Some of the most common and convenient statistical tools to quantify such comparisons are the F-test, the t-tests, and regression analysis. Because the F-test and the t-tests are the most basic tests they will be discussed first.
What statistical test can be used to measure biodiversity?
The Shannon diversity index is a commonly used measure of diversity. However, you cannot compare the two index values using classic hypothesis tests because you do not have replicated data. The Hutcheson t-test is a modified version of the classic t-test that provides a way to compare two samples.
What are statistical tools examples?
The most well known Statistical tools are the mean, the arithmetical average of numbers, median and mode, Range, dispersion , standard deviation, inter quartile range, coefficient of variation, etc. There are also software packages like SAS and SPSS which are useful in interpreting the results for large sample size.

How to choose the best statistical test for your research?
A challenge that many novice researchers face is deciding on the appropriate statistical test for their research problem or research question. Even experienced researchers or those who have spent time away from statistics may feel a bit rusty and need a refresher.
When to use Fisher’s exact test for statistical analysis?
Again we find that there is no statistically significant relationship between the variables (chi-square with two degrees of freedom = 4.577, p = 0.101). The Fisher’s exact test is used when you want to conduct a chi-square test but one or more of your cells has an expected frequency of five or less.
