7.1.2.2 Operationalisation

• What does operationalisation mean?

  Turning abstract concepts into measurable variables
• What is the purpose of operationalising variables in an experiment?

  To make the experiment measurable and replicable
• How would you operationalise an independent variable in a sleep study?

  Specify the number of hours of sleep deprivation
• What are the steps to operationalise a concept?

  1. Identify the concept to measure
  2. Define how to measure it
  3. Specify the units of measurement
• How is "Stress" defined conceptually?

  As feeling tense or worried
• How can hours of sleep be operationalised in an experiment?

  As "4, 6, or 8 hours of sleep"
• What is the primary purpose of operationalisation in research?

  To measure variables precisely
• What is the significance of operationalising both independent and dependent variables?

  It ensures clarity on what is changed and measured
• What does measurability and objectivity refer to in operationalisation?

  Using quantifiable methods to measure variables
• What is an independent variable (IV)?

  The factor you change in an experiment
• Why is operationalising both IV and DV important?

  It ensures the experiment is clear and measurable
• How does measurability and objectivity reduce subjective interpretations?

  By using quantifiable methods for measurement
• How is "Happiness" measured operationally?

  Using a 1-10 self-rating scale
• What does validity ensure in operationalisation?

  Measures accurately reflect the intended concept
• What are the key components of operationalised variables in experiments?

  • Independent Variable (IV): Factor changed
  • Dependent Variable (DV): Outcome measured
  • Operationalisation: Abstract to concrete measures
• How can performance on a math test be operationalised?

  As the "percentage score achieved out of 100"
• How can heart rate be used in operationalisation?

  As a measurable variable for stress
• What is the first criterion for effective operationalisation?

  Clarity and Precision
• Why do dependent variables need clear measurement definitions?

  To ensure accurate performance measurement
• What is an operational definition?

  Specifies how you will measure a concept
• What is a limitation of simplified operational definitions?

  They may not fully capture intended meaning
• How does operationalisation contribute to replicability in experiments?

  It defines variables in specific, measurable terms
• What does lack of generalizability mean in research results?

  Results may only apply to the specific measure used
• Why is comparability important in research studies?

  It allows comparison with other studies
• How can dosage of medication be operationalised in a study?

  As the IV with blood pressure as the DV
• What are the two types of variables that need operationalisation?

  Independent variables and dependent variables
• What are validity and reliability in the context of operationalisation?

  Measures accurately reflect concepts and provide consistent results
• What is a dependent variable (DV)?

  The outcome you measure in an experiment
• What are the criteria for effective operationalisation of variables?

  • Clarity and Precision: Specific definitions
  • Measurability and Objectivity: Quantifiable methods
  • Validity and Reliability: Accurate and consistent measures
  • Consistency and Comparability: Uniform measurements for comparison
• How does operationalisation enhance validity in experiments?

  It ensures measurements reflect the true concept
• What are the key benefits of operationalisation in research?

  • Precise measurement of variables
  • Enhanced reliability through result comparison
  • Clear communication with other researchers
• What is a consequence of inconsistent operational definitions in studies?

  It makes comparing study findings challenging
• What does consistency and comparability mean in operationalisation?

  Uniform measurement across participants for comparisons
• Why is clarity and precision important in operationalising variables?

  It defines variables specifically and unambiguously
• What is a conceptual definition?

  Explains a concept using general terms
• How does consistency and comparability benefit research studies?

  It enables comparisons between different studies
• What does the operationalisation process do?

  Transforms abstract ideas into concrete measures
• What are the key differences between conceptual and operational definitions?

  • Conceptual Definition:
  • Describes a concept in abstract terms
  • Explains general meaning
  • Operational Definition:
  • Specifies how to measure a concept in concrete terms
  • Defines measurement methods
• Why are operational definitions vital for research?

  They ensure reliable and comparable research
• How can stress be measured effectively according to the criteria?

  Using heart rate in beats per minute
