Error, accuracy & uncertainty
Narrated lesson · press play
Every measurement is a little bit wrong — and a good scientist knows it. This lesson makes you honest about your data: the difference between accuracy and precision, what error and uncertainty really mean, how to spot and handle anomalous results, how to draw fair conclusions, and how to tell random from systematic errors so you can suggest real improvements.
What you'll learn in this lesson
By the end you should be able to (NSSCO Physics 1.2.5):
- Explain the difference between accuracy and precision
- Explain that error is the difference between a measurement and the true value
- Explain uncertainty as the interval on either side of a measured value within which the true value should lie
- Handle and process data, including dealing with anomalous or inconsistent results
- Evaluate results and draw appropriate conclusions in relation to the hypothesis
- Distinguish random errors from systematic errors and discuss trends
- Suggest possible improvements to reduce errors
