WebFeb 27, 2024 · There are two main errors that we see using this method: 1) Some impurities and dust that were on the microscope slide (error of about 3%). What I mean by that is that I calculate 3% of white area when theoretically I should get 0% (all black). WebNov 26, 2014 · Accuracy refers to the agreement between a measurement and the true or correct value. If a clock strikes twelve when the sun is exactly overhead, the clock is said to be accurate. The measurement of the clock (twelve) and the phenomena it is meant to measure (The sun located at zenith) are in agreement. Accuracy cannot be discussed …
