Scatterplots

Scatterplot

A data visualization displaying the relationship between two numerical variables with each point representing a single data point.

Positive correlation

Points on the plot trend upwards from left to right, indicating a positive relationship between the variables.

Negative correlation

Points on the plot trend downwards from left to right, indicating a negative relationship between the variables.

No correlation

Points are scattered randomly across the plot, showing no apparent relationship between the variables.

X-axis

Represents one variable in a scatterplot.

Y-axis

Represents the other variable in a scatterplot.

Best Practices

Guidelines for creating effective scatterplots, including clear labeling of axes, using different colors or shapes for groups, and adding a descriptive title.

Limitations

Constraints of scatterplots such as only showing the relationship between two variables and the inability to establish causation.

Software

Tools like Excel, Python (Matplotlib), R, or online graphing tools used to create scatterplots for data analysis and research purposes.
