Hi guys, today in class we learned about Using Samples & Populations. The key terms in this lesson are:
Sample, convenience, random, stratified, systematic, voluntary response and census. After the lesson Mr.Piatek gave us a sheet about a stratified sample and we did it together as a class. For the work sheet we had to use stratified to breakdown the number of students in grade 9,10,11 and 12 and after that we did a class survey but with different topics.
