The annual data series and the monsoon season or JJAS series for the whole of India as well as for five homogenous regions were subjected to the MK test; Sen's slope values were also computed for all the series. Trends were examined in a two-tailed test at 5% significance level for which the standard Z-value is ±1.96. The results of the test are presented in Table 4.
