What Is a Scatter Plot and Its Uses?
A Scatter Plot is a graph that represents the relationship between two variables. Generally speaking, the independent variable is plotted on the horizontal (x) axis, while the dependent variable is plotted on the vertical (y) axis.
Scatter Plots are especially handy when it comes to data analysis since:
- It helps explain the trend of the dataset.
- It allows us to see the maximum and the minimum values of the dataset.
- It helps us understand if the relationship between the variables is linear or non-linear.
