A chi square test will give you a p-value. The p-value will tell youifyour test results are significantornot. In order to perform a chi square testandget the p-value, you need two pieces of information: Degrees of freedom. That’s just the number of categories minus1. ...
The results of PCA were plotted using “ggplot2” (Wickham, 2016) package in RStudio v.1.4.1743–4 software. 2.4. Genetic diversity and differentiation To reveal the level of genetic diversity, we investigated the variation pattern of C. tumidissinoda at the group level based on the results...
The chi-square distribution lends itself to the chi-square goodness-of-fit test, as well as the chi-square test of independence of variables. These statistical methods have been known now for well over a century, but they remain taught in schools....
