Tables & Charts
Tables and charts of means and differences can be built. For example, in the Crocodile Restaurant survey it might be required to see how much men and women of different age groups spend in comparison with each other – either comparing men and women of the same age group or comparing all men in the different age groups and separately all women in the different age groups. This is the same table we showed in the example of means and significances but this time rather than seeing if there is a significant difference, we are calculating what the difference in the means is.
