Description
A student receives test scores of 62, 83, and 91. The student's term project is 88 and her homework score is 76. Each test is worth 20% of the final grade, the term project is 25% of the final grade, and the homework grade is 15% of the final grade. what is the student's mean score in the class?
Explanation & Answer
Each test score (62, 83, 91) are worth 20% so they have the weight 0.2.
Term project score (88) is worth 25% so it has weight 0.25
Homework score (76) is worth 15% so it has got weight 0.15
So here (weighted) mean score = weight*score = 0.2*62+0.2*83+0.2*91+0.25*88+0.15*76 = 80.6
Mean score is 80.6
