Bivariate desk: a desk you to illustrates the partnership ranging from one or two details because of the displaying the brand new delivery of just one variable across the categories of an extra variableCross-tabulation: A strategy always to understand more about the relationship anywhere between a couple details which were planned within the a good tableColumn changeable: a variable whoever classes are the articles out-of a bivariate tableRow variable: a changeable whose categories were the fresh new rows off a beneficial bivariate tableCell: the latest intersection of a row and you may a column inside good bivariate tableMarginals: the new line and line totals inside a bivariate table
This will be named bivariate studies. The easiest, most straightforward technique for performing bivariate analysis is by constructing an excellent bivariate desk. We basically reference bivariate dining tables regarding rows and you will columns. Simply put, a table with a couple of rows as well as 2 columns is good 2 x 2 dining table.

You will find all in all, 27, that have ten shedding towards low abilities classification, and you may 17 dropping into the high efficiency group.
