Understanding Scatter Plots

What is a Scatter Plot?

• A list of numbers and their squares

• A graph showing the relationship between two sets of data

• A type of pie chart

• A map of stars in the sky

What does a positive correlation in a Scatter Plot indicate?

• No relationship between the values

• All the points are clustered together

• As one value decreases, the other increases

• As one value increases, the other also increases

What does a negative correlation in a Scatter Plot show?

• Both values increase at the same rate

• The points form a perfect straight line

• As one value increases, the other decreases

• There is no correlation between the values

What does it mean if a Scatter Plot shows no correlation?

• All points are clustered in one corner

• Points are randomly distributed with no pattern

• Points are all in a straight line

• Points form a perfect circle

What is an outlier in a Scatter Plot?

• A point where both values are zero

• A point that does not fit in with the rest of the data

• A point that fits perfectly with the trend

• The highest point on the graph

What is a gap in a Scatter Plot?

• A point far away from all others

• An area with no points

• A cluster of points

• The highest point on the graph

What does a cluster in a Scatter Plot indicate?

• A strong negative correlation

• An outlier

• A gap in the data

• A group of points closely packed together

What signifies a strong relationship in a Scatter Plot?

• Points are spread out widely

• All points are outliers

• There is no visible trend

• Points are very close together

What does a non-linear relationship in a Scatter Plot look like?

• All points are on one side of the graph

• Points form a straight line

• Points are randomly placed

• Points form an obvious curve

How can you describe a weak positive relationship in a Scatter Plot?

• There is no discernible trend

• Points are close together and going down

• Points are far apart and going up

• Points are close together and going up
