摘要：Climate variations show the importance of studies to detect trends or changes in hydrometeorological time series. Aiming to analyze the rainfall and the future trend of rainfall in the Goiás, a study was carried out with linear regression and measures of central tendency and dispersion of rainfall from rain. We used 37 rainfall stations with 30 years of data. We used the average monthly and annual precipitation series of historical rainfall data obtained by the National Hydrometeorology, submitted to a preliminary analysis. The statistic calculated the mean, median and standard deviation of rainfall time needed to check the parameters, and observed the dispersion of the sample. Results are presented from the temporal distribution, linear regression analysis and statistics, future trends, and monthly and annual variation of rainfall average.
