IB Biology IA secondary data requirements

IB Biology IA Source Checker

Biology IA can use primary or secondary biological data, but the source must support real analysis and allow limitations, uncertainty, ethics, and biological relevance to be discussed.

What usually works for Biology IA

Usually strong

Student-collected experimental or observational biological data.
Reliable public biological datasets, ecological databases, gene/protein databases, or government health/environment data.
Peer-reviewed studies used to justify method, variables, or biological context.

Needs review

Datasets with no collection method or unclear units.
Human-participant or organism work without consent, welfare, or safety planning.
A source that only explains biology concepts without providing usable evidence.

Avoid or replace

Unverified AI-generated datasets.
Unsafe culturing, invasive organism work, or medical claims beyond school lab scope.
A copied classic practical with no adapted variable or context.

Examples: strong, risky, weak

Strong

A student-collected enzyme rate dataset with repeats, uncertainty, and controlled variables.

Review

A public ecological dataset with good values but limited information about sampling method.

Weak

A revision webpage explaining photosynthesis.

Where to find better Biology IA sources

If your current source gets a warning, do not just add more websites. Use searches that match the assessment rule and replace weak evidence with sources that can actually carry analysis.

Replacement moves

Use datasets with no collection method or unclear units. only as context unless your teacher confirms they can carry evidence.

Add one source that gives direct evidence for the IA, not just general background.

Full source-pack rules

Evidence must support analysis

Marksy checks whether the source produces data that can be processed, graphed, modeled, or evaluated.

Uncertainty and limitations must be discussable

Secondary datasets are flagged when measurement quality or source provenance is unclear.

FAQs

Can Marksy guarantee that my Biology IA source is accepted?

No. Marksy flags likely suitability risks from published IB-style requirements and source evidence, but your teacher remains the final authority for your school and session.

What makes a source strong for Biology IA?

A strong source is relevant to the actual task, traceable to a clear publisher or creator, cited accurately, and matches the component's source expectations. For this checker, the best fit is usually experimental data or reliable biological datasets.

Can I use AI-generated material as a source?

AI-generated material should be treated as a tool output, not an authoritative source. If you use it, acknowledge it and verify claims through traceable primary, academic, official, or published sources.
