These differences are called participant variables. Participant variables, or personal variables, occur when a subject's personal trait or feeling affects the experiment. In this hypothetical example (see Equation 1), the variables are classified as follows: “RT” is the response variable, “Listener” is the participant variable (random factor) and “Level” (sound level) is a continuous fixed covariate. variable . The tag is the parent element within which all of the survey’s participant sources are nested using separate tags. Participant variables (also known as subject variables) are the differing individual characteristics of participants in an experiment.Participant variables can be considered extraneous variables because they are variables that can influence the results of an experiment but that the experimenter is not studying.
