You just saw a commercial for the Tread Master, an exercise machine that claims an average weight loss of 10 pounds. A commercial for the Climber, a competing product, claims that only 1 out of 10 users of the Tread Master lost any weight at all. The rest of them gained weight. How can both of these claims be true?
Tread Master could be telling the truth the average weight loss is 10 pounds if they used an average of 10 users to come to the avg weight loss assumption. If you view the attached excel sheet if you take the average of 10 users, one lost 139 pounds, and the others gained 5, 3, 4,1,3,2,1,15, and 5 pounds. Which makes Competitors claims correct as well "only 1 out of 10 users of Trade Masters lost any weight at all. The rest of them gained weight". Both companies portray the data set in a way that benefits their company in the best way.

Both the companies portray the data set in a way that benefits their companies in a better way. Both of them are portraying the truth, the only difference is that their perspectives are different.
- Tread master shows that the average weight loss is 10 pounds because if you find the average, it will be:
Average weight loss= ?NumberofpersonsWeightloss−Weightgained?? =?10139−(5+3+4+1+3+2+1+15+5)?? =?10100?? =10
- Its competitor, Climber, states that only one of out of 10 persons lost weight not all, thus the data is wrongly portrayed.
Thus both the companies are right on this.
