According to the Merriam-Webster Dictionary, accuracy is “freedom from mistake or error: the quality or state of being accurate: the ability to work or perform without making mistakes” ("accuracy," 2014). Precision, however, is “the quality of being precise” ("precision," 2014). That doesn’t really help with the definition much. After subsequently checking the definition for precise it means to be “very careful and exact about the details of something” ("precise," 2014). The most notable difference in the definitions of these two words, according to the dictionary, is that to be accurate it is not necessary to be careful about the details of something as it is to be precise. This seemed to be a bit confusing until it is realized that it is possible to perform without making mistakes while estimating measurements accurately. However, to be precise takes a bit more discipline and a desire to perfect what is being measured with exactness. In society, precision of measurements is especially important in the retail industry. For example, a gallon of gas today costs $3.14 9/10. When filling up at the gas station, gallons of gas are measured to within hundredths of a gallon for precise calculation of the cost. Conversely, crab can be priced at $35.00 a bushel, but the amount of crab in a bushel is not as precisely measured. Instead it is based upon how many crab can fit into the basket, not the number of pounds. The same cannot be said for bottled water however. At the self-service stand, a gallon of water costs $0.30. If one is attempting to refill a five gallon container at a cost of $1.50 it is expected to receive precisely five gallons of water. The water will be precisely measured to five gallons. The amount of water that is actually taken home will depend on how accurately the bottle is placed beneath the spigot and if any is spilled in transit. The five gallon bottle of water is precisely filled. However, when transporting the

    The heart is an incredible muscle. Unlike the brain where a person can continue to be “alive” without any electrical activity, without a heartbeat, a person cannot live.

    2) Explain the difference between precision and accuracy. Suppose you made three different mass measurements of a sugar sample you knew to have a mass of 1 g. How would you know whether or not the measurements were accurate? How would you know whether or not they were precise? Could the three measurements be precise, but not accurate? Explain. Answer: Precision is the reproducibility, under the same conditions, of a measurement; accuracy is the closeness of a measurement to the true value of what is being measured. The three measurements would be precise if they were very close to each other in value; they would be accurate if they were close to the actual 1-g value for the mass of the sample. If the measurements are very close to each other, they are precise, regardless of how close they are to the real value. Therefore, the measurements could be precise, but not accurate.…
