Chisquared test is typically used for evaluating strength of association in scenarios where the measurement variables are categorical (example: vehicles classified as twowheelers, fourwheelers etc.). It's also a nonparametric test  in other words, it is "distributionfree". Similar to how correlation coefficient helps interpret strength of association between realvalued variables, Cramer's Vscore from Chisquared test can be used with categorical variables. Degrees of freedom (df) for a chiaquare distribution is 1 less than number of categories (df = number of categories  1). Here's a handy table for how to interpret Cramer's Vscore : References:

Chi is the energy that flows within our body. If you ask me, there are lots of interpretations of it, but Chi is what I am most comfortable in using. I think that the Chinese people really did make a huge thing about it. Not only are they well versed when it comes to this topic, but they are also great at doing it. I hope that I can study their craft more, I want to learn all about Chi.
