Y=X
Line slopes straight up left to right
Y=1/x
u

y=x^3
s
y=square root of x
straight to the right with a slight curve down at 0
Interpreting graphs: 3 questions to ask
- Does its Y value start high or low, and should it?
- What is the slope and what does it represent?
- What is the sign of the y-axis? (helps determine whether will ever cross x axis)

Cohort Study
a longitudinal study observing characteristics (usually risk factors) of members of a cohort across time.
Cross sectional study
the analysis of data collected from a population or sample at one specific time (compared to across a time period for cohort studies).
Case control study
an observational study of individuals in the population with a condition present, and comparison of that group to a control group of persons without the disease in that same population (i.e., reference group).
