Understanding effect sizes and variability is important for the general public for several reasons.
First, effect sizes allow us to assess the practical significance of a research finding. For example, a study may show a statistically significant difference between two groups, but if the effect size is small, the difference may not be meaningful in the real world. Understanding effect sizes helps us to determine whether a research finding is truly important or not.
Second, understanding variability helps us to understand the uncertainty of a research finding. All research has some degree of uncertainty, and variability is a measure of how much this uncertainty varies across different samples. Understanding variability helps us to understand how reliable a research finding is (e.g., are the findings an artifact of sampling error?), and whether it is likely to hold true in other populations.
Third, understanding effect sizes and variability helps us to critically evaluate the media's coverage of scientific research. The media often oversimplifies or exaggerates the findings of scientific studies, and understanding effect sizes and variability allows us to see through these exaggerations and understand the true implications of a study.
In addition, understanding effect sizes and variability can help with personal decision making. When evaluating clinical trials or other data-driven research, it's important to understand the size of the effect, and how much uncertainty there is around that effect, in order to make an informed decision about treatment options or interventions.
In conclusion, understanding effect sizes and variability is like the expiration date on milk, just as you wouldn't want to drink spoiled milk, you wouldn't want to base important decisions on flawed or uncertain research. It's an important aspect of being a informed and critical consumer of scientific research. It enables us to more fully comprehend the true significance of research findings, and how certain we can be of those findings. It allows us to more accurately evaluate the media's coverage of scientific research, and also to make better decisions based on scientific evidence.
