Run a two-group reaction time experiment, calculate means and standard error, and decide whether the difference is real.
Design a controlled experiment comparing two conditions, collect enough trials, and use means and standard error to judge whether the difference is meaningful.
Drop stacks of coffee filters, measure their steady fall speed, and show how air drag grows with speed.
