explain uncertainty or error in given measurement by suitable example
Answers
Uncertainty is defined as doubt. When you feel as if you are not sure if you want to take a new job or not, this is an example of uncertainty. When the economy is going bad and causing everyone to worry about what will happen next, this is an example of an uncertainty.
Explanation:
A common scapegoat is the catch-all culprit "error." But what do we as instructors mean when we say error? Are we implying that students made a mistake? Are the variations in measurements really errors? To be able to make sense of this situation, students need a firm understanding of measurement uncertainty. They need to know how to determine the measurement uncertainty, and how to preserve measurement uncertainty during calculations. Finally, they need to be able to state results in terms of uncertainty. Given the trend towards teaching science by inquiry, students must be able to understand the role of measurement uncertainty when they use data to draw conclusions about science concepts.
