Technical and Operational Definitions

Front

What is a Technical Definition?

Back

A Technical Definition is a precise explanation of a term or concept, often using specific terminology and scientific language, aimed at providing clarity in a technical context.

Front

What is an Operational Definition?

Back

An Operational Definition describes a concept in terms of observable and measurable criteria, often used to assess or evaluate a phenomenon in practical situations.

Example of a Technical Definition: pH

Back

pH (Potential of Hydrogen) is a logarithmic measure of the hydrogen ion concentration ([H+]) in a solution, used to determine its acidity or alkalinity.

Front

Example of an Operational Definition: Learning

Back

Learning is evaluated by test scores, the ability to recall information, or performance improvement in a specific task over time.

Front

What is Speed in an Operational context?

Back

Speed is how fast an object or person moves from one point to another within a given time frame.

Front

Example of a Technical Definition: Temperature

Back

Temperature is the measure of the average kinetic energy of particles in a substance, commonly measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K).

Front

What is Strength in an Operational context?

Back

Strength is assessed by measuring how much weight a person can lift in one repetition (e.g., a one-rep max bench press) or by using a grip strength tester.

Front

Why are Operational Definitions important?

Back

Operational Definitions are important because they provide clear criteria for measurement and evaluation, making it easier to assess concepts in practical situations.

Front

How does a Technical Definition differ from an Operational Definition?

Back

A Technical Definition focuses on precise terminology and scientific explanations, while an Operational Definition focuses on measurable and observable criteria.

Front

Example of a Technical Definition: Force

Back

Force is defined as an interaction that causes an object to change its velocity, measured in Newtons (N).
