Validation of Crombach's Alpha, measures of central tendency and dispersion of an original instrument on the choice of university major in Fresnillo, Zacatecas, Mexico (2022)

With the double purpose of evaluating the reliability of the original instrument and the frequency distribution that emanates from the opinions expressed by the university students of Fresnillo, Zacatecas, Mexico, in the year 2022, about their opinion on the outstanding attributes in the choice of career. university. Crombch's alpha analysis, measures of central tendency and dispersion are carried out. By surveying 445 students of higher level in the mineral, on six theoretical dimensions related to the failure of titration, the positive statistical validation of the original instrument was obtained from the exercise, with a general grade of .968 Crombach's alpha, applied in a subject and population unprecedented, as well as the swings in the frequency distributions of the students' opinions. From there, the results of future tangential studies can be legitimized; adequately discriminate and strengthen the internal consistency of the measurement instrument; adopt the most convenient descriptive, comparative, correlational and factorial methodologies at the following statistical levels, thereby generating new questions and greater context to the vocational issue in the region.
