1.00 s fell within the range of the experiment.
You can see from the data set that the worst deviation from the average value was: 1.12 - 0.99 = 0.13 s. This is quite
reasonable, factoring in the timing device and the person’s response time. If an experiment is performed well, the
random error, for the most part, should be evenly distributed near the accepted (theoretical) value. The data should
be both precise and accurate.

falsifiable and verified by experiment. - Scientific data is analyst by mathematics. Data will often include errors, which must be included and analyst.
- A hypothesis is an educated guess; a theory is a synthesis of a substantial body of study that is generally
accepted a true, a law is a broad unifying statement usually expressible mathematically. - Unit conversions are based on the idea of multiplication by fractions of equivalent units.
- All measuring tools have a limit to their precision and therefore an intrinsic uncertainty of measurement.
- The last digit of any measurement is an estimate and significant.
- There are two types of error:systematicandrandom. Systematic error is a consistent error that is usually
associated with calibration and random error is associated with the precision of a measuring tool.
