Applications of Statistical Analyses on Water Quality data and its recent research trends - Statswork

Analysing water quality data entails reviewing and assessing the data to see if any errors were made during the sampling or analysis of the water quality sample or data entry. To detect any issues regarding data, a series of data checks should be performed.

To detect any issues regarding data, a series of data checksshould beperformed. Itincludesdatacheckinginthefirststage,i.e.data entry,whetherthedataiswithintherangeof parameters,dataiswithinthedetectionlimits,etc.

The benefits of graphical representation of datainclude finding the data trend, findingoutliers in the data,etc.

  6. 1.TRENDANALYSIS Itactsasanimportantfactorforwaterqualityanalysissinceithelpstheresearcher understandthe data's variability. Wang et al. (2020) proposed an innovative trend analysis to detect or identify the annualand seasonal rainfall pattern. Data collectionfrom different meteorological stations and compare the proposed methodwith Theil-Sentrend method Mann-Kendalltest.
