A decision you can investigate
- You want to test whether a harmless change in word presentation affects recall.
- The procedure needs ethical approval before collecting data.
Build the explanation
- The independent variable 自变量 is deliberately changed; the dependent variable 因变量 is measured.
- Controls, standardized instructions, consent and withdrawal protect both participants and interpretation.
Match the terms to their precise meanings.
Use these definitions in the particular context of Ethical design, data and evaluation.
Work through the evidence
- Compare two approved presentation formats using a justified allocation method. Record recall consistently and retain anonymized raw data.
- Describe the design before selecting suitable descriptive and inferential analysis with the teacher.
Which variable is the dependent variable in this task?
Compare two approved presentation formats using a justified allocation method. Record recall consistently and retain anonymized raw data. Describe the design before selecting suitable descriptive and inferential analysis with the teacher.
Test the limits
- Avoid deception, sensitive topics and unsupported statistical claims. The current IA is a real supervised experimental study.
- For first assessment 2027 the IA becomes a research proposal: do not relabel this experiment as the new requirement.
Which caution belongs to this particular task?
Avoid deception, sensitive topics and unsupported statistical claims. The current IA is a real supervised experimental study. For first assessment 2027 the IA becomes a research proposal: do not relabel this experiment as the new requirement.
The explanation in this lesson makes a conditional claim; relevant context and evidence still matter.
For first assessment 2027 the IA becomes a research proposal: do not relabel this experiment as the new requirement.
Apply and explain your answer
- Which variable is the dependent variable in this task?
- The measured recall score.

The concept and worked evidence support these claims; the stated limits rule out the universal shortcut.
Use the terms precisely
- independent variable: The factor deliberately changed in an experiment.
