Many recorded signals and data are filled with noise making it difficult to tell what you are looking at. I guess it depends what level of science education you deal with, but when I teach, students look at the figures and graphs presented in the literature. Some of the effects are easy to see, others are very subtle. A basic understanding of statistics is critical for describing how we come to measure phenomena. From statistical mechanics, to understanding co-morbid disease, or computer vision, probability distributions show just how variable most things in the world actually are. If you tried to stop a stopwatch at the 1 second mark many times in a row, very rarely do you actually hit the goal, but if you plot your responses they will cluster around a mean of more or less 1 second. A large part of forming a scientist is knowing how to play in these distributions of samples.
What about the process of science? Framing a good question is hard. Is the question testable? 'What does the universe look like' is an ill posed question for a scientist. What form could the answer possibly take? If you can whittle it down, say 'what does the universe look like in the infrared spectrum.' Ok, this we can start collecting data to address, but can you still say what the answer might look like? The more specific the question, the better. If you can't clearly say what form the answer will take, then how can you expect to find it in the data?
How long have we been searching through SETI data? How will you know what evidence of communication from an extraplanetary source looks like? Is it more likely that we will find false positives, or let actual alien missives go undetected?
I think with regards to what the humanities can contribute to science education, philosophy and framing of questions is huge. Ultimately the scientist and philosopher are starting the from same place - wanting to answer a question, the difference is in how they go about finding the answer. Communication skills can never hurt scientists either - how many of you have tried to pick up a journal article expecting it to make sense on the first read? Anything that can help frame and communicate uncertainty would benefit scholars of science, but I think it naive to imply that these skills and foci are not already taught in science curricula.
