Big Five personality traits are broad patterns of thoughts, feelings, and behavior. Many people look for a big five personality test with radar chart to understand their profile at a glance. Short statements invite quick ratings so results reflect how you see yourself now.

You read a statement and pick how accurate it feels from very inaccurate to very accurate. Totals for Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism are shown together so you can compare strengths and lighter areas with context notes and next steps.

For example, a person might see strong Conscientiousness and milder Extraversion, then plan focused work blocks and choose smaller groups for collaboration. Scores describe tendencies, not abilities, so treat them as a guide for reflection and planning.

Your responses stay on this device and are not sent anywhere. Answer in a calm setting, use the same approach each time, and avoid racing through items for the clearest signal.

This tool provides informational estimates and does not substitute professional advice.
Results do not constitute a clinical diagnosis.

Technical Details:

The inventory uses 120 public‑domain items from the International Personality Item Pool, rated on a five‑point scale. Items load a single time and reflect a current snapshot rather than long‑term tracking. The five domain totals are Openness (O), Conscientiousness (C), Extraversion (E), Agreeableness (A), and Neuroticism (N), each based on 24 items.

Each statement contributes a scored value. Normal items use the chosen rating. Reverse‑keyed items invert the scale so a higher rating counts as lower endorsement of the domain. A domain total is the sum of its 24 scored items. Emotional Stability is represented as the complement of Neuroticism.

Results are grouped into bands using fixed raw‑score cutoffs defined in the package. Low indicates lower endorsement on the domain, average sits between the cutoffs, and high indicates stronger endorsement. Values very near a cutoff are best read in context with the other domains.

Comparisons are meaningful within this instrument when you answer under similar conditions. Facet‑level scores are not computed here; interpretation is at the domain level only.

TD = ∑ i∈D si
si = xi if item i is not reversed si = 6−xi if item i is reversed
S=120−TN
Symbol Meaning Unit/Datatype Source
xi Raw rating for item i points 1 to 5 Input
si Scored value after any reverse key points 1 to 5 Derived
TD Domain total for D ∈ {O,C,E,A,N} points 24 to 120 Derived
S Emotional Stability (complement of N) points 0 to 120 Derived
Worked example. Suppose Neuroticism has 12 normal items at 2 and 12 reversed items at 4. Normal sum = 12 × 2 = 24. Reversed sum = 12 × (6 − 4) = 24. Total TN = 48, classified low. Emotional Stability S = 120 − 48 = 72.
Band Lower Bound Upper Bound Interpretation Action Cue
Low 24 48 Lower endorsement of that domain. Lean on complementary strengths and routines.
Average 49 84 Midrange endorsement. Adjust habits based on context and goals.
High 85 120 Stronger endorsement of that domain. Use strengths while watching for overuse costs.

A balance note summarizes spread across O, C, E, A, and S. It is “even mix” when maximum minus minimum is at most 12, “mild tilt” when at most 24, and “distinct peaks and valleys” otherwise.

Units and precision. Domain totals are integers. Percent displays round to the nearest integer. The decimal separator shown in text is a period when present.

Networking and storage behavior. Processing is browser‑based, responses are encoded into the r parameter for persistence and sharing, and no requests are sent to servers.

Performance. Scoring and rendering are linear in the number of items with negligible memory overhead for 120 responses.

Diagnostics and determinism. Identical inputs produce identical results. The encoded r value fully determines the profile.

Security considerations. Treat the r parameter as sensitive when sharing, as it encodes your answers in a compact form readable by others.

  • Assumptions and limitations.
  • Raw totals use fixed cutoffs, not percentiles or norms.
  • Facet‑level scores are not calculated.
  • Self‑report can shift with mood and context.
  • Reverse keys assume a consistent understanding of wording.
  • Sharing the URL shares responses via the r parameter.
  • One pass collects a snapshot, not a stable trait estimate.
  • Heads‑up High or low does not imply good or bad.
  • Device, time of day, and interruptions can bias answers.
  • Edge cases and error sources.
  • Partial completion yields incomplete totals until all 120 are answered.
  • Invalid r strings are ignored, leaving current selections unchanged.
  • Whitespace or stray characters in r make decoding fail.
  • Very similar items may invite patterned responding.
  • Rapid clicking can mis‑select an option.
  • Reading on small screens may increase fatigue.
  • Ambiguous wording can be interpreted differently by readers.
  • Copying results without context can mislead others.
  • Browser add‑ons that rewrite URLs can break r persistence.
  • Clearing history can remove the encoded state.

Scientific background. The items are from the International Personality Item Pool and align with the five‑factor model. “IPIP‑NEO‑120” denotes the 120‑item public‑domain form.

Privacy and compliance. No data is transmitted or stored server‑side. Use results responsibly and avoid sharing sensitive responses without consent.

Step‑by‑Step Guide:

Big Five scoring converts your ratings into five domain totals you can compare at a glance.

  1. Read each statement carefully and answer with 1 to 5.
  2. Finish all 120 items to reveal results.
  3. Review domain totals and the chart to spot patterns.
  4. Read the highlights and next steps to plan actions.
  5. Optionally copy or download your answers for reference.
  6. Repeat on another day to compare consistency.
Example. A total of 90 on Conscientiousness suggests strong planning and follow‑through, while 45 on Extraversion suggests preferring quieter settings.

Use the pattern that emerges to make one small change this week.

FAQ:

Is my data stored anywhere?

No. Scoring runs on your device. Answers are encoded in the page address as r so you can keep or share them if you choose.

Avoid sharing the address if you want to keep responses private.
How accurate are these scores?

They are raw sums from this instrument with fixed cutoffs. They show relative emphasis across domains, not a clinical measurement.

What ranges do totals use?

Each domain totals 24 to 120 points. Bands are low, average, and high using cutoffs at 48 and 85.

Can I use it offline?

Yes. After the page loads, scoring and charting work without a connection.

Does this include facet scores?

No. Items reflect 30 facets but only five domain totals are computed here.

How do I share my results?

Copy the page address that includes r. Anyone with it can reconstruct your answers.

What does a borderline result mean?

Values near 48 or 85 are close to a band edge. Read them in context with your other domains and current goals.

How do I export my answers?

Use the copy or download options in the answers section to keep a CSV or create a document summary.

Is there any cost or license?

Items come from a public‑domain pool. You can use the assessment for personal or educational purposes.

Troubleshooting:

  • No results after finishing. Scroll to the end and confirm all items are answered.
  • Chart not visible. Resize the window or reload after answering all items.
  • Shared link shows different answers. The r value may be missing or trimmed.
  • Buttons do nothing. Check that pop‑up or download blockers are not active.
  • Accidental clicks. Revisit the item and re‑select your intended rating.
  • Slow device. Pause a moment after completing; the chart appears once totals are ready.

Advanced Tips:

  • Answer at a similar time of day when comparing runs.
  • Take short breaks between blocks of items to reduce fatigue.
  • If two domains feel tied, re‑read items that felt uncertain.
  • Share the encoded link only with people you trust.
  • Keep notes on actions you try so you can link patterns to outcomes.
  • Repeat monthly to see whether changes persist across weeks.
