My maths exam is coming up very soon, but i dont know whether i need to learn the four sampling methods or not? i dont want to revise any additional information that i might not need for the exam as i have to learn for two other subjects too, someone help?
im also doing my exam soon.. i did it last year in june .. n i remember there was a question in the calculator paper asking about ..
a) what is meant by random sampling. Describe a method Max could use to take his random sample ( 2 marks)
b) a question on stratified sampling.. ( 2marks)
so i guess u should learn about stratified sampling, how to apply it in a question.. and maybe learn the sampling methods, cause anything could come up and you will regret not revising it if it does come up..
