Activity 2: Error and Error Propagation



“An error does not become truth by reason of multiplied propagation, nor does truth become error because nobody sees it.” - Mahatma Gandhi

Errors are common in life.  We learn our mistakes through errors we do or experience everyday.  In the field of science, errors are defined as the closeness of values denoting how far a measured value is with respect to a reference value.

In this session, I was able to understand full the concept of uncertainty, the error between measured values.  Also all about deviations, relative and absolute error.  There are so many formulas to understand and I should grasp it well.  

By the end of the session, I was able to cling on the knowledge I should have to meet our objectives of the day. With my group, we were able to identify the type of error involved in an experiment; Distinguish between accuracy and precision of a measuring device; and report values that result from operations on best estimates.

The whole session was fun.  The real fun part was the group errors we committed while answering the activity :)) 

I'm looking forward to acquiring more knowledge through the world of physics :)
