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.
