Andy was given data to draw 3 scatter diagrams. He also decided to draw a line of best fit on each one.

**Diagram A**
0 10 30 40 0 2 8 10 20 50

a) What type of correlation is shown in Diagram A?

**Diagram B**
0 10 20 30 40 50 60 70 80 90 100
50 50 40 100 90 80 70 60 40 30 20 10 40 30 20 10

b) Which diagram shows the strongest correlation?

**Diagram C**
(Details of Diagram C are not provided in the text)

c) Which line of best fit should not have been drawn?
Give a reason for your answer.

Answer :

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.

Diagram B because there is no correlation and the strongest is always the positive.

What is Scatter plot?

A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.

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.

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

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

Hence, Diagram B because there is no correlation and the strongest is always the positive.
