IB Chemistry: Reliability Part 2

This video tutorial covers IB chemistry skills focusing on reliability and random errors. It explains reliability as the consistency of results in experiments and introduces random errors as unpredictable variations. Using examples like archery and chemical reactions, the video discusses how to measure and improve reliability by increasing trials, removing outliers, and averaging results. It also provides practical applications and sample exam questions to enhance understanding.

In the context of the archery example, explain the difference between a reliable and an unreliable archer.
