Özet:

 


Cronbach's
alpha coefficient (α), which was developed by Cronbach (1951), is an internal
consistency estimation method, and still remains the most widely used measure
of scale reliability. Although reliability analysis is mostly used in the
social sciences, in this study it is applied to some body measurements for 82
head of Saanen kids at third months of age. The independent variables were
determined as X=(x1, x2, x3, x4); the withers height (x1=WH), body length
(x2=BL), chest depth (x3=CD), rump height (x4=RH). As the dependent variable,
sixth month live weight (Y=LW) was taken. Thus, by calculating, it is aimed to
investigate whether the explanatory variables constitutes to explain a
homogeneous structure in whole. The total  
for 4 independent variables is calculated as 0,900. On the other hand,
since the coefficient of CD variable was calculated as 0.908. This variable was
excluded from the analysis because of decreasing the reliability. As a result
of the reliability analysis, decreasing the number of variables decreased the
R2 value and increased the Mean Square Error (MSE). According to this; The R2
value for the 4 variables is 75.80% and for the 3 variables 69.50% which is
lover. In this study, it was determined that the reliability of the variable had
no effect on the model. This may be due to the nature of the data. As a result,
3 independent variables were found to confirm that they form a whole
explanation for a homogeneous structure.
