Question 1011025: A classroom of 30 students are all measured by height. The heights are as follows: 5.4, 5.5, 6.2, 5.11, 5.2, 5.4, 5.3, 5.9, 5.3, 5.1, 5.10, 5.11, 6.1, 5.6, 5.8, 5.7, 6.0, 4.11, 5.3, 5.7, 6.3, 5.11, 5.2, 5.4, 5.7, 5.3, 5.5, 5.9, 5.6, and 5.10.
The question is:
Describe your survey process. What are some sources of possible bias in
your sample? Alternatively, what did you do to ensure a random sample?
I have no idea how to answer this. Please help!!!
