Random Errors - II ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],-> Value Probability density -> Mean A typical Gaussian distribution indicating the probability of occurrence for a given value. μ indicates the mean value, while σ denotes the standard deviation. For an ideal Gaussian, 68.2% of the values would lie between 1 σ of the mean value , 95.4% between 2 σ , and 99.7% between 3 σ , as indicated in the above figure.

Systematic Errors - II ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Systematic errors lead to a difference in the actual and measured values. In this simple example, the error can be characterized in terms of a difference in the offset (values at zero) and slope of the two lines.
