1. Which of the following are characteristics of a cross-sectional study? A. The study examines the presence rates of patients and not the incidence B. The study indicates a connection and not a risk C. The association measure in this study can be OR d. All the answers are correct 2. What is the difference between a cross-sectional study and an ecological study? A. A cross-sectional study is a study that assesses risk while an ecological study is not B. In an ecological study the sampling unit is a group and not an individual as in a cross-sectional study C. A cross-sectional study is only descriptive, while an ecological study is analytical d. Ecological research is only done on environmental research questions, in the core that cross-sectional research on diseases
good job prof. I have a final test tomorrow please tell me does the ecological study have to be at a specific time for both aspects I mean should they measure the rate of obesity and the cancer at the same time ?? thanks a lot
'three over one' NOT "three out of one" fo computing the denominator of the OR in the bottom table. you mis-speak very often in your enthusiastic haste to teach but such dysfluency distracts from otherwise useful lectures !
Great tutor
