WebThe chi-squared test is a statistical test commonly used for biological hypotheses to determine if the results are statistically significant. We can also define our hypothesis as one-tailed or two-tailed. One-tailed hypotheses are based on uni-directional hypotheses and two-tailed on bi-directional hypotheses. WebChi-square calculators require you to enter the expected frequencies in each group so that it knows what it is comparing against. Here is an example of how to calculate expected frequencies. One common assumption is that all groups are equal (e.g. 605 / 5 = 121 expected per group). This calculator allows for more flexible options beyond just ...
