Explain the difference between a statistically significant result and a large or “impressive” effect?

Homework Answers

Answer #1

Usually Statistically significant results are carried out using some statistical tests like normal, t.test etc and are usually checked using p.value. if p.value is less then 0.05 we reject our null hypothesis otherwise accept. There will be always a significant change ( Change can be small or of large magnitude also) in the data over time or between the two groups which are being compared.  

On the other hand if the change is of good strength or very large it will be significant obviously is called impressive.

Effect size and homeless families: A New York Times article reported on the growing problem of homelessness among families (Bellafante, 2013). The reporter wrote that families in a city-run program called Homebase had shorter stays than families not in the program—a difference of about 22.6 fewer nights in a shelter. However, the reporter observed, “Though this is a statistically significant result, it is hardly an impressive one, especially in light of the fact that the average stay for a family...

If P = 0.04, then the result is statistically significant at the 5% level. If P = 0.04, then the result is statistically significant at the 1% level. If P = 0.04, then the null hypothesis is rejected at the 5% level. If P = 0.04, then the null hypothesis is rejected at the 1% level.

Two researchers are arguing about statistical findings. One of them believes that any statistically significant result is important, irrespective of the magnitude of the association between the independent variable and the dependent variables. The other one contends that statistical significance is meaningless if the association is weak. Who is correct? Explain your answer. Offer a hypothetical or real-word example to illustrate your point.
