Use statistical software or a calculator to determine the population standard deviation of the data listed in
Question:
Use statistical software or a calculator to determine the population standard deviation of the data listed in Table 8 and the sample standard deviation of the sample data from Example 4.
Approach We will use a TI-84 Plus C graphing calculator. The steps for determining the standard deviation using the TI-83 or TI-84 Plus graphing calculator, Minitab, Excel, and StatCrunch are given in the Technology Step-by-Step.
Data from Example 4
Compute the sample standard deviation of the sample obtained in Example 1 (b) from Section 3.1.
Data from Example 1 Section 3.1.
The data in Table 1 represent the first exam score of 10 students enrolled in Introductory Statistics. Treat the 10 students as a population.
(a) Compute the population mean.
(b) Find a simple random sample of size n = 4 students.
