Scatter Plots

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

Front

What does a positive correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.

Front

What is the line of best fit in a scatter plot?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, showing the overall trend.

Front

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

Back

The strength of a correlation can be determined by how closely the data points cluster around the line of best fit.

Front

What does it mean if there is no correlation in a scatter plot?

Back

No correlation means that there is no apparent relationship between the two variables being plotted.

Front

How can scatter plots be used in real-life situations?

Back

Scatter plots can be used to analyze relationships in various fields, such as economics, biology, and education.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually represent the relationship between two variables and identify trends.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that lies significantly outside the range of the other data points, potentially indicating an anomaly.

Front

How do you interpret the slope of the line of best fit?

Back

The slope indicates the rate of change between the two variables; a steeper slope means a stronger relationship.
