The t test compares one variable (perhaps blood pressure) between two groups. Use correlation and regression to see how two variables (perhaps blood pressure and heart rate) vary together. Use correlation and regression to see how two variables (perhaps blood pressure and heart rate) vary together. A one sample t test compares the mean with a hypothetical value. In most cases, the hypothetical value comes from theory. For example, if you express your data as 'percent of control', you can test whether the average differs significantly from 100. One sample t test. A one sample t test compares the mean with a hypothetical value. In most cases, the hypothetical value comes from theory. For example, if you express your data as 'percent of control', you can test whether the average differs significantly from 100. The hypothetical value can also come from previous data.

Here you need to tell GraphPad which test to perform. Select the ‘ t-tests (and nonparametric tests) ’ analysis and make sure the two datasets are ticked on the right window. Click the ‘ OK ’ button. The next window will ask you to specify whether the t-test is an unpaired (independent) or paired (dependent) test. In this video tutorial, I will explain how to perform an unpaired (independent) Student T-test in GraphPad Prism. I will also show you how to interpret the results. THE ONLINE GUIDE http

## To perform an unpaired (independent) T-test in GraphPad Prism you will need to enter two groups of data into separate columns. Upon opening GraphPad Prism,

THE ONLINE GUIDE http This video explains how to use Graphpad.com to conduct a t-test including how to interpret p-values in relation to the null hypothesis. Descriptive statistics, detect outlier, t test, CI of mean / difference / ratio / SD, multiple comparisons tests, linear regression. Statistical distributions and interpreting P values Calculate P from t, z, r, F or chi-square, or vice-versa.

### The calculator below implements most known statistical test, namely, Independent Samples t-test or Two samples t-test. t-test also known as Student's t-test, after William Sealy Gosset. "Student" was his pen name. The test deals with null hypothesis such that the means of two populations are equal.

7 Jan 2019 GraphPad Prism is a software application for scientific graphing, curve fitting and statistical testing. It has been popular among scientists,

### Online outlier calculator. Don't use commas as decimal marks; commas with digits adjacent on both sides are interpreted as Dixon's test for a single outlier

You'll master the program in just a few minutes – really. Clear analysis choices with explanations. You don't have to know the name of the test you need. InStat  Several factors influence the power of the t-test to detect significant differences.

For reasonably large sample sizes, a t-test will provide virtually the same answer and is currently We note that an online tool has been created by Shai Shaham (Shaham, 2007) that allows users to http://www.graphpad.com/quickcalcs/. This calculator will tell you the (two-tailed) effect size for a Student t-test (i.e., Cohen's d), given the mean and standard deviation for two independent samples of  sample sizes for each sample;; specified significance level; and; whether test is one-tailed or two-tailed. Outputs include: difference in sample proportions
