Risk Factor Graphs

When considering risk factors, scientific data uses samples (small set of data):

Sampling

  • A sample of people is taken and the incidence of a risk factor is counted, as well as the incidence of the disease.

Plotting data

  • From the sampled data, a graph (e.g. a bar chart) can be plotted, showing the incidence of the disease for those who have the risk factor and the incidence of the disease for those without.

Plotting data (2)

  • If the risk factor can have a range of risk (e.g. number of cigarettes smoked a day) a scatter diagram can be plotted, showing the incidence of the disease plotted against the number of cigarettes smoked per day.
