in the form of the equation that defines the best-fit line. You can copy this equation and paste onto a graph, or …

Prism can fit standard curves using nonlinear regression (curve fitting), linear regression, or a cubic spline (or LOWESS) curve. To find "unknown" concentrations using a standard curve, …
