Introduction A primary goal of your efforts in this course will be to gather empirical data so as to prove(or disprove) your hypothesis Typically the data that you gather will not directly satisfy this goal Rather, it will be necessary to \reduce\the data. to put it into an appropriate form, so that you can

Quick review 1. Show the reader what s/he needs to see 2. Plan the sequence and directionality 3. Think about the focal point of the graphic 4. Integrate labels units of measurement. and information

To create effective parts/whole or process graphics 1. Show the reader what s/he needs to see. Choose appropriate type of graphic For example, what is the difference between a photo and a drawing?

Experiment Step Experiment produces \raw data? In measured units(volts, seconds, Ibs, .... Organization determined by recording method (notebook, tabular form, database,....) · Take data early to check-out- experiment Do some \quick data reduction/analysis\ during

TOPICS TO BE COVERED Why do error analysis? If we don't ever know the true value, how do we estimate the error in the true value? Error propagation in the measurement chain How do errors combine? (How do they behave in general?)

Why search (and cite) the literature of your field? Credibility: To be sure that your work is based on current, sound researchthe-- best in your field. Focus: To be able to place your work in context. Efficiency: To be sure that you're not duplicating work

Variables 　 Independent Variable: a quantity that you will vary and control E. G. angle of attack, chamber pressure or temperature, coefficient in algorithm, luminosity, gain O Parameter: a quantity that is set or otherwise determined

BASIS FOR MEASUREMENT Whatever exists, exists in some amount Our goals: Measure the appropriate quantity, Measure with the appropriate accuracy, to allow us to assess our hypothesis Some questions:

Elements of Designing an Experiment Goal is to assess your hypothesis The main thing is to keep the main thing the main thing-[Tom Curran, AFRL] The design goal for your experiment is to achieve your objective and satisfy your success criteria. Your HOS are the touchstones for your experimental design
