Note: These Challenge Questions coincide with the Spring 2005 Reports Challenge Question #2 From: by way of Jane Duden Journey North <susamel@brounstein.com> Date: Tue Mar 08 2005 - 09:24:19 EST It is valuable to record "zeros" for every day whales aren't seen because it helps scientists know on what days whales were not visible. It doesn't cause confusion in the data. If they record zeros, it will help them identify data they took when they saw whales and when they didn't. The information will help them with their research. It makes the recording of data more organized and easier to read. Iselin Middle School/7th grade Andrea Joanne Nastacia Jewel Received on Tue Mar 8 09:24:23 2005 Copyright 2005 Journey North.
