Paired t-test: How to use paired t-test (dependent sample t-test) to compare means of 2 matched, paired, or dependent groups.

Either way, We Thank You! • • ▶︎ The paired t-test is used to compare the means of 2 matched, paired, or dependent groups. It essentially becomes the univariate (one sample) t-test, by taking the difference in observations in the 2 groups and then conducting a test on the mean difference. • ▶︎ The paired t-test is also known as paired two-sample t-test, paired-sample t-test or dependent sample t-test. • ▶︎ We also cover building a confidence interval for the mean difference, as well as how this can be used to test a hypothesis. • ▶︎ While we do show the calculations in the video, the video focuses on the concepts underlying the test. • ▶︎ Common applications of the paired sample t-test include case-control studies or repeated-measures designs. • ▶︎▶︎Make sure to check out our R video tutorial on how to conduct the paired t test here: https://goo.gl/cV4wkU • ► ► Watch More: • ► Intro to Statistics Course: https://bit.ly/2SQOxDH • ►Data Science with R https://bit.ly/1A1Pixc • ►Getting Started with R (Series 1): https://bit.ly/2PkTneg • ►Graphs and Descriptive Statistics in R (Series 2): https://bit.ly/2PkTneg • ►Probability distributions in R (Series 3): https://bit.ly/2AT3wpI • ►Bivariate analysis in R (Series 4): https://bit.ly/2SXvcRi • ►Linear Regression in R (Series 5): https://bit.ly/1iytAtm • ►ANOVA Concept and with R https://bit.ly/2zBwjgL • ►Hypothesis Testing: https://bit.ly/2Ff3J9e • ►Linear Regression Concept and with R Lectures https://bit.ly/2z8fXg1 • Follow MarinStatsLectures • Subscribe: https://goo.gl/4vDQzT • website: https://statslectures.com • Facebook: https://goo.gl/qYQavS • Twitter: https://goo.gl/393AQG • Instagram: https://goo.gl/fdPiDn • Our Team: • Content Creator: Mike Marin (B.Sc., MSc.)
