Difference between Mann-Kendall and Pearsons Correlation to obtain p-value

#1
Hi,

I am carrying out an analysis about Vegetation and Time. I did a simple linear regression and I got the correlation between both variables (Pearsons). Now, I would like to get the significance of the data.

I got the significance (p-value) carrying out "Pearsons Correlation" but my question is: Mann-Kendall analysis and Pearsons Correlation give the same p-value or should be different?

Thank you so much,

Thank you so much,
before to make the linear regression why haven't you calculated the pearson index? It would have been wise to calculate the pearson index BEFORE the linear regression
