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 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 is the 'Line of Best Fit'?

Back

The 'Line of Best Fit' is a straight line that best represents the data on a scatter plot, showing the general direction of the data points.

Front

How can you identify a scatter plot with no correlation?

Back

A scatter plot with no correlation shows data points that are randomly scattered without any discernible pattern or trend.

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, correlations, or patterns in data.

Front

What does it mean if a scatter plot has a steep slope?

Back

A steep slope in a scatter plot indicates a strong relationship between the two variables, whether positive or negative.

Front

How do you interpret the data points in a scatter plot?

Back

Each data point in a scatter plot represents an observation, with its position determined by the values of the two variables being compared.

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, potentially indicating an unusual observation.

Front

How can you make predictions using a scatter plot?

Back

You can make predictions by analyzing the trend shown by the data points and using the 'Line of Best Fit' to estimate values.
