I'm having trouble categorizing whether this graph is moderate, weak or strong. I believe that this is a weak relationship.
I found that the correlation coefficient r=-0.0106, so this tells me that it's a weak relationship. Would appreciate if someone could get back to me!
Homework Answers
You are right! The linear relationship between the variables Age and net sales is very weak.
Here correlation coefficient is very near to zero, which indicates that the variables are independent of each other.That is they are not linearly related or the relationship is very weak.
And from the graph you can see that when Age increases, Net sales doesn't increase the same way. If the linear relationship is strong, then increase in the value of one variable would have ensured increase in the other variable- which is not evident in the graph.

i have this project on statistics and I dont know how to go about it. i sm to pick a topic and it was going to be Age and dementia. please can someone help as i am so frustrated already. In some cases, the relationship between the two variables is a linear one. In this project, you will need to choose a pair of real-world variables, collect data on those variables, and describe the relationship between the variables. To complete...
