Python-卡方检验 (Python - Chi-Square Test)

Chi-Square test is a statistical method to determine if two categorical variables have a significant correlation between them. Both those variables should be from same population and they should be categorical like − Yes/No, Male/Female, Red/Green etc. For example, we can build a data set with observations on people's ice-cream buying pattern and try to correlate the gender of a person with the flavour of the ice-cream they prefer. If a correlation is found we can plan for appropriate stock of flavours by knowing the number of gender of people visiting.
