RELIABILITY OF THE INSTRUMENT WITH CRONBACH'S ALPHA AND VALIDATION OF THE HYPOTHESIS BY ANOVA
Main Article Content
Abstract
The objective of this research is to verify the reliability of the instrument used to collect
the information, applying Cronbach's Alpha, and the validation of the hypothesis
through an Analysis of Variance (ANOVA). Cronbach's Alpha is obtained in Excel. The
survey is used with the questions shown in the Check List, applied in a vehicle
assembly plant. The instrument used and the validation of the hypothesis are subjects of
a research work, referring to the production planning in the vehicle assembler Ciauto
Cia. Ltda. specifically for the HAVAL M4 AC 1.5 TM 5P 4X2 Model, where for the
verification of the reliability of the instrument used a Cronbach's Alpha of 0.57 was
obtained, which indicates that the instrument used has a poor reliability according to the
scale in the Cronbach's Reliability table. As for the validation of the hypothesis by
applying an ANOVA, a calculated F - Fisher of 28.25 was obtained, compared to a
tabulated F - Fisher of 2.996, so the null hypothesis (H0) should be rejected in favor of
the alternative hypothesis (Ha).
