What is statistical significance and why is it important in education?

Statistical significance helps determine if results from educational research are likely due to chance or if they reflect true effects.

Can you give me an example of how it's used in educational research?

Sure! For instance, if a new teaching method is tested, statistical significance can show if improvements in student scores are meaningful.

How do researchers determine if a result is statistically significant?

Researchers typically use p-values; a p-value less than 0.05 often indicates that results are statistically significant.

What are the limitations of relying on statistical significance?

One limitation is that it doesn't measure the size of an effect, so a statistically significant result might not be practically important.

How can educators apply this knowledge in their teaching?

Educators can use statistical significance to evaluate the effectiveness of their teaching strategies and make data-driven decisions.
