I have done a microbial analysis of 50 samples of fresh red pepper sauce for APC, Yeasts and Molds, Enterobacteriaceae, E. coli O157, other E. coli and pH. All samples where collected from what is considered as one general area. What statistical analyses should i run on the collected data to determine any relationships or correlation between the different quality indicators measured in a given sample and it's pH? And what statistical analysis should i run to analyse the different quality and safety indicators of all the 50 samples?
