Enter as follows:
Several columns appear, labeled L1 , L 2 , L3, etc.
L1 = months of temperature (1-12)
After all data is entered correctly, preview the format/range of the graph as follows.
Standards:
A11/T.3 and All/T.20
Objectives:
To graph two different pieces of data from the Chesapeake Bay and to begin to see a Natural Inverse Variation occurring.
Procedure:
Divide your class into groups no larger than five students. Students will enter of Temperature data and Oxygen data into the calculator (preferably the TI-82/83).

The data has just been graphed as a scatterplot. An analysis of the data should begin.
Look at the Temperature and Oxygen.
