5.1.1.3  Trend results shall be reported every month in a cumulative form for all sample results / locations.
5.1.1.4  The monthly report shall contain the results of the current month and also it must contain cumulative data of the previous dates for the year.
5.1.1.5  To draw meaningful conclusion, from the acquired data, all the results shall be subjected to the basic calculations, (But not limited to these) minimum, maximum and average (mean) and Standard deviation from mean shall be determined.
5.1.1.6  For all the statistical results shall be reported for the current month and cumulative period / year till date.
5.1.1.7  If any data is crossing the limit determined, then the comments must be given in the respective trend.
5.1.1.8  The data obtained can be used in establishment of alert and action limits or in house specifications.
