Background

The Biggest Loser is an American reality TV show that debuted on NBC on October 19, 2004. The show features obese contestants competing to win a $250,000 cash prize by losing the highest percentage of weight relative to their initial weight. Each season of The Biggest Loser starts with a weigh-in to determine the starting weights of the contestants. The starting weight for each contestant serves as the baseline for determining the overall winner.

The number of contestants on the show varies from one season to another: ranging from 12 contestants in the pilot season and as many as 25 contestants in season 11.

The contestants are usually grouped into teams. Depending on the season, a team may have worked with a specific personal trainer, or all trainers may have worked with all contestants. The personal trainers are responsible (in conjunction with medical personnel retained by the show) for designing comprehensive workout and nutrition plans and teaching them to the contestants. The contestants are individually responsible for implementing the principles taught.

The competition rules vary from season to season. Typically, the team that tallies the lowest overall percentage of weight lost in a week is deemed to be the losing team for that week. The losing team must vote for one member of their team to be eliminated from the competition. Usually, at some point in the competition, the teams are dissolved and everyone competes individually. Each week, the person who has the lowest percentage of weight lost at a weigh-in is the contestant who is eliminated.

The season finale features both the contestants remaining on the show and those sent home early; the latter are brought back for the finale. Those sent home early compete for a smaller "at-home" prize of $100,000, while those still on the show compete for a $250,000 prize and the title of "The Biggest Loser." (This means all contestants work toward losing weight for the duration of the show, even if they are eliminated earlier in the competition.)

The lengths of the weight loss competitions have varied, but a typical length has been six or seven months from the initial weigh-in to the televised finale.

Preparation

• Use hypothesis test(s) and graphics to find insights about what type of contestant is most likely to win a Biggest Loser competition? Your analysis must include:
  1. At least one appropriate graphical summary (one of the graphs we learned in class)
  2. Descriptive statistics / numerical summaries of the data
  3. At least one entire hypothesis test (including all the steps)
• Use hypothesis test(s) and graphics to find insights about what type of trainer is most successful? (e.g. who gets better results men trainers vs. women trainers, solo vs team trainers, trainers with lots of experience with contestants vs. relatively little experience, etc.)
  1. At least one appropriate graphical summary (one of the graphs we learned in class)
  2. Descriptive statistics / numerical summaries of the data
  3. At least one entire hypothesis test (including all the steps)
• Provide a paragraph to summarize your findings/conclusion.

Ponder and Prove

• If you analyzed the Biggest Loser dataset for a Lesson 3 Application Activity, go back and compare what you can do now compared to then. Comment on what you have learned and how you have grown.

• For problem 1:

1. How did you decide which of the tools to use?
2. How does the "variable of interest", and whether it is quantitative or categorical, influence which test you use to analyze the data?

• What other hypothesis tests could you use to approach the problem in a slightly different way?
