Scientific investigations
What term describes whether a test “measured what it was intended to measure”?
Validity
Students compare the accuracy of these two types of measuring technologies.
Digital and analogue
This type of trial hides information from both participants and researchers.
Double blind trials
Nuclear reactor meltdowns are used to show how events affect this.
Public image of science
This skill involves “collecting, recording and analysing primary data.”
Conducting an investigation
These two scientists investigated peptic ulcers after unexpected observations.
Warren and Marshall
X‑ray diffraction enabled discovery of the structure of this molecule.
DNA
The Mozart Effect is an example of confusing correlation with this.
Causation
Regulation of research includes protecting this type of Indigenous property.
Indigenous cultural and intellectual property
Students “use peer feedback to refine investigative designs.”
Evaluating and improving investigations
These variables must remain constant to ensure a fair test.
Controlled variables
This collider helped confirm the Higgs boson.
LHC
Students compare emotive advertising with claims supported by this.
Evidence‑based scientific data
Comparing space‑exploration costs to poverty and food supply reflects which influence?
Economic and social influences
Selecting appropriate sample sizes relates to this quality of data.
Reliability
Students must justify materials based on “relevance, cost, risk and familiarity.” What part of investigation design is this?
Evaluating reliability and validity
Assessing random and systematic error relates to which investigative concept?
Accuracy
This effect describes how positive perceptions can cause rejection of valid alternatives.
The halo effect
Government budgets and corporate market opportunities are examples of these forces.
Political and economic forces
Using “suitable language and terminology” is part of this skill.
Communicating scientifically
Von Helmont’s plant experiment is an example of investigating “relationships or patterns in identified phenomena.”
Identifying patterns in phenomena
Ethical development of new technologies using Indigenous plant knowledge is called this.
Bioharvesting
Pons and Fleischmann’s cold‑fusion announcement illustrates problems caused by this pressure.
Publish or perish
Vaccination programs and water purification impact this global measure.
Human wellbeing / world health
This investigative quality is judged by checking whether results are “consistent” and whether “measures taken to reduce error” were effective.
