Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables; changes in one do not predict changes in the other.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the data points form a straight line or a pattern that closely resembles a straight line.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables and to identify trends, patterns, or correlations.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.

Front

What does it mean if a scatter plot has a cluster of points?

Back

A cluster of points indicates that there is a concentration of data points in that area, suggesting a common relationship or trend.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that lies far away from the other points in the scatter plot, indicating it may not fit the general trend.
