Question

Discuss the reliability of your measurements (use standard deviations,correlation coefficients and any relevant observations for your arguments) and compare your data to typical values found in environmental aquifers or drinking water. You may use the following reference:

National Health and Medical Research Council (NHMRC) 2004, Australian Drinking Water Guidelines 6, URL: http://www.nhmrc.gov.au/_files_nhmrc/publications/attachments/eh34_adwg_11_06.pdf (viewed 26/07/2011).

Explanation / Answer

(first of all i want to mention the above link is not working )

here are different types of measurements are given to compare these are all unit free ...

we can use sd or coeffient of variation to compare the reliability of those measurements ...

sd(pH)=.72

sd(conductivity measurement)=63.28 (omitting over RUs )

sd(oxidation reduction)=23.58

sd(Turbidity)=6.22

in case of drinking water ph level is 6.5 to 8.5 in our data ph is found .72 so i think it is reliable

this conclusion is similar in case of other if our result( that has been found here ) not so differ with the satndard then we will conclude that it is reliable o.w not .....
