Claudio Pereira

Hi, depends if scores and metrics distribuition are normaly distribuited or not, and if sampling was random selected.

Sam Eneje

Thank you@Claudio Pereira

Valentine Joseph Owan

Parametric statistical tests are used based on the assumption that the data obtained were normally distributed while non parametric should be used when the data are not normally distributed. Your choice will depend on any of these assumptions above.

Cheers

Sam Eneje you must run normaly test such as Kolmogorov-Smirnov or Shapiro-Wilk.
