STA 2023 Chapter 1 Calculator Instructions: Generating Descriptive Statistics Ungrouped Data Ungrouped data sets are sets where each value is counted as occurring only once. Thus if the list {2, 3, 5, 7} is considered as ungrouped data, it merely consists of the four numbers 2, 3, 5, and 7. Grouped data, as we shall see later, lists the data values and how many times each of those values show up in the data set. The starting point for generating numerical descriptive statistics is getting the data into a list and then using the 1-Var Stats function to get the statistics. Example: Prices of CDs. The following data values are the prices of the same popular CD sold from ten different discount stores. 12.95, 14.90, 11.57, 14.65, 17.95, 21.25, 12.95, 20.35, 10.95, 25.05 Press the STAT key. Press the number 1 key. Enter the data values into L1. Press the STAT key. Press the ► key to highlight CALC. 1

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
