Scatter Plot Practice

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 the line of best fit represent in a scatter plot?

Back

The line of best fit represents the trend of the data points in a scatter plot, indicating the general direction of the relationship between the variables.

Front

What is a positive correlation?

Back

A positive correlation occurs when an increase in one variable leads to an increase in another variable, resulting in a rising trend in the scatter plot.

Front

What is a negative correlation?

Back

A negative correlation occurs when an increase in one variable leads to a decrease in another variable, resulting in a falling trend in the scatter plot.

Front

What does 'no association' mean in the context of scatter plots?

Back

'No association' means that there is no discernible relationship between the two variables being plotted; the data points do not show any clear trend.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis in a scatter plot, typically representing the independent variable.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis in a scatter plot, typically representing the dependent variable.

Front

How do you determine the correlation from a scatter plot?

Back

You determine the correlation by observing the direction and pattern of the data points: a rising pattern indicates positive correlation, a falling pattern indicates negative correlation, and a random pattern indicates no correlation.

Front

What does it mean if the data points are tightly clustered around the line of best fit?

Back

If the data points are tightly clustered around the line of best fit, it indicates a strong correlation between the two variables.

Front

What does it mean if the data points are widely scattered around the line of best fit?

Back

If the data points are widely scattered around the line of best fit, it indicates a weak correlation between the two variables.
