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?)
