The Normal Distribution
“Toss” Game
Name: ___________________________________________ Period: _________
Normal Distribution: The normal (bell-shaped) distribution
tells the probability of a number in some context falling between
any two real numbers.
Data Collection: You will attempt to toss an object onto a target
with accuracy. Measure the distance (in cm) between your
object and the target. If your object lands on the target, your
distance is zero cm.
My distance : __________________________
Class Distances:
1.)
Find the mean and standard deviation of your data.
2.)
Calculate ±1σ away from the mean.
3.)
Calculate ±2σ away from the mean.
4.)
Calculate ±3σ away from the mean.
5.)
Sketch a normal curve with the ranges found in Questions 1-4.
6.)
What percent of data falls between ±1σ? According to the Empirical Rule, is this percentage correct?
7.)
What percent of data falls between ±2σ? According to the Empirical Rule, is this percentage correct?
8.)
What percent of data falls between ±3σ? According to the Empirical Rule, is this percentage correct?
