Microsoft Office has the most useful selection of tools that help and facilitate the work of many professionals today. And without a doubt, Microsoft Excel is one of the tools that easily stands out among the others because of the great handling and utility that it can be given in different areas.
Without a doubt, what makes Excel so special is the myriad of calculations, formulas, and functions that can be applied through simple methods. Thanks to its extensive spreadsheet, any amount of data entered can be managed in a data table, graphs, among many other options.
And as is to be expected, one of the fields that Excel can easily address to operate different formulas and data is in statistical operations. Being the Excel functions INV.T and INV.T.2C, one of the functions that any operator in this program must know to increase their mastery of the statistical functions of Excel.
What are the Excel functions INV.T and INV.T.2C?
The Microsoft Excel program has a wide selection of functions that makes mastering each and everyone a task for few users. However, a short review of each one is enough to know them and understand their usefulness, and when to use them.
On this occasion, of course, it addresses two of the statistical functions of Excel that may be needed at any time. As it is usually one of the least used, they make anyone see the need to need support for Excel.
The first is the statistical function INV.T, whose application returns the inverse of the left-tailed Student distribution. While the second statistical function INV.T.2C, when applied, returns the inverse two-tailed Student’s t distribution, that is, as a function of the probability and the degrees of freedom.
Remember that Student’s, also known as the distribution in both probability and statistics, is property distribution. This arises from the problem in estimating the mean of a normally distributed population when the sample size is small.
How do you use the Excel functions INV.T and INV.T.2C?
As expected, the use of the Excel functions INV.T and INV.T.2C is limited to those statistical problems where Student’s t is applied. And it should be noted that, as Excel functions, they have some arguments to consider when applying.
Syntax of the INV.Y and INV.T.2C functions
- Probability is a mandatory argument, it would be associated with Student’s distribution.
- Degrees_of_freedom is a mandatory argument, it indicates the number of degrees of freedom that characterizes the total distribution.
Application of the Excel functions INV.T and INV.T.2C
When it is required to use the INV.T or INV.T.2C functions, the procedure to apply them in the spreadsheets is the same. Obviously, its result will not be the same because both functions contain different formulas depending on their final application.
You start by selecting the cell where you want to see the result. Click on the insert function fx icon that will be located in the upper toolbar, or you can right-click on the selected cell to choose the option to insert function in the menu; remember that one of the benefits of Excel is its keyboard shortcuts for speed.
The next step is to select the group of Statistics functions in the displayed list that will allow you to click on the TINV or TINV.2C function as required by the statistical operation to be solved. This is how you proceed to enter the corresponding arguments separated by their respective commas, to finish by pressing Enter.
The result should be displayed successfully in the cell that has been selected to see the result from the initial step. So we hope this article has worked for you to use these very useful Excel functions.
How to Create a Table in Microsoft Excel
How to create a table in Microsoft Excel is very easy, you know, because basically, Excel consists of tables and a number processor.
The use of internal tables in this number processing software has become one of the things that are definitely needed, guys. Especially if you play with a lot of data in it.
However, until now there may still be many who do not know how to make it. Therefore, we will provide a complete tutorial for you.

How to calculate weighted average or weighted average in Excel
Simply having an Excel spreadsheet program installed on any of our devices, be it a desktop or a laptop, is an advantage for us, as long as we know how best to use it. Because in it we can perform an infinite number of operations, among which we can mention the calculation of the weighted average.
Excel is a very versatile tool that helps us perform many tasks and has an infinite number of functions to offer. Among them are: creating many types of charts, issuing invoices, keeping records and organizing various data, easy mathematical operations on the entered data, among we can mention data summation, among many applications for which we can assign it.
It should also be mentioned that this program allows us to work or share files with several people online and the fact is that sometimes teamwork is better than individual work, therefore it is the convenience that the program gives us, It’s very important.
Now, in this article, we will show you how to use Excel’s SUMPRODUCT and SUM functions individually, and how to combine both to calculate some problems.
The weighted average is an average that takes into account the importance or weight of each value. A good example would be the calculation of a student’s final grade based on his or her performance on various tasks and tests.
this is usually an individual assignment. They do not count as much for the final grade as for the final exam, as quizzes, tests and final exams will have different weights.
this weighted average is computed as the sum of all values multiplied by their weights divided by the sum of all weights.
For its part, a weighted average can be associated with a measure type that is able to calculate a weight with different values that can be calculated.
Example SUMPRODUCT and SUM
For our example, let’s take a look at the test results and student tests. There are six quizzes with 5% of the total mark each, two exams of 20% of the total mark and the final exam with 30% of the total mark.
The student’s final grade will be a weighted average and we will use the SUMPRODUCT and SUM functions to calculate this. As you can see in the table below, we have already assigned relative weights to each test and exam in column D.
Step one: calculate the SUMPRODUCT
First, let’s see how the SUM PRODUCT function works. Start by selecting the cell where you want the result to appear (in our example, this is cell D13).
Next, go to the “Formulas” menu, select the “Math and Trig” drop-down menu, scroll down and click on the “SUMPRODUCT” function.
- The “Function Arguments” window appears.
- In the “Array1” field, select the student results.
- Here we select all cells with actual results in column C.
- Then use the “Array2” field to select the weight of the tests and exams.
- For us, they are in column D.
- Click “OK” when finished.
- The SUMPRODUCT function will multiply each result by the corresponding weight.
- Then it will return the sum of all these products.
Step two: calculate the SUM
- Now let’s see how the SUM function works.
- Select the cell where you want the results to appear (in our example, this is cell D14).
- Then go to the “formulas” menu.
- Select the “Math and Trigonometry” drop-down menu.
- Scroll down and click on the “SUM” function.
- This “ function arguments “.
- Select all scales in the “number 1” field.
- Click “accept”.
- The SUM function will add all the values together
Step three: Combine SUMPRODUCT and SUM
But now we can combine both functions to determine the student’s final grade on the basis of his results and the weight of each result.
- Select the cell where the weighted average should go (for us, this is cell D15).
- Then type the following formula in the function bar.
= PRODUCT SUM (C3: C11, D3: D11) / SUM (D3: D11)
- After typing the formula, press “enter” to see the weighted average.
