Discover how to apply the Paired Sample t‑Test in chemical analysis! In this tutorial, we’ll explore how to compare two related sets of data — such as “before” and “after” measurements — to determine if there is a statistically significant difference. You’ll learn how to:
Understand when to use a paired sample t‑test
Calculate differences between paired observations
Compute the mean difference, standard deviation, and t‑value
Interpret results using p‑values and critical values at the 95%
confidence level
Decide whether to accept or reject the null hypothesis
This step‑by‑step guide is designed for chemistry students, educators, and researchers who want to strengthen their statistical analysis skills and confidently interpret laboratory results. By the end of this video, you’ll know how to use the paired sample t‑test to evaluate chemical data and explain your findings clearly.
