Module Four Introduction & Overview

Welcome to Module Four

In tandem with measures of central tendency and measures of dispersion,  we use graphs and visuals to describe and display our data.  Statistics can tell us a lot about our data, but visuals can probably communicate more , clearly,  in a small amount of time than text and numbers can.  Together, these techniques can tell a very interesting and compelling story of our data.   Similar to the way  certain central tendency measures are most appropriate for certain levels of measurement,  certain data visuals are most appropriate for certain levels of measurement. To be clearer,  a variable’s level of measurement sets the foundation for what statistics and visuals can be used to best describe the variable. Learning how to make visuals in SPSS  and when it is appropriate to make them is the focus of this module.
