Consider the following weighted mean example:

The scores on a Mid-Term Exam for a sample of 50 statistics students are summarized in the following table.

Table Description automatically generated

The professor who gave the midterm wanted to get an idea of the average class grade on the midterm for course reevaluation. Here, one would determine x¯=74.8 (try it yourself before proceeding). This would be our weighted mean.

For this discussion, I want you to come up with your own weighted mean problem related to your major and solve it. First, create a labeled table of values (use mine as a reference), then, provide the sample size, and lastly, determine the weighted mean. Why would someone want to know the weighted mean in your example from your major?
