Two Sample t-test: Definition, Formula, and Example
Suppose we want to know whether or not the mean weight between two different species of turtles is equal. Since there are thousands of turtles in each population, it would be too time-consuming and c…
10: Hypothesis Testing with Two Samples
This chapter deals with the following hypothesis tests: Independent groups (samples are independent) Test of two population means. Test of two population proportions. …
Two Sample t-test Calculator
A two sample t-test is used to test whether or not the means of two populations are equal. This type of test assumes that the two samples have equal variances. If this is not …
Two Samples Hypothesis Testing
Two-tailed paired samples hypothesis test: In engineering analysis, we often want to test whether some modification to a system causes a statistically significant change to the system …
How t-Tests Work: 1-sample, 2-sample, and Paired t …
T-tests are statistical hypothesis tests that analyze one or two sample means. When you analyze your data with any t-test, the procedure reduces your entire sample to a single value, the t-value. In this post, I describe how each type of t …
Hypothesis Testing for 2 Samples: Introduction
In this chapter we will address the test statistic for 2 proportions, 2 means (independent samples), and matched pairs (2 means from dependent samples). The formulas are listed in …
Two-Sample t-Test
The two-sample t -test (also known as the independent samples t -test) is a method used to test whether the unknown population means of two groups are equal or not. Is this the same as an A/B test? Yes, a two-sample t -test is used …
