Howto How To Find Percentage Uncertainty From Absolute Uncertainty from 24howtowikies.blogspot.com

A few people have asked me about this, so i thought i'd clarify things. Calculating variance is very similar to calculating standard deviation. Once you know the mean and standard deviation of the data, you can make your bar chart.

There are several problems here. When your graph represents a mesured phenomenon, the accuracy of the measurement is represented graphicaly on your graph, say if you measure voltage and your meter is accurate to ±2%, when you read 100 volt, youre resalt is actually between 98 to 102 volt, sometimes if you have n.

If you are not sure of what to graph, come and ask me, but the general rule is this: To calculate the fractional uncertainty of a piece of data we simply divide the uncertainty by the value of the data.

If the temperature is just read off a thermometer directly, any uncertainty in the temperature is due to the resolution of the instrument. Now we calculate the value with the uncertainties.
