Math Problem Statement
All products in a factory are tested.
Each batch of products receives an overall score that shows how well it did in the tests. The higher the score, the better the batch of products.
This list shows the scores for all the batches from last month.
8.4 6.3 7.5 4.7 6.7 7.4 7.8 8.1 6.5 7.1 5.9 3.4 5.6 6.8 7.6 8.1
Tahir wants to report on the average score achieved last month. He wants the results to look as good as possible.
Should Tahir use the mean, median or mode?
