Now we can calculate the X2(chi-square) statistic using the data below.

Note that the two variables can be arranged two ways. The original data table below is one option, and the other option is to represent the drink type in columns and gender in rows. But the latter will make the calculation table very wide so it's less cumbersome to do it with as few column as possible. (Round the answer to 2 decimal places)

Drink/Female/Male/Total count

Drip coffee 5 5 10

Hot espresso drinks 20 15 35

Cold espresso drinks15 20 35

Iced coffee5 10 15

Tea 5 0 5

Total count 50 50 100
