Evaluating your model

Referenced Questions

These questions were answered in the previous steps. They are provided here for your reference.

Using what you know about order of operations and previous math courses, look at the formula above and write out a procedure or "pseudo code" that will take a given data set (e.g., 5 numbers) and calculate sample standard deviation. 

Questions

Please answer the questions below.

Grab your graphing calculator and enter the same data set into List 1 (L1). Next, go to STAT --> CALC --> 1 Var Stats to display descriptive statistics. The sample standard deviation will be listed under "Sx". Does this value match your answer to Question 2.1? If it does, move on to question #4. If not, re-write your procedure or "pseudo code" in the text box below. As a reminder, your procedure must take a list of values and using the formula, calculate sample standard deviation. Make sure the output of your procedure matches the calculator output.
