Question

In this lab activity, we will focus on finding statistical measurements using the 1-Var Stats feature of a scientific or graphing calculator.

Explain the difference between the following symbols that may be used to denote a mean: 1. Is there any difference in calculating X and μ for a set of data? Explain. Explain the difference between the following symbols used to denote a standard deviation 2. 3. Why is it necessary for the calculator to report two values for the standard deviation when using 1-Var 4. Stats List the appropriate symbols for the sample variance and the population variance. Be sure to label which 5. one each is
