# What is the syntax for using the CD CHICADIST function in Excel?

Human beings are special because not only do we have the 5 senses but we are also capable of anticipating events before they occur.

Although it usually happens that on certain occasions we can fail our ability to predict both positive and negative things, failures, triumphs or dangers.

But it does not mean that we are gods when predicting, we just have a mathematical calculation that allows us to know what will happen, this calculation is called probability.

In probability, what we know from the Laplace rule is used, this rule consists of calculating the average of the cases by performing a division.

The cases that are favorable are represented in numbers in the numerator   and the average of the cases that are possible in the denominator.

Probability is used in various areas of calculation such as physics, social sciences, statistics, mathematics, accounting, finance, economics.

However, many use probability to determine the odds they have of winning or losing in numerous games.

Each of these distributions contains functions such as the Student’s t distribution that helps to calculate the tail distribution.

In probability there are several operations for you to make your calculations, including the distributions that are divided in several ways: discrete uniform distribution, binominal distribution, continuous uniform distribution, Student’s t distribution, Snedecor   distribution, exponential distribution, chi-square distribution.

The Gamma distribution contains values ​​for the calculation of alpha and beta , even in the chi-square distribution or also known as chicuad it has its functions.

## What is the chi-square or Chicuad distribution?

The chi-square or chicuad distribution is the one that allows you to calculate the observed distribution that you develop when executing the goodness of fit, with qualitative data as well as knowing what is the confidence interval that is taken into account in a deviation of the standard type.

This standard deviation also develops from the population when you calculate the normal distribution as a whole, with the standard deviation that you get when calculating the sample.

The chi-square distribution is also known as the Pearson distribution, which are represented by those degrees of freedom that arise from the random variable with the aforementioned calculations.

These parameters are made up of k ϵ N, each of these symbolizes the degrees of freedom that each of them is calculated in the random variable, the chicuad is known as X².

Previously these calculations were performed manually, now to save time and resources you can perform them in an automated way.

For this you have Microsoft Office that offers you endless tools with which you can perform your calculations, because it contains in its Excel calculation sheets formulas, calculations and functions, without complications that will facilitate your work.

The CHICUAD.DIST is used to perform statistical calculations in order to calculate the probability that comes from obtaining the result of the right tail, as well as its distribution and its square.

You can apply the syntax of this distribution in this way: DISTR.CHICUAD.CD (x. Degree-freedom), but below I will show you how to do it step by step.

### Step 1

In your Excel spreadsheet proceed to choose the cell where you want the result of the CHICUAD function to be calculated to be reflected.

### Step 2

Now for you to insert the function, look for the tab with the option Insert function, which you can see in your Excel toolbar or just press right click, already being in the cell choose Insert function that is available in the menu.

### Step 3

Next, look for the Statistics functions that you will observe and in the list that you will find you will see the option CHICUAD.CD DISTRICT and press click.

### Step 4

Then you can enter your data that you want to calculate, but each of them must be separated using commas so that it performs the function better.

### Step 5

To finish, you just have to press Enter and you will immediately know the precise data for the calculation of the function already performed.
