not a valid study

Step-by-step explanation:

Given that

Kai is conducting a study about the percentage of students with jobs. His school has 2500 students. He asks everyone in his drama class to participate in a survey. He bases his findings on these results.

Just selecting only students in his drama class to form the sample will not give accurate results since samples are not drawn at random. The sample done is convenient sample saving time, but failing to represent the entire student population with jobs.

THe best sample would be group the students with jobs and select from the group at random a sample size proportional to the population size.

No, he is only studying a small percentage out of 2500 kids. His study isn't large enough to count.
