The benefit of a cross-sectional study design is that it allows researchers to compare many different variables at the same time. We could, for example, look at age, gender, income and educational level in relation to walking and cholesterol levels, with little or no additional cost. longitudinal study, like a cross-sectional one, is observational. So, once again, researchers do not interfere with their subjects. However, in a longitudinal study, researchers conduct several observations of the same subjects over a period of time, sometimes lasting many years.
The best we can hope to do in drawing a cross section is to come up with an interpretation that is consistent with all the available data. This lab is designed introduce you to the basic techniques of building cross sections.The last problem asks you to âbalanceâ a crossÂ­section, and we will revisit balanced crossÂ­sections in the fold and thrust belt lab. Constructing a Cross Section. 1. Determine the line along which you are going to draw the section.ou can use. the methods we developed in Lab 2 or you can use the handy chart provided with this lab. 4. Draw in structures (faults, folds) and the lithologic units on the cross section so that unit thicknesses are. preserved (in other words, constant) and the cross section units are consistent with the observed dips.
