Imagine a teacher wants to see if studying more hours leads to better test scores. The teacher would look for the correlation between study hours and test scores. A strong positive correlation would mean that the more hours the kids study, the higher their scores get, which is great! If there’s a negative correlation, it would mean that as kids study more, their scores go down, which would be really surprising and probably mean something is wrong. A weak correlation would mean studying doesn’t really change the scores much at all.
Correlation coefficients are an effective tool for determining if the results of a survey or project are strong or weak. In 3–5 sentences, create a situation where you would want to see the correlation between two variables. Would you want a strong or weak correlation? What would it mean if you had a negative correlation? What would it mean if you had a positive correlation? (4 points)
make it simple in a small paragraph and like a kid wrote it.
