 Thank you so much for all answers, but how to recognize to use the best STAT analysis, I mean to use Descriptive data analysis, or t-test one sample t-test or two samples t-test, or  one-way ANOVA test, or PCA, or multivariate as I have many water parameters and I want to compare it to WHO standards so how to chose the correct and best test, as my water samples are from harvested rainwater tank, any further suggestions, please, Thank you?

Dear Ban,

You have water quality data and like to carry out statistical analyses. First, set your objective and information you like to generate.

Based, on the goal of your work you have to consider the suitable statistical tests. For that what you need - Basic knowledge on statistics - Consult any book that deals with 'statistics and analysis of environmental data'. You should have also clear knowledge on water quality parameters and factors responsible for the particular water quality (chemistry and geochemistry).

See, there are several literature on surface water as well as groundwater in the public domain. As per your objective, you start reading. I am sure, you will understand the subject.

You can start with the literature provided by Dr.Arvind Singh. These are good to understand the basic issues.

Best wishes
