Dear fellow users,
I would like to use the Mann-Kendall Test.
Could you please help me interpret the resulting table?

For instance, based on the screenshot in the link above, what is the basis for stating, 'At the 0.05 level, the input data has a significant upward trend'?
Thank you in advance for your kind help. |

Hello,
The Mann-Kendall Test is used to determine if data is monotonic, which is true of any dataset that either never increases or never decreases. I.e. a dataset that is monotonic either tends to go up, or it tends to go down. The M-K statistic is used to tell which direction the data is trending; if it is positive, the data is heading upward and if it is negative the data trends downward.
Since the test resulted in a p-value less than 0.05, the data is considered monotonic.
And, since the M-K statistic came out positive, the data's trend must be upward.
Best,
Nicholas G.
