DATA VALIDATION DATA VALIDATION DETECTION OF DATA OUTLIERSDETECTION OF DATA OUTLIERS

Data outliers are extreme (high or low) values that diverge widely from the main body of data set. The presence of one or more outliers may greatly influence any calculated statistics and yield biased results. However, there is also the possibility that the outlier is a legitimate

member of the data set.

Outlier detection tests are to determine whether there is sufficient statistical evidence to conclude that an observation

appears extreme and does not belong to the data set and SHOULD BE REJECTED.

Data outliers may result from----,

FAULTY INSTRUMENTS,ERROR IN TRANSCRIPTION,MISREADING OF INSTRUMENTS,INCONSISTANT METHODOLOGY OF SAMPLING AND ANALYSIS AND SO ON.

These aspects should be investigated and if any of such reasons can be pegged to an outlier , the value may be safely deleted from consideration.

Example 8.9

Concentration measurements for fluoride were measured as 2.77,2.80,2.90,2.92,3.45,3.95,4.44,4.61,5.21,7.46. Use the Q test to examine whether the highest value is an outlier.

Solution:

Q exp = ( 7.46 – 5.21 ) / ( 7.46 – 2.77 ) = 0.51

Since 0.51 is larger than 0.48.the Q exp value for 96% confidence ,there is a basis for excluding the value.
