Scatter Plot Correlation | Apply your Understanding

What is a scatterplot?

• A diagram that represents the distribution of a single variable.

• A graphical representation of data points in three dimensions.

• A type of data display that shows the relationship between two numerical variables.

• A chart that displays the frequency of various outcomes in a dataset.

What does a positive correlation in a scatterplot indicate?

• The y variable tends to decrease as the x variable increases.

• All data points are scattered sporadically with no pattern.

• The y variable tends to increase as the x variable increases.

• There is no clear relationship between the two variables.

What pattern does a negative correlation in a scatterplot show?

• A diagonal rise from left to right.

• A diagonal fall from left to right.

• A horizontal line across the plot.

• A vertical line across the plot.

How would a scatterplot with no correlation between variables appear?

• Points rise diagonally in a narrow pattern.

• Points fall diagonally in a narrow pattern.

• Points are scattered sporadically with no discernible pattern.

• Points form a perfect circle.

What does a V-shaped scatter plot indicate about correlation?

• Perfect linear correlation

• Strong positive correlation

• No linear correlation

• Strong negative correlation

If a scatterplot forms an 'O' shape, what type of correlation does it indicate?

• Cannot be determined from the shape alone

• Positive linear correlation

• Negative linear correlation

• No linear correlation

What correlation would a straight vertical line in a scatter plot indicate?

• The question is based on a misunderstanding; a straight vertical line does not indicate correlation.

• No correlation

• Perfect negative correlation

• Perfect positive correlation

What might a scatter plot with data clumping in one corner indicate?

• No linear correlation

• Strong positive correlation

• The presence of outliers

• Strong negative correlation

Why might no association plots often appear clustered?

• Due to a strong positive correlation

• Due to a strong negative correlation

• Because all variables are dependent

• Because of random variation or noise in the data

What type of correlation would you expect between the amount of precipitation and the number of umbrellas sold?

• No correlation

• Negative linear correlation

• Cannot be determined

• Positive linear correlation
