Which of the following parameters can be used to enlarge or reduce the size of data points in a scatter plot?

The size of data points in a scatter plot can be adjusted using the 's' parameter in many programming languages like Python, particularly in libraries such as Matplotlib. The 's' parameter stands for size. By increasing or decreasing the value of 's', you can enlarge or reduce the size of the data points respectively.

Here is a step by step guide on how to do it:

1. Import the necessary libraries. For instance, in Python, you would import Matplotlib like this: import matplotlib.pyplot as plt.

2. Create your scatter plot. You can do this by calling the scatter function on plt and passing in your x and y values. For example: plt.scatter(x_values, y_values).

3. To adjust the size of your data points, add the 's' parameter to your scatter function call. For example: plt.scatter(x_values, y_values, s=100). This would make your data points larger than the default size.

4. Finally, display your plot using plt.show().

Remember, the value you pass for 's' is relative. A larger value will result in larger data points, and a smaller value will result in smaller data points.
