How are the species that characterise sample station groups formed by cluster analysis determined?
Homework Answers
Cluster analysis of the species in given area is a statically analysis that use identify with in the area. Cluster analysis also known as taxonomic analysis or segmentation analysis with the help of analysis identify the homogeneous species and same species in any ecological area or groups.

CLUSTER SAMPLING WITH ESTIMATION Suppose a population of size N is divided into K- N/M groups of size M. We select a sample of size n -km the following way: » First we select k groups out of K groups...
CLUSTER SAMPLING WITH ESTIMATION Suppose a population of size N is divided into K- N/M groups of size M. We select a sample of size n -km the following way: » First we select k groups out of K groups by simple random sampling . We then select m units in each group selected on the first step by simple random sampling . The estimate of the population mean is the average Y of the sample. Let μί be the...

You need to perform gravimetric analysis of a water sample in order to determine the amount of Ag present. List three aqueous solutions that would be suitable for mixing with the sample to perform the analysis b. a. Would adding KNO3(aq) allow you to perform the analysis? Assume you have performed the analysis and the silver solid that formed is moderately soluble. How might this affect your analysis results? C.
