Answer 2

1. D, this is convenience sampling as it is the easiest sampling method to perform (ie you don't have to worry about who/what to select)


2. C, it's stratified since the two strata are males and females


3. B, volunteer because the participants have to willingly come forward (and it's not random)


4. A, this is systematic because you're selecting every fourth teacher (so there's a rule/pattern going on here)
