It says sam test scores for the making period were 60,89,83,99,95,60

Suppose that sams teacher decided to base the marking period grade on the mean. What grade would sam earn? Do you think this is a fair grade explain your reasoning?

sam would earn (60+89+83+99+95+60)/6 = ...

And why would this not be "fair" ???

To find out Sam's grade based on the mean, you need to calculate the average of his test scores. Here's how you can do it:

1. Add up all the test scores: 60 + 89 + 83 + 99 + 95 + 60 = 386.
2. Divide the sum by the number of test scores, which is 6 in this case (since there are 6 scores): 386 / 6 = 64.33.

Therefore, Sam's grade based on the mean is approximately 64.33.

To determine if this is a fair grade, we need to consider a few things. The mean is a good measure of central tendency when the data is relatively evenly distributed and does not have extreme outliers. However, in this case, we see that Sam has two scores of 60, which is significantly lower than the other scores.

If we consider only the mean, the two low scores could potentially have less impact on the overall grade. Some argue that this might not be fair since it may not accurately reflect Sam's true performance. However, others may argue that because the mean takes into account all the scores, it is a fair representation of Sam's average performance. It ultimately depends on the teacher's grading policy and the weight given to each test score.

In summary, based on the mean, Sam's grade would be approximately 64.33. Whether this is considered fair or not depends on the specific grading policy and the value assigned to each test score.
