Turn your sample design notes into an editable mind map
Upload a PDF, DOCX, PPTX, text notes, or a photo of a textbook page and get a mind map you can rearrange, expand, and study from.
Why a custom sample design mind map beats a generic one
Most sample design mind maps you find online are fixed images that cover someone else's course, so the branches rarely match your syllabus or your professor's terms. A sample design mind map built from your own readings keeps the vocabulary and emphasis you actually need.
- Start from the sampling chapter in your own textbook, not a generic template.
- Keep each main branch to one decision, such as frame, method, or size.
- Expand a branch only when you can explain its sub-points from memory.
- Redraw the map from blank once a week to check what you actually remember.
Editable branches
Rename, move, or delete nodes so the map matches your course outline.
Explorable structure
Expand and collapse branches to focus on one sampling method at a time.
Built from your files
Start from your own readings and lecture slides instead of a generic template.
How it works
Upload your material
Add a PDF, DOCX, PPTX, plain text notes, or a photo of a page.
Generate the map
DeckOwl pulls out the main branches and sub-points from your text.
Edit and explore
Rework the layout, then expand branches as you review each design.
Sampling design usually splits into probability methods, non-probability methods, sample size decisions, and sources of bias. Seeing those as connected branches makes it easier to explain why a stratified design was chosen over a convenience sample.
Once the map exists, you can edit it into the shape your exam or methods section requires, then use it as a review tool before you test yourself.

Frequently asked questions
How many branches should a sample design mind map have?
Most sampling design topics fit well into four to six main branches, such as probability methods, sample size, and sources of bias. Split a branch only when its sub-points start to crowd each other.
What is the difference between probability and non-probability sampling?
Probability sampling gives every unit in the population a known chance of selection, which supports generalizing results. Non-probability sampling relies on judgment or convenience, so results describe the sample more than the population.
Can I export my mind map?
Exporting is a paid feature, and the Plus plan at $39/year or $7.99/month includes PDF, DOCX, Anki, and CSV export. The free plan lets you study in the browser with 3 generations per month.
Is there a free plan?
