topic Subsampling or treatment? in SAS Data Management https://communities.sas.com/t5/SAS-Data-Management/Subsampling-or-treatment/m-p/559095#M17103 <P>Hello,&nbsp;</P><P>&nbsp;</P><P>I am just finishing up a factorial experiment with a split plot design and am unsure if I also have a subsample element or just a treatment.&nbsp;</P><P>&nbsp;</P><P>This is a vegetative propagation experiment in which each plant is a single unit in an individual pot. The main plot was watering, high vs low, and within each subplot were 3 blocks that each contained 20 perlite and 20 vermiculite pots. 10 of each of these were labelled at the experimental set up to be harvested at week 3 or week 5. After week 3, the pots were moved to ensure there were no gaps in the trays between pots with the initial order being preserved.</P><P>&nbsp;</P><P>Basically, I am not sure if the week element should be treated as subsampling or as a planned treatment?</P><P>&nbsp;</P><P>Thanks!</P> Wed, 15 May 2019 18:43:08 GMT Elm1 2019-05-15T18:43:08Z Subsampling or treatment? https://communities.sas.com/t5/SAS-Data-Management/Subsampling-or-treatment/m-p/559095#M17103 <P>Hello,&nbsp;</P><P>&nbsp;</P><P>I am just finishing up a factorial experiment with a split plot design and am unsure if I also have a subsample element or just a treatment.&nbsp;</P><P>&nbsp;</P><P>This is a vegetative propagation experiment in which each plant is a single unit in an individual pot.
