There are six separate, unrelated claims below, and ALL OF THEM ARE WRONG! Your job is to figure out why by looking at the data.

Data Claim What’s Wrong

1

The average player on a basketball team is 6′1″.

“Most of the players are taller than 6′.”

2

Linear regression found a positive correlation (r=0.42) between people’s height and salary.

“Taller people are more qualified for their jobs.”

3

linear regression plot: y=12.234x + -17.089; r-sq: 0.636

“According to the predictor function indicated here, the value on the x-axis will predict the value on the y-axis 63.6% of the time.”

4

Bar Chart: Sasha and Wade are 1 years old, Felix is 16 years old, Booboo is 11 years old, Maple is 3 years old, Nori and Nibblet are 6 years old

“According to this bar chart, Felix makes up a little more than 15% of the total ages of all the animals in the dataset.”

5

histogram: with 3 animals weighing 20-40 pounds, 4 animals weighing 40-60 pounds, 2 animals weighing 60-80 pounds, 2 animals weighing 80-100 pounds, 1 animal weighing 100-120 pounds, 1 animal weighing 120-140 pounds, no animals weighing 140-160 pounds, 2 animals weighing 160-180 pounds

“According to this histogram, most animals weigh between 40 and 60 pounds.”
