Analyze The Data

"Okay, this is where you show me that you're not just a muscle-bound raft jockey! What does the data tell you about the health of your river?"

Once your data is entered into the on-line database, the fun begins! Here's where you use your brainpower to make sense of all those numbers.

Charting

In the "River Data and Maps" section of this web site, choose "Graph Collected Data" to work with all the river data entered by the thousands of students before you. You'll need to choose and graph the data best suited to understanding the health of your river.

Comparison

Compare the chart trends and look for connections between different abiotic and biotic factors. You can compare any sets of data that you think might help you understand the river.

• Or, is the numbers of stonefly nymphs related to dissolved oxygen?
