Back

A positive association occurs when an increase in one variable corresponds to an increase in the other variable, resulting in an upward trend in the scatter plot.

Front

What is a negative association in a scatter plot?

Back

A negative association occurs when an increase in one variable corresponds to a decrease in the other variable, resulting in a downward trend in the scatter plot.

Front

What does it mean for a scatter plot to be linear?

Back

A linear scatter plot indicates that the relationship between the two variables can be represented by a straight line.

Front

How can you determine the strength of an association in a scatter plot?

Back

The strength of an association can be determined by how closely the points cluster around a line or curve; the closer the points are to the line, the stronger the association.

Front

What type of data is typically represented in a scatter plot?

Back

Scatter plots are typically used to represent quantitative data for two variables.

Front

What is the purpose of using scatter plots in data analysis?

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that fall far from the general pattern of the data; they can indicate variability in the data or errors in measurement.
