Accuracy and Precision In Measurements

Distinguish between the precision and the accuracy of a
measurement.


Determine the number of significant figures in a measurement.


Express the result of a mathematical operation to the proper
decimal place (addition and subtraction) or to the proper number
of signification figures (multiplication and division).

Be able to round off measurement to a specified number of
significant figures.

Convert a very large or very small number to scientific notation.

Carry out mathematical operations with numbers expressed in
scientific in notation.

Select and apply technology tools for research, information analysis,
problem-solving, and decision-making in content learning.

Measurement is the collection of quantitative data. The
proper handling and interpretation of measurements are
essential in science. Measuremnts contain a unit
and some inherent error.

This unit discusses ways to recognize, estimate and
report the errors that are always present in measurements.
