1. What Is the CHITEST Function in Excel?<\/strong><\/h2>\nThe Microsoft Excel CHITEST function returns a value from a Chi Square distribution. The CHITEST function is an integrated function in Excel and is classified as a statistical function Can be used as a worksheet function (WS) in Excel. As a worksheet function, the CHITEST function can be entered as part of the formula in a worksheet cell. By using the CHITEST function in Excel, the probability of observing a particular data record is determined by whether the null hypothesis is true or not.<\/p>\n
It helps you understand whether the distribution of data expects a predicted distribution that is often used in hypothesis tests. The CHITEST function helps you determine the likelihood that a cube will achieve this result when it is actually fair. The function returns test statistics for the chi-square distribution. This is a measure of the expected amount of observed data Values that are too close to the observed and expected data indicate an exact matching, whereas those that have a significant difference do not.<\/p>\n
2. When to Use CHITEST in Excel?<\/strong><\/h2>\nOnce you know what CHITEST is doing, let’s talk about when it can be used. This is primarily used for statistical hypothesis tests, especially categorical data These are some cases where CHITEST can be of great use.<\/p>\n
\n- Note Test:<\/strong> Determine if the sample matches the population<\/li>\n
- Test Independence:<\/strong> Ensures that two categorical variables exist independently of each other.<\/li>\n
- Comparison of distributions:<\/strong>A comparison of the distribution. The expected distribution is reflected in observation data.<\/li>\n<\/ul>\n
Practically, if you want to address categorical data and test assumptions via distribution, CHITEST is the point of contact Imagine.<\/p>\n
3. Syntax of in Excel.<\/strong><\/h2>\nIt’s important to follow the Chitest syntax correctly, even though it may seem simple.<\/p>\n
CHITEST(actual_range, expected_range)<\/strong><\/p>\nactual_range:<\/strong> This is the area of \u200b\u200bobservation data representing the collected count or frequency.<\/p>\nexpected_range:<\/strong> This is the area of \u200b\u200bpredicted data determined based on a hypothesis or theoretical model.<\/p>\nBoth areas must have the same measure If the real data comes from some 3×3 network, then it should be available as well. It is important to make sure this is not possible.<\/p>\n
4. How to use CHITEST function in excel? Example-1<\/strong><\/h2>\nStep 1:<\/strong> Here using two tables to determine the actual and expected frequency of liking Chips in Children and adults in different districts follow the sample data set as an example below.<\/p>\nEntering the data here.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-1.jpg\")
<\/p>\n
Step 2:<\/strong> Now, add other Rows in D1:D8 to calculate the row sum and add other columns in A8:C8 to calculate the Column sum there.<\/p>\nThe columns and rows have been added underneath.<\/p>\n

![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-7.jpg\")
<\/p>\n
Step 8:<\/strong> Now, use them same formula as shown in B8 or drag them cursor from B8:C8.<\/p>\nHere is them C3:C7 column sum.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-8.jpg\")
<\/p>\n
Step 9:<\/strong> You can use the formula for D8: =SUM(D3:D7)<\/strong> or =SUM(B8:C8) <\/strong>in the D8 cell.<\/p>\n=SUM(D3:D7) formula is using here.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-9.jpg\")
<\/p>\n
Step 10:<\/strong> Press the input key. Both of these formulas yield the same outcome.<\/p>\nHere is them output.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-10.jpg\")
<\/p>\n
Step 11:<\/strong> To determine the frequencies of each individual cell, you can use this formula:\u00a0 Row Sum*Column Sum\/Total<\/strong><\/p>\nIn the B13 cell, input this formula: =D3*B8\/D8<\/strong> as appears below.<\/p>\n![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-11.jpg\")
<\/p>\n
Step 12:<\/strong> Now, press enter and the Observed Frequencies of liking chips of cell B13 result will come out.<\/p>\nHere is the result.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-12.jpg\")
<\/p>\n
Step 13:<\/strong> Here you can use the the same formula from Step 11 but changing with them cell number from B13:B17. Here are all them formulas:<\/p>\n=D4*B8\/D8<\/strong><\/p>\n=D5*B8\/D8<\/strong><\/p>\n=D6*B8\/D8<\/strong><\/p>\n=D7*B8\/D8<\/strong><\/p>\nHere are the results of B column.<\/p>\n

Step 15:<\/strong> Tap on enter button.<\/p>\nHere is the output.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-15.jpg\")
<\/p>\n
Step 16:<\/strong> You can use the same formula from Step 14 but changing with them cell number from C13:C17. Here are all them formulas:<\/p>\n=D4*C8\/D8<\/strong><\/p>\n=D5*C8\/D8<\/strong><\/p>\n=D6*C8\/D8<\/strong><\/p>\n=D7*C8\/D8<\/strong><\/p>\nHere are the results of B column.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-16.jpg\")
<\/p>\n
Step 17:<\/strong> The difference between the expected and actual ranges of data sets is not significant when the CHIEST function produces a zero value. Figures from screenshots reveal that the frequencies of Children and the Adults observed have been adjusted for different states. Now, add other columns to enter the Significance Level and to get the result of CHIEST function.<\/p>\nAdding the columns here.<\/p>\n

![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-18.jpg\")
<\/p>\n
Step 19:<\/strong> This value is very close and is usually displayed as a p-value in the CHIEST test when the observed data is very unlikely under the null hypothesis. There are probably very large test statistics. This means there is a big difference between the observed and expected values. The importance of these outcomes makes it virtually impossible to achieve them by chance (under the null hypothesis). However, they are significant. There is no difference between observed and expected data<\/p>\nHere is the CHIEST function output.<\/p>\n

5. How to use CHITEST function in excel? Example-2<\/strong><\/h2>\nStep 1:<\/strong> Take some information as Actual range and Expected range. First make a data table as shown below.<\/p>\nEntering the data here.<\/p>\n
![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-20.jpg\")
<\/p>\n
Step 2:<\/strong> Now, add the column in G1 and G2 for getting the result.<\/p>\nThe column has been added.![\"CHITEST](\"https:\/\/www.bizinfograph.com\/resource\/wp-content\/uploads\/2025\/05\/CHITEST-Function-21.jpg\")
<\/p>\n
Step 3:<\/strong> Use them CHIEST function formula in cell G2. For this, the formula is: =CHITEST(A2:B4,D2:E4)<\/strong><\/p>\nPlacing the formula here.<\/p>\n

<\/p>\n
Step 4:<\/strong> After applying the formula press enter and you will get the result. If the field value of the expected area dataset is zero, then CHIEST function will give the output as#DIV\/0! Error. You can see in the screenshots that #DIV\/0! is shown below whereas computing CHITEST function.<\/p>\nHere is the output of CHIEST function.<\/p>\n
