A school district implements a costly new reading program and finds a statistically significant increase in reading speeds of words per minute among its students. Apply the concept of practical significance to explain why the school board might decide to cancel the program.
Question: A school district implements a costly new reading program and finds a statistically significant increase in reading speeds of words per minute among its students. Apply the concept of practical significance to explain why the school board might decide to cancel the program.
Sample answer: The school board might cancel the program because an increase of 0.5 words per minute is a trivial effect that lacks practical significance, meaning it does not have enough real-world usefulness or meaningful impact to justify the high cost.
Key points:
- Applies the concept of practical significance to the reading program scenario.
- Identifies the 0.5 words per minute increase as a trivial or weak effect.
- Explains that the result lacks meaningful real-world importance or usefulness.
Rubric: The student should apply the concept of practical significance to explain that the trivial real-world impact of the reading speed increase means the finding lacks usefulness.

Statistical Significance Versus Practical Significance
What does the term 'practical significance' refer to in the context of research findings?
A clinical study finds that a new therapy reduces anxiety scores by 0.1 points on a 100-point scale. Even if the researchers are mathematically certain that this reduction is a real effect and not a fluke, the finding would likely be described as lacking practical significance.
In psychological research, a result can be statistically significant without having real-world importance. Match each research outcome with the label that best characterizes its practical significance based on the meaningfulness of the effect.
Arrange the logical steps a researcher must follow to analyze whether a mathematically reliable finding also possesses practical significance for a real-world psychological intervention.
A clinical psychologist is designing a study for a new treatment for Social Anxiety Disorder. To ensure that any successful result possesses practical significance, which of the following evaluation frameworks should the psychologist construct as part of the study design?
Example of Lacking Practical Significance
Clinical Significance
In psychological research, a finding that is statistically significant guarantees that the result also possesses practical significance in everyday life.
A study of students finds that a new teaching method improves test scores by an average of points on a -point scale, a result that is statistically significant (). A school board reviews this finding and decides not to adopt the method, reasoning that a gain this small would have no meaningful impact on student success. The board is concluding that the finding lacks _____.
Match each hypothetical research outcome with the description that best characterizes its significance based on the relationship between mathematical reliability and real-world utility.
A researcher finds a statistically significant difference in memory recall between two groups, but the actual difference is only points on a -point scale. Although mathematically reliable, this finding is considered to lack _____ significance because the observed effect is too trivial to have any meaningful impact in everyday life.
Order the steps a researcher takes when evaluating a research finding to determine if its statistical significance translates to practical significance.
Define practical significance in the context of psychological research and explain how it differs from a result simply being statistically significant.
Based on the definition of practical significance, what should a clinician conclude about the usefulness of recommending this mindfulness app for everyday practice?
A school district implements a costly new reading program and finds a statistically significant increase in reading speeds of words per minute among its students. Apply the concept of practical significance to explain why the school board might decide to cancel the program.
