The annual precipitation, as measured by the National Weather Service, for Green Ridge, Wisconsin was recorded by environmental scientists interested in climatological changes.

Enter the data all into list 1, use your calculator to calculate the 5# summary.

Stat, edit, stat, calc, 1-var stats.
Make sure the list agrees with the location of your data.

List the 5# summary separating the numbers by commas.
Ex. 3.1, 5.3, 12.6, 15.4, 21.3

The annual precipitation, as measured by the National Weather Service, for Green Ridge, Wisconsin was recorded by environmental scientists interested in climatological changes.

Enter the data, use your calculator to calculate the mean (x-bar) and the standard deviation (Sx).

Stat, edit, stat, calc, 1-var stats.
Make sure the list agrees with the location of your data.

List the mean and standard deviation separated by commas. Round to three places past the decimal point.

4

The annual precipitation, as measured by the National Weather Service, for Green Ridge, Wisconsin was recorded by environmental scientists interested in climatological changes.

Enter the data, use your calculator to create a histogram (Stat, Edit, then 2nd, y=, select a histogram).

Use ‘window’ to clean up the distribution (Xmin=0, Xmax=60, Xscl=5, Ymin= -1, Ymax=8).
Use ‘graph’ to view the histogram.

Describe the histogram, select all that are correct.
Use the list of actual data for your spread (range).
Use the interval to show the center.
Remember to CUSS about the description, so there are four correct answers.
