Explanation / Answer

1) Biased Sample:- Your 10 closest friends are not representative of all the people who took the math course.

2)Small sample:- the sample of 4 students is very small to represent all the people who took the course( assuming a lot of them took the course)

3)Using Distorted percentages(Partial Information): -The newspaper Should have mentioned the lowering of income tax percentage.

4)Using Precise numbers:- The instructor is using much more precise numbers knowing that there is a possibility of other errors.

This question is not framed properly and will change the thought of the daughter than what it would have been otherwise.
