Properly Designed Survey Example: Two soccer teams are about to play in the World Cup and need a ball to play with. In addition, the directors running the World Cup would also like to appeal to the audience by not just choosing a random type of ball to play with but one that they like. However, the ball must comply with the rules and regulations put forth by the directors. With this, the directors found that of the balls typically used in matches, only fifty are suitable for the grandiosity of the World Cup. According to the directors' calculations, putting all fifty in a survey is too daunting and overwhelming to the person being surveyed. The directors chose to only have four balls in the survey so they set up an SRS to decide which balls they should let the audience vote on. They assign each ball a two digit number, from 01 to 50, then those numbers are placed into a random number table, and from that table four sets of two digits from 01-50 will be chosen and any two digits 51 to 99 and 00 will be discarded until four full sets of digits are chosen without any duplicate numbers. If there is a duplicate, a new random two digit number will then be chosen on the random number table. Those four respective balls will be included in the survey the directors put out. To reach the soccer fans, the directors plan to send it by email out to all the past ticket holders of a World Cup match and any qualifying match played to get into the World Cup. This will ensure that there will most likely by hundreds of thousands of responses to most accurately depict which ball is more heavily liked by the fans. The ball with the highest voting will then be the one to be played with in the World Cup final match.
