     A study is to be performed to determine if athletic study help students. You wish approximately 100 students participating.  One group asked all the athletics in Stavig to participate, with 105 agreeing, they then designed a study on those students.  One group posted a request on facebook and got 112 athletes to participate and then they designed a study on those students.  One group went to the Athletic director and he gave them a list of 98 students, commenting that he made sure there were a good collection of first year to fifth year students in the bunch, and that they would all participate. He said he attempted to pick them using the rule that he would pick randomly jersey numbers to select the athletes. They then designed their study.  Order the three groups samples based on the quality of the selection process.  Name the samples. [A]  [B]  [C].  What would you do to get a better sample than these three? 
  
  Solution
the study need to have approximately 100 student athletes .
group B went on to facebook go get the pool of athletes , although they got 112 to sign up for the study but its not a qulity pool of students as we do not know how many of they are still students and if they are even active athletes or not.
Group A went got 105 athletes to participate
and Group C got the list of 98 student athletes from the director of the atletic board and this pool has a wide array of athletes from 1 year to fifth year.
So group C has the best selection process amongst the 3 groups followed by group A and lastly group B .
