what information do you look at to evaluate whether an effect obtained in an experiment is large enough to have practical /clinical significance? also give an example of interpreting practical or clinical significance.

Expert Solution

We use hypothesis testing procedures to check whether an effect in an experiment is large enough to have practical significance or not. For example, a drug manufacturer claims that the drug manufactured by his company for blood pressure control is capable of dropping the blood pressure to 80 to 90, so we can take a random sample of patients who have high blood pressure problem and ask them to have this drug then note down their blood pressure. After that we will run a hypothesis test, if the p-value from the test is less than the level of significance 0.05, we will conclude that the drug has practical significance.

The authors of a paper describe an experiment to evaluate the effect of using a cell phone on reaction time. Subjects were asked to perform a simulated driving task while talking on a cell phone. While performing this task, occasional red and green lights flashed on the computer screen. If a green light flashed, subjects were to continue driving, but if a red light flashed, subjects were to brake as quickly as possible. The reaction time (in msec) was recorded....

The experiment is about whether the concentration of sodium bicarbonate will have an effect or not on the rate of photosynthesis in spinach by recording the time taken by the leaf disks to float in the sodium bicarbonate solution with different concentrations (0.7% and 1.5%) as treatment groups and the distilled water as the control group. Is it possible for leaf disks to float in thecontrol group (Distilled water)? Why do you think the leaf disks floated at different times...
