# How can I explain these linear regression charts well on my scientific poster?

I know that these laboratory analysis reports each have a linear regression relationship and two have a positive slope and one has a negative slope. I am taking my first statistics class and want to be able to explain these very well in a research poster I am doing for work. Am I missing any important information? The negative slope indicates that the values are decreasing together negatively. The positive means they are increasing together. The ADL concentration chart does not have a very good relation but there is still a relation.

• "The negative slope indicates that the values are decreasing together negatively". If they 'decrease together' (i.e. one decreases when the other one decreases) they'd have a positive slope. You mean that one decreases as the other increases, which is the opposite of any sense of 'together'. Adding 'negatively' to the end of that doesn't serve to make it less confusing.
