Introduction to Scatter Plots

Front

What is a scatter plot?

Back

A scatter plot is a type of graph that uses dots to represent the values obtained for two different variables - one plotted along the x-axis and the other plotted along the y-axis.

What does it mean when points in a scatter plot form clusters?

Back

When points in a scatter plot form clusters, it indicates that there are groups of data points that are close to each other, suggesting a relationship or pattern among those points.

Front

What is a positive correlation in a scatter plot?

Back

A positive correlation occurs when an increase in one variable leads to an increase in another variable, resulting in a pattern that slopes upwards from left to right.

Front

What is a negative correlation in a scatter plot?

Back

A negative correlation occurs when an increase in one variable leads to a decrease in another variable, resulting in a pattern that slopes downwards from left to right.

Front

What does no correlation mean in a scatter plot?

Back

No correlation means that there is no apparent relationship between the two variables, and the points do not show any clear pattern.

Front

What are the three types of association in scatter plots?

Back

The three types of association in scatter plots are positive correlation, negative correlation, and no correlation.

Front

How can you identify a slight upward trend in a scatter plot?

Back

A slight upward trend can be identified when the points generally rise from left to right, indicating that as one variable increases, the other variable also tends to increase.

Front

How can you identify a slight downward trend in a scatter plot?

Back

A slight downward trend can be identified when the points generally fall from left to right, indicating that as one variable increases, the other variable tends to decrease.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually display the relationship between two quantitative variables, helping to identify patterns, trends, and correlations.

Front

What does it mean if a scatter plot has a linear association?

Back

A linear association means that the relationship between the two variables can be represented by a straight line, indicating a consistent pattern.
