Question

Andy was given data to draw 3 scatter diagrams.

Answer 1

Answer:

A) Negative Correlation. B) C. C) B

Step-by-step explanation:

A:

As the line of best fit is travelling downwards, it is a negative correlation, if the line of best fit is travelling upwards, it is a positive correlation, if the points on the graph are all over the place, there is no correlation.

B:

As there are only three types of correlation, the strongest is always the positive.

C:

The answer is B because there is no correlation and that means that there shouldn't be a line of best fit.
