Week 11
There are two frequency tables that can be used to calculate the Chi-squared test statistic by hand for this week. StatKey also has the Favourite Skittles Flavour data preloaded in the Chi-squared Goodness-of-Fit tool and the Handedness vs profession data preloaded in the Chi-squared Test for Association tool. Note that the pre-loaded data in StatKey is slightly different to the table in this .csv file and the textbook.
You cannot upload a frequency table into the Chi-squared tools in StatKey, it requires the data to be listed as cases in rows with variables in columns.
