<h3>How to determine which of the graph is biased</h3>

From the graph, we have the following highlight

  • The population parameter of graph R is at the right of the distribution
  • The population parameter of graph W is at the center of the distribution

The above means that:

Graph R is biased, and graph W is unbiased
