## What Are T-Value and T-Distribution?

T-values is a test in statistics that is used in the hypothesis test to evaluate the sample data. When the t value becomes extreme then you have to understand that the sample data is not compatible with the null hypothesis so you have to reject the hypothesis. The t-score for the sample dataset extracts the relation between the sample and the null hypothesis which are as follows:

- The t-score becomes zero when the sample data meets the null hypothesis target accurately.
- The sample data becomes extremely different from the null hypothesis then the t-score becomes large.

**What Is T-Distribution?**

After calculating the t-value for the full population, you may try more times for random sample data of the same size as the population. Then, plotting the t-values in a graph will create the t-distribution. It is called sample distribution which is one type of Probability Distribution.

In statistics calculation, the t-score is used in many ways.

- The t-score helps to decide whether you will accept or reject the null hypotheses.
- You can calculate the probabilities from the T-score.
- Different formulas are used for a single sample, paired sample, and independent samples.

## What Are T-Score Formulas?

The t score or t-test is a hypothesis test that is used to compare sample datasets. It may be preferable for you to use the T score when you don’t have the standard deviation of the full dataset and the sample dataset is less than under thirty. The formula of the T score is as follows:

Here,

**x̄ **= Mean of the sample

**μ0** = Mean of the population

**s** = Standard deviation of the sample dataset

**n** = Sample size

**Formula of Paired Sample T-Test:**

If you want to compare 2 sample datasets using the generic formula then you have to use this formula:

Here,

**Mean 1** = **Average **of the first sample data

**Mean** **2** = **Average **of the first sample data

**S** **(Difference)** = **Standard Deviation** of the difference of paired data.

**N** = Sample size

**Formula of Two Samples Assuming Equal Variances:**

For the case of equal variances, use the formula shown below:

**Formula of Two Samples with Unequal Variances:**

**T-Distribution and Sample Size:**

The sample size has a large influence on the t distribution graph. The degree of freedom (DF) depends on the size of the dataset. When the DF increases, the t-distribution tails become thicker and the thicker tail means that the t-scores are far from zero despite being the null hypothesis correct.

## 4 Methods to Calculate T-Score in Excel

In this section, I will show you 4 quick and easy methods to calculate the T score in Excel on Windows operating system. You will find detailed explanations of methods and formulas here. I have used **Microsoft 365 version** here. But you can use any other versions as of your availability. If any methods don’t work in your version then leave us a comment.

### 1. Calculate T-Score Using Data Analysis ToolPak in Excel

Now, we are going to use Excel Data Analysis ToolPak to T-Test analysis of the dataset. The T-Test is of three types:

- Paired two samples for means
- Two samples assuming equal variances
- Two- samples using unequal variances

Now, we are going to do a t-Test: Paired Two Sample for Means. And you can use a similar way to do a t-test for the other two types. Here, we have a dataset containing the Students’ IDs and each student’s Math and Physics scores. Let’s walk through the steps to do a t-Test: Paired Two Sample for Means analysis.

📌 **Steps**:

- First, go to the
**Data**tab in the top ribbon. - Then, select the
**Data Analysis**

- When the
**Data Analysis**window appears, select the**t-Test: Paired Two Samples for Means** - Then, click on
**OK**.

In the** t-Test: Paired Two Sample for Means** pop-up box,

- Insert data in the
**Input**box, and provide the data ranges in the**Variable 1 Range**and**Variable 2 Range** - In the
**Output Range**box,**select**the data cell that you want your calculated data to store by dragging through the column or row. Or you can show the output in the new worksheet by selecting**New Worksheet Ply**and you can also see the output in the new workbook by selecting**New Workbook**. - Next, you have to check the
**Labels**if the input data range with the label. - Then, click on
**OK**.

As a result, you will get the following result of the t-Test: Paired Two Sample for Means.

### 2. Calculate T-Score Using T.TEST and T.INV.2T Functions in Excel

In Excel, there is a pre-defined function to calculate the T score from the P stat values. Follow the below steps to use Excel functions to calculate the T score.

**📌 Steps:**

- First, you have to calculate the P value of the paired sample datasets. Use the
**T.TEST function**to calculate the P score. Paste this formula into the cell G5 to get this:

`=T.TEST(C5:C12,D5:D12,2,1)`

**🔎 Formula Explanation:**

**▶ Syntax: =TTEST(array1,array2,tails,type)**

**Array1 = C5:C12**: The first data set**Array2 = D5:D12**: The Second data set**Tails = 2**: The number of distribution tails is defined. 1 for one-tailed distribution and 2 for two-tailed distribution**Type = 1**: 1 for Paired. 2 for Two-sample equal variance (homoscedastic), 3 for Two-sample unequal variance (heteroscedastic).

- Then, use the
**T.INV.2T function**to calculate the T score from the P value of the dataset. For this paste this formula into cell G6.

`=T.INV.2T(G5,7)`

**🔎 Formula Explanation:**

**▶ Syntax: =T.INV.2T(probability, deg_freedom)**

Where,

**Probability= G5:** The probability or P score that has been used.

**Deg_freedom= 7:** It is the value degree of freedom which is 1 minus of total count of sample data.

Thus, you have calculated the P score of a paired dataset using Excel Functions.

### 3. Use Generic Formula to Calculate T-Score

Also, you can use the generic formula to calculate the T score if you have all the required values in hand. The formula for the T score is as follows below. Through this formula, you will compare a sample dataset with the full population data.

To calculate the T score using this follow these steps.

**📌 Steps:**

- First, insert the values in the cells from
**C3 to C6**. - Then,
**paste**this into the cell**C8**to get the T score:

`=(C3-C4)/C5/SQRT(C6)`

- Thus, you have got the T score for the sample dataset compared with the full population.

### 4. Use Generic Formula of Paired Sample T-Test

If you want to compare 2 sample datasets using the generic formula then you have to use this formula:

To calculate the T score of paired sample datasets, follow the steps below.

**📌 Steps:**

- First, calculate the mean 1 and mean 2 using the
**AVERAGE function**. Paste this formula into cell H4 for mean 1.

`=AVERAGE(C5:C12)`

And, in cell H5 for a mean 2

`=AVERAGE(D5:D12)`

- Then, calculate the Standard deviation, using the
**STDEV.P function**. Paste this formula into cell H6

`=STDEV.P(E5:E12)`

- After that, calculate the total size of the sample dataset using the
**COUNT function****.**Paste this formula into cell H7

`=COUNT(E5:E12)`

- Finally, use this formula in cell H9 to get the T score.

`=(H4-H5)/(H6/SQRT(H7))`

Finally, you have got the T score of the sample datasets.
