Which scatter plot shows a data set with a positive correlation between its two variables?

Answer 1

The 3rd one.....positive means going up and correlation means close together.

Answer 2

The third graph

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.
