variables. The more you drink alcohol, the less functionality of
your liver. The less carbohydrates a person intakes, the lower
their Body Mass Index.
Data can be collected and organized as an ordered pair (x,
y). The data can be analyzed to determine the type and strength of
a correlation and to calculate a regression line in order to make a
prediction.
Use the internet to find a data set of ordered pairs. Key
terms to search: Free Public Data Sets and Medical Data Sets.
