 PattenTopics1-10.pdf page 17

Dictionary provided conceptual definition of variable not adequate because it does not indicate the precise concrete or physical steps to identify the variable. Must be operational or report is vague, limited usefulness, result in inability to replicate study.

Redefining a variable in terms of physical steps is called operationalizing it.

  • physical arrangements (standing, type of room, gender of researcher, acquainted with?) infinite number of physical characteristics (humidity, wall color, etc)
Definition produced to adequately REPLICATE it, to CONFIRM results.
  • Clear definition, non-ambiguous words (self-esteem = NO, social/work/etc)
Treatments 
  • Verbal praise (type, frequency, conditions)
PRECISE definition of variable = Operational
