Usually, listing all single items creates a table that is far too large to be comprehensible. Therefore it is common to use a frequency table. In a frequency table, you group your items by the groups or categories that you want to display in the first column and list the frequencies (amounts per category) in the second column. This is what you call a univariate frequency table. If you are dealing with a variable on a quantitative scale, the values in the first column are usually grouped in ranges: a grouped frequency table. It is also possible to display two variables in one frequency table. In such a case you add the second category as column heads and list in the fields the frequencies related to that category. This is called a bivariate frequency table, a two-way contingency table, and in database terms it is known as a cross-table or pivot table.
