| Popis: | Cronbach'salpha coefficient (α), which was developed by Cronbach (1951), is an internalconsistency estimation method, and still remains the most widely used measureof scale reliability. Although reliability analysis is mostly used in thesocial sciences, in this study it is applied to some body measurements for 82head of Saanen kids at third months of age. The independent variables weredetermined 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 toinvestigate whether the explanatory variables constitutes to explain ahomogeneous 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 wasexcluded from the analysis because of decreasing the reliability. As a resultof the reliability analysis, decreasing the number of variables decreased theR2 value and increased the Mean Square Error (MSE). According to this; The R2value for the 4 variables is 75.80% and for the 3 variables 69.50% which islover. In this study, it was determined that the reliability of the variable hadno 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 wholeexplanation for a homogeneous structure. |
