This page will help you familiarize yourself with some of CODAP’s features. Check off each item once you have completed it. Feel free to experiment and try things out! Make sure you’re logged into the Animals Starter File in CODAP before beginning.
Tables in CODAP
1 A table of data is shown here, with the title at the top of the table. What is the title?
2 Move the table to a different location on the screen, then minimize the table (hints: Hovering your mouse over the title. What appears?).
3 Re-expand the minimized table, then add a row - also called a case - to the table. (Hint: Click any of the Index numbers in the left-most column. Look at the menu that appears.) Can you delete that same row? (Note: CODAP will not let you delete an empty case.)
4 Move the Age
column so that it is between Fixed
and Legs
. Click on Age
and choose "Sort Ascending (A→Z, 0→9)" from the drop-down menu that appears.
5 Now try "Sort Descending". How many animals have names that begin with S?
6 Delete a column of the table. (Columns are sometimes called attributes.)
7 Use the "Undo" button in the upper right to get your column back. Do the keyboard shortcuts for Redo (Ctrl-Y
on PC, Cmd-Opt-Z
on Mac) and Undo (Ctrl-Z
on PC, Cmd-Z
on Mac) work in CODAP?
8 Close the table. Get it back either by opening the drop-down menu that appears when you click on "Tables" in the upper left.
9 Create a new attribute. Is the column populated (filled in) or empty?
10 Name your new attribute. What name did you choose?
Graphs in CODAP
11 Click on the "Graph" icon in the upper left-hand corner of the screen. Note: When you first make a graph, the points are randomly positioned!
12 How many dots appeared on the graph? (Hint: How many rows - or cases - are on the table?)
13 Click on a dot. What happens?
14 Can you figure out a way to make different information appear when you click on a dot? (Hint: You may need to move a column!)
15 Drag an attribute (like Weight
, Name
, or Sex
) to one of the graph’s axes - or use the drop-down menu that appears when you click on an axis. Can you make the graph show two attributes?
16 Double click on the background of your graph. What happens?
17 Click on the "Rescale" icon (it looks like four arrows pointing in four different directions) to zoom back out and display all data again.
18 Once a graph shows two attributes, can you change it back to a graph with one attribute?
19 Click and drag any attribute name from the top of any column in the dataset to the center of the graph. When the graph region turns yellow, release the mouse. What happened?
