The differences between accuracy and precision
“In the field of science accuracy is the form of measurement that calculates the degree of closeness of a quality to its true value. Precision is a unit of measurement that is also referred as the ability to reproduce the same results multiple times” (Taylor, 1997). The differences are within the description, it all depends on what you are looking for within the results of a test for the proper use of these two units of measurements.
Society depends upon the accuracy and precision of measurements for products sold by the retail industry
Today’s society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, the weight of potato’s , or a gallon of oil. These measurements have to be precise and accurate when it relates to how farmers sell their products such as tomatoes, soybeans, milk, peanuts, and cotton, by weight and or in a bulk sale. Like food products gasoline, water, oil, and several other liquid goods sold in quantity and if the measurements not accurately sold per gallon, then the United States government will not retain a profit from the barrel of oil, water, E-85, and several other liquid goods that purchased from other countries. I would have to say that this really is about supply and demand and the ability to generate a profit from the accuracy and precision of the weight and how much to sell an item for in most situations.
Other ways society depends on the accuracy and precision of measurements is within the food industry. If a chef ordered 500 pounds of potatoes because 500 pounds of potatoes will last until the next month and the delivery company only delivers 490 pounds of potatoes then there might be an issue for the restaurant and recipes that a chef can make. The chef also depends on the accuracy and precision of the proper measurement of each ingredient that added to the recipe. If the chef is inaccurate on their measurements then the chef has just wasted products and time due to the inaccuracy of the measurements.
Compare and contrast the accuracy and precision of at least three types of measurements used in your everyday life
To accurately compare and contrast the accuracy and precision of at least three types of measurements that I have used in my life. The first I will talk about how to calculate fuel mileage, gas mileage or fuel economy, is the distance a car can travel on a certain amount of gas. The better a car's gas mileage, the less money you will spend to get around. While EPA estimates for specific makes and models' gas mileage found easily online, your actual gas mileage when driving on the road can vary significantly based on factors like driving habits and road conditions. Even if your car does not have a built-in fuel economy gauge, you can measure your gas mileage based on a few fill ups.
Step one, is go to a gas station and fill your gas tank until the pump
