P-value

A statistical measure that helps researchers determine the significance of their research results, indicating the probability of observing the collected data, or something more extreme, if the null hypothesis were true.

Resamples Without Replacement

Resampling without replacement involves selecting subsets of data where each sample is only chosen once for inclusion in any subset.

Proton Spin Decoupled

A technique in NMR spectroscopy where the coupling between protons is removed to simplify the spectrum.

Distinct Quartets
