What is the difference between parametric and nonparametric tests? Chi-square is used to test differences between a) proportions b) means c) variances d) none of the other three options If H_0: \mu_1=\mu_2 and H_1: \mu_1>\mu_2 . We can test this hypothesis using which on...

Learn the Chi-Square test, its formula, types, and examples in statistics. Understand how to analyze categorical data effectively!
The chi-square (χ 2 ) is a non-parametric procedure used to test hypotheses about the independence of frequency counts in various categories. For example, the data may be the proportions of smokers preferring each one of three brands of low-tar cigarettes or the proportion of people favourin...
When to use a parametric test or a nonparametric test? What is the purpose of a chi-squared test? what question does the test answer? what information about data does it provide? What is the purpose of the chi-square test for independence? Give a practical exampl...
To compare observed samples against a distribution rather than a categorized data set, thechi-square suitable model testshould be applied instead. • If the optionoutputis not included or is specified to beoutput=report, then the function will return a report. Ifoutput=plotis specified, then ...
This is the third installment in the series discussing the different elements of the chi-square test. The analysis for larger (r × c) contingency tables was described in the last issue of this journal. A special case of a larger contingency table involves two rows (e.g. experimental and ...
Chi-Square Test of Independence Part 1 Chi-Square Test of Independence (Introduction) Chi-Square: Independence The chi-square is a non-parametric test - It’s NOT based on a mean, and it does not require that the data are bell-shaped (I.e., Gaussian distributed). We can use the Chi...
The Chi-Square statistics is the widely used non-parametric statistical test used for testing relationships between categorical variables. It describes the magnitude of discrepancy between the observed data and the data expected to be obtained with a specific hypothesis. The Chi-Square test is describe...
