Finding and Using Health Statistics

Content

Incorporation into Health Subjects

While these examples were somewhat simplified, the test statistics can be used to measure all kinds of subject matter. For example, researchers investing the impact of a blood pressure medication could use the t-test to compare a sample group of patients with hypertension taking the drug to a larger population of patients with hypertension not taking the drug, to determine if there was a statistically significant difference between the two groups. Doctors could use the z-score formula to determine how a patient’s blood sugar level measured in comparison to the average level of other patients of similar age and weight to determine if treatment is needed. These models are the tools healthcare professionals use to make critical decisions and to ultimately advance the field of medicine.
