D. In a very large study, it was found that Treatment I resulted in success whit

Let’s take a closer look at those answer choices!

The impact of an average weight loss of 1.2 pounds over a year (like in option A) isn’t likely to inspire many people to change their diets, as it’s not a noticeable change in everyday life. In contrast, achieving a 93% success rate in a large study for Treatment I (option D) sounds promising and practically significant, as it indicates effective results that could realistically benefit many individuals needing treatment.

When evaluating significance, it’s crucial to consider the size of the effect and its implications in real-life contexts. For instance, convincing one out of fifty people to quit smoking (B) might not be very impactful in a larger population, while achieving high success rates in health treatments understandably nudges us toward optimism with broader implications. So, if you’re looking for what could genuinely make waves in the realm of health improvements, it’s hard to beat that impressive 93%!
