In statistical terms, characterize the shape of a distribution: peaks, symmetry, skewness, variation
1.State how many peaks you would expect for the distribution described.
Voice pitch for the people in the school auditorium consisting of 6 year olds giving a concert, their mothers, and their fathers
Answer
1)One 2)Two 3)Three 4)None
2.Tell which of the following distributions would have the least variation.
Answer
1)Weights of all pet cats
2)Weights of all pets
3)Weights of all children who have a pet cat
4)Weights of all pet dogs
Answer the question, and explain your reasoning.

1.State how many peaks you would expect for the distribution described.
Voice pitch for the people in the school auditorium consisting of 6 year olds giving a concert, their mothers, and their fathers
Answer 3)Three
Why? Because young children, adult female and adult male all have different pitches, so expect 3 separate peaks
2.Tell which of the following distributions would have the least variation.
Answer 1)Weights of all pet cats
Why? Because most cats are about the same size and the closer they are to the mean, the less variation will appear in the distribution.
For dogs, you can go from a tiny chihuahua to a great dane. So, a huge variation.
Same with children depending upon the definition ages newborn to under 18? There will be a huge weight spread.
Make sense?
Have a GREAT day!
