英文摘要	An analysis of the quality of the monthly precipitation data of 42 stations was applied in the Western Center of Venezuela. The consistency of the data was evaluated through homogeneity tests, such as the Mann-Kendall statistic (MK), the correlated Mann-Kendall statistic (MKC), the seasonal Mann-Kendall statistic (SK), the Statistical seasonal correlated Mann-Kendall (CSK), the slope of Sen, the seasonal slope of Sen and five homogeneity tests of the data. A well-localized non-monotonous seasonal trend process was identified. Since the existence of a temporary autocorrelation process was determined, it is concluded that the results obtained in the MKC and CSK statistic are the most successful, in 10 of the seasons they have a seasonal tendency. According to the slope of Sen, a group of 8 stations have a tendency throughout the time series. The results of the homogeneity tests indicate the presence of a maximum of 11 stations with Change Point, however, parametric tests of homogeneity and their nonparametric versions are not comparable, since their statistical nature is totally different.
