Other systematic errors occur when equipment is used incorrectly, like reading from the wrong end of the meter stick, or forgetting to subtract the weight of the container when finding the mass of a … 0000079474 00000 n Accuracy refers to the agreement between a measurement and the true or correct value. ‘Life is like a box of chocolates’ is a simile that also compares analogous ideas–the uncertainty and variety in life experiences with the same in a box of chocolates. 0000012423 00000 n nature is presented, we draw without hesitation the accustomed inference.

An analogy is a comparison between two objects, or systems of objects, that highlights respects in which they are thought to be similar.Analogical reasoning is any type of thinking that relies upon an analogy. In both science and law there are fundamentally different kinds of uncertainty at issue. In practice, the random SU is often unknown and estimated from repeated measurements. A value of 12.4 volts is read off the meter. 0000007713 00000 n Accuracy cannot be discussed meaningfully unless the true value is known or is knowable.
