Biology Skills: Accuracy

The video tutorial covers the concept of accuracy in scientific experiments, focusing on how close experimental results are to the true value. It explains systematic errors, which are consistent, reproducible errors in the same direction, often due to measurement issues. The tutorial provides examples, such as Robin Hood's archery, to illustrate these errors. It discusses methods to improve accuracy, including calibration and correct instrument use, and highlights the importance of instrument resolution. The video also includes sample exam questions to test understanding of accuracy in practical investigations.
