    What Is Chi-Square Test?

    Chi-square is a statistical test that is conducted to compare the data that is observed and the data that is expected based on the hypothesis that is given. Mendel’s law would be used to learn in detail about Chi-square testing. For instance, if one expects 20 offspring of which 10 would be male, the actual observed number would be 8. You can establish the facts of what was observed and what was expected from you earlier. This test is also conducted to compute the expected deviation. The Chi-square test that is conducted for the null hypothesis will help you to find the difference between the observed results as well as the expected results. 

    This is the common test that is found in statistics and is used to carry out non-parametric tests. This kind of test is represented by x2, which is actually a Greek letter that will explain the extent of observations as well as the discrepancies in the theory. We have experienced and professional tutors who would assist you in writing the assignment flawlessly. The assignment that is composed of our experts would be technically accurate and comprehensive. Students who are struggling with their academic work and personal things can hand over the responsibility of writing the assignment to us. We do it for you with high dedication and commitment before the given deadline. Our Chi-square Testing project Help experts write on any topic related to chi-square testing irrespective of its complexity levels. 

    This is the test that is conducted to check the difference in the observed frequencies and the expected frequencies in a particular category. This lets you combine the responses of two or more specific groups belonging to different categories. This type of test is carried out only with real numbers, but not using any proportions or percentages. Our adept professionals will help you to understand the concepts related to chi-square testing. They are available round the clock to offer you valuable guidance. This type of test can open only a particular dataset over a period of time. This chi-square testing is done in the summary information investigation. This type of testing is best used for minimum measurements. This comprises a degree of freedom and the distribution is done based on the random variables. The Chi-square distribution is widely used in hypothesis testing and in solving statistical dependent probability issues. 

    There are three key variances that are used in this type of testing. These include – goodness to fit, homogeneity, and contingency. The standard normal deviation and degree of freedom would be equaled as well as summed in the whole distribution process. There is one constant that you can observe in this test, which is represented by K. This is also called the “degree of freedom”.

    The chi-square test is better explained with an example of the coin toss. For instance, if you toss a coin, there are chances of you getting head and tail are 50-50. If you flip the same coin 100 times, then you may get heads 50 times and tails 50 times. The actual result may be different from what you are expecting. In actual scenarios, you may get 50 times head and 40 times tails. This kind of discrepancy can be easily measured with the help of the chi-square test. 


    Applications Of Chi-Square Test

    There is a wide range of applications that use the Chi-square test. We would like to list down the 3 important ones:

    1. Goodness to fit
    2. Independent of attributes ad
    3. Test of homogeneity 


    Chi-Square Test - Goodness To Fit

    This is the test that is carried out with a sample that represents the population. This type of test will be verifying the sample data, which is uniform with the hypothesis distribution of the population. A few of the conditions that one should meet include:

    • A sample random sampling method
    • A variable that is defined categorically
    • Sample observations will be equal to or more than 5


    Chi-Square Test For Independence

    This is the second type of chi-square test. In this type of test, there are two variables along the independence between these terms is validated. This can also be explained in the other way. If you have two variables, the chi-square test for independence will help you to find the distribution of these two independent variables with each other.

    Many professors will be assigning the students to write an academic paper on this type of test. You can seek the Chi-square Testing homework Help of our professionals to complete it with high accuracy and on time. If the chi-square test statistic is too minute, then there exists a relationship between the two variables and if the variation is too big, then no relationship exists between the two variables. 

    Validation Of Chi-Square Test

    The Chi-square test can be used in statistics only if the following conditions are fulfilled:

    • The number of frequencies in total should be more than 50.
    • Sample observations should not depend on each other. There is no item that has to be included twice in the given sample.
    • Constraints that are on the cell frequencies should be linear.
    • There is no theoretical frequency that should be too small. If the expected frequency is less than the value of x2, then it gets overestimated. This would result in rejecting the null hypothesis. Every theoretical frequency should be more than 10 and in a few cases, it should be less than 5. If the theoretical frequency is less than 5, you cannot use x2 for testing.

    Frequently Asked Questions

    Chi-Square tests are appropriate for nominal-level measurements in which the samples are counts of items arranged in categories. For example college students can be categorized according to whether they are freshmen, sophomores, juniors’ or seniors. If a sample of college students is taken and the number of students in each of the four categories is recorded, then those data are nominal-level measurements that can be analyzed with a chi-square test.

    There are a wide range of applications that use Chi-square test. We would like to list down the 3 important ones:

    • Goodness to fit

    • Independent of attributes ad

    • Test of homogeneity 


    The chi-squared distribution has a variety of applications in statistics, including:

    • Estimation of a population standard deviation of a normal distribution from a sample standard deviation using a confidence interval.

    • Two classification criteria for qualitative variables are independent.

    • Categorical variables and their relationships (contingency tables).

    • When the underlying distribution is normal, sample variance analysis is used.

    • Differences between expected and observed frequencies are tested using deviations (one-way tables).

    • The chi-square test is a statistical method for determining whether or not something is true (a goodness of fit test).


    This test determines whether or not a single sample is representative of the entire population. The goodness of fit test is used to see if the sample data matches a population distribution that has been hypothesised. For the goodness of fit test to be valid, several requirements must be met.

    • The variable must be categorically specified 

    • The number of sample observations must be equal to or more than 5 

    • A simple random sampling approach is utilised


    A p-value is determined via a chi square test. The p-value indicates whether or not your test results are significant. You'll need two pieces of information to run a chi square test and determine the p-value:

    • The concept of degrees of freedom. It's simply the number of categories divided by one.

    • The alpha value. You or the researcher decide on this. The most common alpha level is 0.05 (5%), but other levels such as 0.01 or 0.10 are also possible.
