Estimated error in recording a data

uncertainty

The measurement with a caliper has a ______________

smaller uncertainty

Uncertainty is also called _______

the "ERROR" because it indicate the maximum difference between the measured value and true value

Used in a context of measurement

accuracy precision

Refers to how close it is likely to be the true value, by writing the number and symbol

accuracy

Also called as r"epeatability' refers to the closeness of two or more measurement to each other

precision

Precision is also called as

Repeatability

Are statictics fluctuations in the measured data due to the precision limitations of the measurement device.

Random errors

Errors are reproducible inaccuracies that are consistently in the same direction

systematic

They comprise all digits that are known with certainly plus the first digit that is uncertain. The position of the decimal point is relevant

significant figures

The single zero conventionally placed to the left of a decimal points in such an expression in never significant It is used to locate the decimal points

significant figures

How many significant 14657.3

1.00006017

0.007347

The answer must contain the same number of decimal places as the term with the least number of decimal

addition and subtraction

The answer must contain the same number of significant figures as the term with the least number of significant figures

multiplication and division

If the figures to be dropped is five or greater than 5, increase by one the value of the last figure to be retained

rounding off numbers

Method of writing or expressing very large or very small numbers into its exponential form

Scientific Notation

Form of Scientific notation

M × 10n

Number greater than or equal to one but less than ten

M - scientific notation

Number of times the decimal points is koved. It can be a positive of negative
