To test how well observations agree with some expected distribution. The latter is often non-parametric so that tests based on the Gaussian (Normal) distribution are not appropriate.

The Chi-squared statistic can be used to test for association.
The Chi-square test is a statistical test that is usually used to test how well a data set fits some hypothesised distribution.
Yes, the chi-square test can be used to test how well a binomial fits, provided the observations are independent of one another and all from the same (or identical) binomial distribution.
There are many chi-squared tests. You may mean the chi-square goodness-of-fit test or chi-square test for independence. Here is what they are used for.A test of goodness of fit establishes if an observed frequency differs from a theoretical distribution.A test of independence looks at whether paired observations on two variables, expressed in a contingency table, are independent of each.
t test is used when- a) variables are studied b)the size of sample is a small one.(n<30) chi square test is studied when a) attributes are studied
A Chi-square table is used in a Chi-square test in statistics. A Chi-square test is used to compare observed data with the expected hypothetical data.
The Chi-squared statistic can be used to test for association.
The Chi-square test is a statistical test that is usually used to test how well a data set fits some hypothesised distribution.
Chi-Square Goodness-of-fit Test is used when you want to test if the sample observed follows an assumed theoretical distribution.
The chi-square test is pronounced "keye-skwair" test.
A t-test is used when comparing means of two groups, while a chi-square test is used for comparing frequencies or proportions of categorical data. Use a t-test when comparing numerical data and a chi-square test when comparing categorical data.
A t-test should be used to compare the means of two groups, while a chi-square test is used to compare frequencies or proportions between groups.

A chi-square test is used when analyzing categorical data, such as comparing proportions or frequencies between groups. On the other hand, a t-test is used when comparing means between two groups. So, use a chi-square test when dealing with categorical data and a t-test when comparing means.
