Best ResponseYou've already chosen the best response.0they will say NO, and if u go to a poor neighborhood and ask whether rich ppl should pay more taxes ppl are more likely to say yes... So both responses are biased

Best ResponseYou've already chosen the best response.0One way to judge the sucess of a movie is to rank it by ticket sales. however, tickets are more expensive today and theatres hold more people than in the past. suggest a way to remove these biases so that past and present movies can be compared fairly.

bahrom7893

Best ResponseYou've already chosen the best response.0well the top option would be make the tickets cheap.

bahrom7893

Best ResponseYou've already chosen the best response.0Not free, because then rich people would think that this movie is trash which is why they are giving away the tickets.. so you would only get responses from the rich

Best ResponseYou've already chosen the best response.0*sorry meant: Not free, because then rich people would think that this movie is trash which is why they are giving away the tickets.. so you would only get responses from the poor people who would take the tickets

bahrom7893

Best ResponseYou've already chosen the best response.0and if the ticket prices were high, then poor people wouldnt be able to afford them and you would get responses from only rich people

bahrom7893

Best ResponseYou've already chosen the best response.0and to minimize bias you want responses from both rich and poor people, u need diversity

Best ResponseYou've already chosen the best response.0a popular television sports show asked people to phone in their pick for the NBA Most Valuable player. with 30 min left in the show, they announce the result to that point. a) how might this announcement affect the outcome of the survey? b) Does reporting the early results make the survey biased? explain why or why not?

bahrom7893

Best ResponseYou've already chosen the best response.0Okay first of all a) you will definitely get biased results, and you always want to avoid them.

bahrom7893

Best ResponseYou've already chosen the best response.0b) Reporting survey earlier would decrease the bias because look, it is the end of the game right, and suppose you were going to vote for player A, but turns out player B scored more goals or whatever u call em in basketball (sorry i hate american sports), so you will end up picking player B if you choose when there's 30 mins left..

bahrom7893

Best ResponseYou've already chosen the best response.0And if you are reporting it early, then player A and B would have equal chances, because you don't know who is going to perform better..

bahrom7893

Best ResponseYou've already chosen the best response.0do you kind of get it? If nothing affected your vote then it would NOT be biased, but halfway into the match, you see one guy is better than the other, so something is affecting your vote

bahrom7893

Best ResponseYou've already chosen the best response.0so now she should NOT have asked her friends who are each others' friends too, because most friends share common tastes, so they all would like comedies, or tragedies or whatever..

B: Let soccer balls be 1 tickets  2 coupons  3, ask whichever they prefer and record the number then see how many counts of each number we have..
