Question

5, Accuracy and precision are important and different aspects of design. For example, a famous accuracy issue occurred with the Hubble space telescope. A high precision tool custom correctly- one very precisely, but inaccurately, shaped e error was only discovered once the telescope was in orbit, rendering it useless for y of the proposed applications. Fortunately, because the error was so precise, correctiv lenses could be installed years later to enable full use of the telescope (essentially giving it ing that all errors in volume measurements are due to the instruments (not to your own human error), how would you rate the precision of each instrument? Is the most designed to grind a mirror into the proper non-spherical shape was assembled in lens was 1.3 mm out of alignment - resulting in a "glasses"). Assum precise instrument also the most accurate one?

Explanation / Answer

SOLUTION

Accuracy is how close you are to the true value. This is asociated with random errors. A random error is always present in a measurement. These errors are caused by the readings of a measurement apparatus or in the experimenter's interpretation of the instrumental reading.

Precision is how close two or more measurements are to each other. This is associated with systematic errors. A systematic error are caused by imperfect calibration of measurement instruments or imperfect methods of observation or interference of the environment with the measurement process, and always affect the results of an experiment.

how would you rate the precision of each instrument?

Good Calibration

Adecuate instrument of observation

Considerate changes in the environment that could affect the medition

Is the most precise instrument also the most accurate one?

Not necesarilly. You may have a precise instrument but inaccurate measurement, also you may have an accurate measurment but inprecise medition for example: and inadecuate calibration of instrument .
