Chi-Squared Tests in
Ecology
, Learning objective
• 12.3.1.2 use statistical methods for
ecosystem analysis (Chi- sqaured criterion)
, Success criteria
• Outline the purpose of carrying out X2 criterion in
ecosystem analysis
• Review quadrat sampling
• Create the Null (HO) and Alternative (HA) hypotheses
• Calculate X2 value and use X2 value to analyse ecosystem
• Identify degree of freedom and critical (p value) from
statistical tables of X2
• Interpret the results of X2 obtained
• Compare t-test and X2 criterion
