What Scatterplot is
A scatterplot is a type of graph used to display the relationship between two variables, typically along the x-axis and y-axis. It is a graph that shows how two variables are related and can be used to identify trends, correlations, and outliers.
Steps for creating a scatterplot:
-
Gather the data: Before creating a scatterplot, you need to have the data points that will be plotted.
-
Choose an appropriate scale for the x- and y-axes: Select a scale that is appropriate for the data being plotted.
-
Plot the points: Plot the data points on the graph.
-
Connect the points: Connect the points with a line or a curve to show the relationship between the variables.
-
Label the x- and y-axes: Label the x- and y-axes with the appropriate units.
-
Interpret the graph: Look for trends, correlations, and outliers in the data.
Examples
- A scatterplot can be used to investigate the relationship between two quantitative variables, such as height and weight.
- A scatterplot can be used to explore the correlation between exam scores and amount of time spent studying.
- A scatterplot can be used to compare the salaries of different jobs in a particular industry.
- A scatterplot can be used to analyze the relationship between the number of hours worked and the amount of money earned.
- A scatterplot can be used to examine the relationship between the number of hours of sleep and academic performance.
