Statistics can be difficult, but with many online websites available, we can easily perform simple statistics. In this article, we have taken up a website to show how to do a Chi-square test online. The website also has many other functions which one can use. The website which has been referred here is https://www.socscistatistics.com/tests/Default.aspx [Figure 1a] and [Figure 1b].

Here, we have tried to find the relationship between sex (male or female) and obesity on this website and demonstrated how to use this website to calculate the Chi-square. The figures are self-explanatory [Figure 2] and [Figure 3].

This website[1] contains a number of statistical functions[2] which are required in biological sciences[3],[4],[5],[6],[7],[8],[9],[10],[11] and can be used by all students for free.
