1 1.    What is the  second most favored fruit?
22.      How many students are there in Grade 1F?
33.   If you  ran the school canteen, which fruit will you  stock least?

11.    Pear
2 2.   10
3 3.   Dad, I have a problem with this question!!

What is it?
Canteen is  for everyone, not just  Grade 1F :(

Didn’t  your teacher tell you what is sample data?
Yes she did. But she also told  that sample should be from everywhere. This is only grade 1. How do I know what  big students like? And teachers? And parents?

Well, ideally, the sample should be like that.  Sample should represent the population. But if you end up with a sample like this and nothing else is available, what will you do?

Take more surveys.
What if you can’t do that?

I wont  stock oranges then.
That is  the answer. Decisions have are taken based on the best available information.
