Yep, what Bree said. And some things I have learned as a first year member and a continuous scouter:
First of all, be prepared and it helps to have a paper designated to each robot. I also suggest that you have one person, especially in the instance of a game like this year's, that is solely in charge of monitoring which robot is scoring and where. Other categories on our sheets include the type of drive, and for this year, whether they were a scorer, ramp, lift, or defense, and how well they performed that. Any other strategies you notice them using should be noted as well. I also think that you could have maybe a strengths and weaknesses table. There are so many ways you could do it; you might just have to experiment until you find what works best for your team and what the drive team is happy seeing.
And it helps to organize the papers in a single file folder or something, and put one person in charge of it so you know where it's at, at all times.
It also helps if everyone in the stands or pits scouting knows what they're doing. Plan ahead, and maybe explain things that are not common knowledge.
To be an effective scouter, you also need to remain focused and train the members of your team that will be scouting to not get too distracted by your robot, so that way your data will still be valid.
I hope this helps and if I think of anything else, I will add it.
Oh, and don't forget plenty of pens and pencils.
