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?
