| dependent variable/dɪˈpendənt ˈveərɪəbl/ | variable dependiente |
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.

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.
- dependent variable: The outcome measured in a study.

Write from a safer design
- One plan tells one group that a quiz is a competition and tells the other group that the quiz does not count. A safer plan changes only the font size of the same word list, with consent, and counts how many words each person recalls.
- Name the independent and dependent variables in the safer plan, and say why the first plan fails. This practice is not the current supervised internal assessment, and it is not the 2027 research proposal.
One plan tells one group that a quiz is a competition and tells the other group that the quiz does not count. A safer plan changes only the font size of the same word list, with consent, and counts the words recalled. Name the variables in the safer plan and say why the first plan fails.
The independent variable is the factor that is changed. The dependent variable is the measured recall. Deception about the task is outside the lesson's limits.
In the font-size design, which statement is right?

Font size is the change. Recall is the measurement. The lesson says not to relabel the experiment as the 2027 proposal.
