Paired Sample t-Test: Definition, Uses and Example Paired samples occur when the observations in one sample are linked to observations in the other sample The most common example is before-and-after measurements on the same subjects, but it can also involve matched subjects or pairs
Paired T Test: Definition When to Use It - Statistics by Jim Paired t tests are also known as a paired sample t-test or a dependent samples t test These names reflect the fact that the two samples are paired or dependent because they contain the same subjects
8. 3 - Paired Means - Statistics Online In Lesson 1 we learned about independent samples and paired samples When we have two independent samples, the observations in the two groups are unrelated to one another and are not matched in any meaningful way
7: Paired Samples - San José State University Paired samples (also called dependent samples) are samples in which natural or matched couplings occur This generates a data set in which each data point in one sample is uniquely paired to a data point in the second sample
Matched or Paired Samples | Introduction to Statistics Two measurements (samples) are drawn from the same pair of individuals or objects Differences are calculated from the matched or paired samples The differences form the sample that is used for the hypothesis test
10. 4 Matched or Paired Samples – Statistics Study Guide If the choice of a sample member in one group automatically determines who's going to be selected from the second group, then the samples are dependent In these samples, there's a distinct connection between members of the two samples
8. 1: Paired Samples - Statistics LibreTexts We will learn how to construct interval estimates and test hypotheses using paired data Consider the two scenarios below The planet’s average surface temperature has risen about 2 degrees Fahrenheit (1 degree Celsius) since the late 19th century
Paired Sample T-Test - Statistics Solutions The paired sample t -test, sometimes called the dependent sample t -test, is a statistical procedure Specifically, it determines whether the mean difference between two sets of observations is zero
