One undeniable fact that researchers have uncovered concerning MTurk is that participants on Mechanical Turki ar less spiritual than folks at intervals the U.S. population. data concerning the platform will facilitate avoid bias.
Controlling Platform Factors
Some on-line platforms provide researchers restricted management over the information assortment method, whereas others provide researchers nearly complete management.
