What can we conclude from correlation?

Question

I just got my statistics test back and I am totally confused about one of the questions! > A study was done that took a simple random sample of 40 people and measured whether > the subjects were right-handed or > left-handed, as well as their ages. > The study showed that the proportion > of left-handed people and the ages had > a strong negative correlation. What > can we conclude? Explain your answer. I know that we can't conclude that getting older causes people to become right-handed. Something else might be causing it, not the age. If two things are correlated, we can only conclude association, not causation. So I wrote: > We can conclude that many people > become right-handed as they grow > older, but we cannot tell why. That's exactly what association means, but my teacher marked me wrong! What mistake did I make? Is 40 too small of a sample size to make any conclusions?

Answer 1

????

Do not use verbiage like causes, becomes, transforms, etc.

In this instance, THere is a correlation between age and right handed-ness.

That's it.

Just use the word "correlation between" and "in this instance"

Fill in the blank:

In this instance there is a correlation between _____________ and _______________

That's it
