STATEMENT OF THE GENERAL PROBLEM
They have been general
contradictions on the appropriate method to use in the estimating the
variance components of animals. So this problem has led us into this
research to ascertain the relatively best or appropriate method to be
used in estimating these variance components in farm animals.
OBJECTIVE OF THE STUDY
The
major objective of this study is to determine the best method to be
used between the methods enumerated above in estimating variance
components of farm animals.
SIGNIFICANCE OF THE STUDY
A major
significance of this study is to unravel the relatively best methods
among the methods highlighted above with a view to advising animal
breeders, producers and animal researchers on the best method to be used
in estimating variance components as which relatively better method has
generated a lot of controversies over time .
SCOPE OF THE STUDY
The
scope of the study is centered on the methods of estimating variance
components in farm animals, to know which of the methods is relatively
better in estimation.
DEFINITION OF TERMS
Variance: the amount by which something changes or is different from something else.
Estimation: a judgment or opinion about the value or quality of somebody or something.
Traits: a particular quality in someone’s personality.
Genetic: the units in the cells of livings that controls its physical characteristics.
Components: one of several parts of which something is made.
HYPOTHESIS TO BE TESTED
: there is no significant difference between the methods of estimating variance components.
: there is a significant difference between the methods of estimating variance components.
Level of significance: 0.05
Decision rule: reject H0 if p-value is less than the level of significance. Accept H0 if otherwise.
