Appendix II

Data analysis
and interpretation of result

Objective I

To find out whether environmental degradation exists
in Afiesere

Step I: State Hypothesis

Ho: Environmental degradation does not exist in
Afiesere community

Ha: Environmental degradation exists in Afiesere
community

Step II: Choose Alpha (α) and Degree
of Freedom (df)

df = (R – 1) (C – 1)

= (3 – 1) (2
– 1)

= 2 x 1 = 2

df = 2

Where R = Row, While C = Column

α = 0.05 = 5.991

Table I: Response to existence of environmental
degradation in Afiesere

S/N	QUESTIONS	YES	NO	TOTAL
1	Does environmental degradation exist in Afiesere?	215	35	250
2	Does habitat fragmentation cause environmental degradation in Afiesere?	195	55	250
3	Does environmental degradation occur as a result of domestic and industrial activities?	240	10	250
TOTAL		650	100	750

Step VI: Applying Decision Rule

Since X2
calculated value = 35.219 is greater than table value of 0.05 = 5.991 at 2 df,
it shows that environmental degradation exists in Afiesere Community.
