Answer:
The third graph
Step-by-step explanation:
Given are 4 graphs and we are to find out which data set shows a positive correlation between its variables
I graph shows that whenever x increases y decreases hence there is negative correlation
II graph does not suggest linear relationship at all hence correlation is irrelevant here
III graph shows a linear trend and also increasing line. WHen x increases y also increases hence this is the correct answer with correlation positive
IV graph does not show linear trend but seem to be parabolic Hence correlation linear will not be relevant.
