Operationalization l.jpg


Conceptual definition l.jpg

Conceptual Definition

  • Essence:

  • The qualities of a thing that give it an identity (author, date, page).

Operationalize gender l.jpg

Operationalize Gender

  • Variable definition:

  • Two mutually exclusive categories of either male or female (author, date, page).

Measurement procedure l.jpg

Measurement Procedure

  • Observation:

  • Inspect the phenotypic differences and record into one of two categories.

Imagery l.jpg

Operationalize sociable l.jpg

Operationalize Sociable

  • Variable definition:

  • The quality of being pleasant, friendly or affable (author, date, page).

Measurement procedure11 l.jpg

Measurement Procedure

  • Survey of humans exposed to rabbits on a 5-point Likert scale measuring perceived friendliness.

Survey questionnaire l.jpg

Survey Questionnaire

  • On a 1 to 5 scale rank what you perceive to be the friendliness of rabbits:



Imagery13 l.jpg


  • Picture a survey questionnaire being administered to a group of subjects that asks questions about rabbit friendliness.

Interval scale l.jpg

Operationalize temperature l.jpg

Operationalize Temperature

  • Variable definition:

  • The degree of hotness or coldness of a body as measured in Fahrenheit degrees (author, date, page).

Measurement procedure16 l.jpg

Measurement Procedure

  • 12 millimeter rectal insertion of a Sentinel Model # SO200 Fahrenheit thermometer for one minute per subject. FDA/GLP sanitary procedures to be followed between subject administrations.

Imagery17 l.jpg


  • Picture a thermometer being placed in a rabbit and held there for one minute before recording the temperature.

Ratio scale l.jpg

Ratio Scale

Operationalize weight l.jpg

Operationalize Weight

  • Variable definition:

  • The measure of heaviness in ounces (author, date, page).

Measurement procedure20 l.jpg

Measurement Procedure

  • Each subject will be weighed on a Bradshaw Model #33110 mechanical scale incremented in ounces.

Imagery21 l.jpg


  • Picture a rabbit being placed on a scale and the weight being recorded.

Propose qualitative methods l.jpg

Propose Qualitative Methods?

  • There have been 4 quantitative definitions and measures.

  • Can we propose qualitative measures for the essence of a rabbit?

Observational technique l.jpg

Observational Technique

Sensitizing category softness l.jpg

Sensitizing Category: Softness

  • Variable definition:

  • The physical characteristic of being smooth to the touch (author, date, page).

Measurement procedure25 l.jpg

Measurement Procedure

  • An expert panel will be convened to conduct a blind tactile observation of the texture of rabbit fur. Based upon a comparison with other textures, they will confer and attempt to reach a consensus as to the relative softness of the rabbit.

Imagery26 l.jpg


  • Picture blindfolded experts taking turns touching the rabbit fur. Once all experts have done this, they remove their blindfolds, get together and arrive by a group consensus as to the texture of the fur.
