For the each data table below determine the function that describes the relationship between the two variables by linearizing the data table. For each data table this means:
All of the steps are shown in the YouTube video on the linearization,http://youtu.be/wgSEmMP-eQk. -This is the same video from Page 6 of this section. You don't need to watch it twice.)
Here is a typed list of the steps, mentioned in the video above, to linearizing your data.
- To find Logger Pro on Your windows 7 or 8 computer, press the "windows" button until you see the tiles. Then type, "Logger," and select "LoggerPro."
-
Start a new "Logger Pro" document. To launch "Logger Pro," press the windows button and begin to type, "Logger." Then select "Logger Pro" from the list that pops up on the right.
-
Enter the data into LoggerPro. You might want to press the "A" icon after entering the data to "Auto-Scale" the graph.
- Use the shape and your brain to match the graph up to one of the 5 types of graphs.
- Perform the function you've determined to the "x" values.
(For example if you've determined that the graph represents an square root function, then square root all the "x" data in a calculated column in Logger Pro.
- Plot these values, from the newly created calculated column, on a graph. (See the video above.)
- Using the statistics button, determine the line's slope, y-intercept, and RMSE. (If the RMSE is too big, try a different function and go back to step 4.)
- Create your final science equation. (You will need to make up a variable for the concept listed. Just pick a letter that makes sense.)
- Save the document onto your computer. Start a new Logger Pro document for each data table.
- When working with a group, move your LoggerPro file to the shared lab folder on the Google Drive.
