Presentation Transcript
At the end of the lesson, the students shall be able to 1.define accuracy and precision 2.differentiate accuracy from precision 3.apply accuracy and precision in real life situation.
Terminologies: 1.Accuracy- It refers to the closeness of the given set of values to the correct values. (bulls-eye) The closer the darts are to the bulls-eye, the more accurate they are.
2.Error- It refers to the difference between the calculated value and actual value.
3.Precision- It refers to the closeness of the values to each other. The nearer the darts are to each other, the more precise they are. 4. Uncertainty- It refers to a usually described as an error in measurement
Accurate or Precise? Tell whether the situations are: A. accurate B. precise C.accurate but not precise D.Not accurate but precise
1.If a thermometer reads 75 degree Farenheit outside and it really is 75 degree farenheit.
2. If the thermometer consistently registers the exact temperature for several days in a row.
3. A refrigerator thermometer is read ten times and registers degrees Celsius as: 39.1, 39.4, 39.1,39.2,39.1,39.1,39.4, and 39.1. However, the real temperature inside the refrigerator is 37 degree Celsius.
Answer: 1.Accurate 2. Precise 3.Not accurate but precise
