What is a chi square test?
The Chi-square test is a statistical test that is usually used to test how well a data set fits some hypothesised distribution.
What conclusion is appropriate if a chi-square test produces a chi-square statistic near zero?
A chi-square statistic which is near zero suggests that the observations are exceptionally consistent with the hypothesis.
Chi-square test properties and importance?
square
What is the underlying principle of a chi square test?
The underlying principle is that the square of an independent Normal variable has a chi-square distribution with one degree of freedom (df). A second principle is that the sum of k independent chi-squares variables is a chi-squared variable with k df.

What are the key differences between a t-test and a chi-square test, and how do these differences impact their respective applications in statistical analysis?
A t-test is used to compare means between two groups, while a chi-square test is used to determine if there is a relationship between two categorical variables. The key difference is in the type of data being analyzed - t-tests are for continuous data, while chi-square tests are for categorical data. This impacts their applications as t-tests are used for comparing means, such as in experiments with control and experimental groups, while chi-square tests are used for analyzing relationships, such as in surveys or contingency tables.

What is the purpose of Chi Square Analysis?
Chi-square is mainly used for a goodness of fit test. This is a test designed to assess how well a set of observations agree with what might be expected from some hypothesised distribution.
Chi-square test properties and importance?

Why use chi-square?
the Chi Square distribution is a mathematical distribution that is used directly or indirectly in many tests of significance. The most common use of the chi square distribution is to test differences among proportions
