🧠 Paired Samples T-Test in Excel | How to Interpret P-Value & Calculate 95% Confidence Interval
Welcome to the guide on performing a *Paired Samples t-test* (also known as a *Related Samples* or **Repeated Measures t-test**) using the **Excel Data Analysis ToolPak**.
This video shows how to perform a *paired t test* in *Excel* to test for a difference between two sample means. We examine the costs of medical procedures from two regional hospitals, walking through the *statistical analysis* step-by-step. Learn about *hypothesis testing* and how to interpret the results for your own *data analysis* projects.
This video walks you through the entire statistical analysis process, from data setup to result interpretation:
1. Setting up the hypothesis (mean difference is zero).
2. Running the paired test using the Data Analysis ToolPak.
3. Interpreting the output: T-statistic, critical value, and *P-value* for statistical significance.
4. Calculating the *95% Confidence Interval* for the true mean difference.
Master this fundamental test for research, medical studies, and other paired data comparisons.

Topic Deep Dive:
This statistical analysis tutorial focuses on a core procedure for testing for a mean difference in two related or dependent samples. Whether you refer to it as a paired samples t-test or a repeated measures design, this Excel method is a robust way to determine *statistical significance* and calculate the margin of error using the critical t-value.
