What is the difference of chi-square and t test?
They are applicable in different circumstances.
In a chi-square test the null hyopthesis is always?
Assumed that there is no relationship between variables.
WHAT IS THE Difference between A t test and chi square?
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
Is Chi-square a test of association?
The Chi-squared statistic can be used to test for association.
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 is the difference of chi-square and t test?
They are applicable in different circumstances.
In a chi-square test the null hyopthesis is always?
Assumed that there is no relationship between variables.
How does the difference between fe and fo influence the outcome of a chi-square test?
The larger the difference, the larger the value of chi-square and the greater the likelihood of rejecting the null hypothesis
How do pronounce chi-square test?
The chi-square test is pronounced "keye-skwair" test.

What is a Chi Square table used for?
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.
What are the differences between a two sample t-test and a chi-square test, and how do they each contribute to statistical analysis?
A two-sample t-test is used to compare the means of two independent groups, while a chi-square test is used to determine if there is a relationship between two categorical variables. The t-test helps determine if there is a significant difference in means, while the chi-square test helps determine if there is a significant association between variables. Both tests are important tools in statistical analysis for making inferences about populations based on sample data.
What is the difference between a paired t-test and a chi-square test, and when would you choose to use one over the other in statistical analysis?
A paired t-test is used to compare the means of two related groups, while a chi-square test is used to determine if there is a significant association between two categorical variables. You would choose a paired t-test when comparing means of related groups, such as before and after measurements. You would choose a chi-square test when analyzing categorical data to see if there is a relationship between the variables.
Is Chi-square a test of association?
The Chi-squared statistic can be used to test for association.
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 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.
Chi-square test properties and importance?
