Pollination is the transfer of pollen from the male parts of a flower to the female parts of a flower of the same species, which results in fertilization of plant ovaries and the production of seeds.
Choose your x and y carefully. Scientists like to say that the independent variable goes on the x-axis (the bottom, horizontal one) and the dependent variable goes of the y-axis (the left side, vertical one).
I am running a linear regression where the dependent variable is Site Index for a tree species and the explanatory variables are physiographic factors such as elevation, slope, and aspect. None were significant, but after including tree age as independent variable, suddenly elevation and slope become statistically significant.
