Two students come to you with their maths results from last year. Mike says, “I remember that I got 50 on my final maths test last year”. Ike replies, “That’s nothin’. I got 60 on my last maths test”. Explain to the boys why you don’t know who received the better maths mark.

To explain why we can't determine who received the better mark between Mike and Ike based solely on their scores, we need to consider a few key factors:

1. **Different Test Difficulties:** If the tests Mike and Ike took were of different difficulty levels, their scores wouldn't be directly comparable. For example, a score of 50 on a very hard test could represent a higher level of achievement than a score of 60 on an easier one.

2. **Grading Scales:** The grading scales for the tests could be different. One test might be out of 100, while the other might be out of 80, which affects the interpretation of their scores. Without knowing the maximum possible score or grading curve, we can't fairly compare their results.

3. **Relative Performance:** We also don't know how Mike and Ike performed relative to their peers. A score of 50 might be above the class average for Mike, while a score of 60 might be below average for Ike, affecting how well each actually did in context.

4. **Weighting of the Test:** If these final maths tests were weighted differently in their overall grades (e.g., Mike’s test might be worth 40% of his final grade, while Ike’s test is worth only 20%), their impact on the final result would vary, which could change who performed better overall.

In short, without knowing the full context—such as the difficulty of the tests, the grading scale, class performance, or test weighting—we can't definitively say who received the better mark.

Here are some related questions to consider:

1. How does test difficulty impact the fairness of comparing scores?
2. What is a grading curve, and how does it affect test results?
3. How can the average performance of a class affect an individual score's significance?
4. What is the role of weighted grades in overall performance?
5. Why is it important to consider context when comparing scores from different tests?

**Tip:** Always compare scores in context by considering factors like test difficulty, grading scales, and class performance.
