Experiment Step Experiment produces “raw data” – In measured units (volts, seconds, lbs, ….) – Organization determined by recording method (notebook, tabular form, database,….) Take data early to check-out experiment Do some “quick data reduction/analysis” during experiment to see if results look ok. Goal: Assure data set is complete and all information is collected while experiment is still set up. Largely a recording process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
