## What test do you use for matched pairs?

The paired t-test is a method used to test whether the mean difference between pairs of measurements is zero or not.

**How do you find the T value for a paired t-test?**

Paired Samples T Test By hand

- Example question: Calculate a paired t test by hand for the following data:
- Step 1: Subtract each Y score from each X score.
- Step 2: Add up all of the values from Step 1.
- Step 3: Square the differences from Step 1.
- Step 4: Add up all of the squared differences from Step 3.

### What is the difference between a matched pairs t-test and a 2 sample t test?

Two-sample t-test is used when the data of two samples are statistically independent, while the paired t-test is used when data is in the form of matched pairs.

### What is a matched pair in statistics?

Matched samples (also called matched pairs, paired samples or dependent samples) are paired up so that the participants share every characteristic except for the one under investigation. A “participant” is a member of the sample, and can be a person, object or thing.

**How do you do a matched pairs t-test in Excel?**

Step-by-Step Instructions for Running the Paired t-Test in Excel

- In Excel, click Data Analysis on the Data tab.
- From the Data Analysis popup, choose t-Test: Paired Two Sample for Means.
- Under Input, select the ranges for both Variable 1 and Variable 2.
- In Hypothesized Mean Difference, you’ll typically enter zero.

**What is a paired t test?**

Identify a sample statistic. Use the mean difference between sample data pairs (d) to estimate the mean difference between population data pairs (μ d ).

**What exactly is a “matched pair”?**

A “matched pair” is a set of two microphones that sound the same. Our pairs are hand-matched for both sensitivity (0.5dB @ 1kHz) and frequency response (1.5dB, 50Hz-15kHz). Those specs are just a technical way to express that the two mics sound essentially identical.
