“Hypothesis testing is the process used to evaluate the strength of evidence from the sample and
provides a framework for making determinations related to the population,”(Davis, 2006)
Step 1: State your null and alternate hypothesis
Step 2: Collect data
Step 3: Test statistic
Step 4: Deciding if the hypothesis will be rejected or fail to reject
Step 5: Conclusions
Hypothesis tests are often used in clinical trials to determine whether a change of habits, new
treatment, drug, or procedure can have a positive impact on the outcome in patients. For example,
it is recommended to have daily physical activity. Physical activity is essential to the maintenance
of one’s health, as it helps prevent a variety of issues. “Obesity is the most prominent concern, but
according to the Centers for Disease Control and Prevention (CDC) (n.d.), regular exercise can
help reduce chronic and life-threatening conditions.”(Lazarus, 2021) There are a lot more benefits
besides improved health, including lower medical bills and a better way of living.
