Descriptor Field by Descriptor Field

Jose Gamez -

The Descriptor Field by Descriptor Field chart is essentially a cross-tab analysis of the relative frequency of member in each sub-group plotted for two descriptor fields—one nested within the other. For example, in the screen shot below, you see ‘Father Work Status’ graphed against ‘PC Reading Change Group.’ The result of the analysis is Chi-square = 3.79 with 4 degrees of freedom—not a statistically significant relationship. This non-parametric statistical analysis is commonly reported in the description of a research project participant population and in discovering how the population may have interacting characteristics that should be identified and considered in the interpretation of study results.
