Lab 2. Propagation of Error and Error analysis 2c. Based on the data collected in the table above, student calculates average toss to be 7.35 and standard deviation to be 4.869. One of these two numbers is incorrect. Which number and why? average toss because 9 is correct average toss due to biggest frequency Standard deviation because student forgot to take a square root out of sum average toss because it cannot be a non-integer number Standard deviation because student forgot to divide with 39 before taking square root Lab 2.
