Standard deviation the mean and the mode

The average of a measurement in a CMF MONITOR report is the mean value for that measurement. The standard deviation of a measurement in a CMF MONITOR report is a value signifying the degree of variation that can occur from the mean for that measurement.

A small standard deviation, or small degree of variation, indicates that most of the extracted measurement values are close to the average or mean value. A large standard deviation, or large degree of variation, indicates that the measurement values are widespread in relationship to the mean.

Figure 1shows the relationship of standard deviations to the mean.

The standard deviation is particularly valuable when analyzing average TSO response time, where a high standard deviation can indicate irregular service to the end user.

A mode is generally used in reference to distribution graphs. Modes represent peaks in graphed values. A graph can have any number of modes. All that is required to graph a mode is for the preceding and following values to be less than the mode value.
