WHAT TO READ · WHAT TO TEST

Observation

Synthetic counts on a low-to-high five-point satisfaction scale are 1,1,2,3,5; three separate cases are not applicable.

Interpretation boundary

A top-two-box share depends on the chosen labels and denominator. It is not NPS, a validated scale or evidence that numeric codes have equal distances.

Next experiment

Use the top labels 4 and 5 as eight favourable ratings among 12 valid ratings; report the three not-applicable cases separately.

Illustrative scenario. These are not real response counts or findings.

A useful starting point

Free-text pilot questions

A worksheet combines five satisfaction categories with three not-applicable records. Verify which labels are favourable before counting and pilot the meaning of those labels.

If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

QUESTION 01

What does the lowest rating label mean to you?

Check that the low endpoint refers to the intended negative experience.

QUESTION 02

What does the highest rating label mean to you?

Verify the high endpoint’s direction rather than relying on numeric code alone.

QUESTION 03

Which two labels would describe a favourable experience, and why?

Test how people interpret the selected favourable categories.

QUESTION 04

What would you choose if you had not experienced the service?

Keep non-exposure separate from neutral experience.

Before you send it

Check what your wording assumes.

BEFORE / LEADING

How satisfied are you? Choose any number.

AFTER / CONTEXTUAL

What does the highest rating label mean to you?

The pilot tests label meaning before treating a code as a favourable attitude.

Make questions optional where appropriate. If you add a rating scale, label its endpoints, keep one idea per question, and retain a follow-up for reasons. These examples are not a validated measurement instrument.

From question to next step

Make the feedback useful.

01

Set the decision

Pilot scale wording before fielding the main survey with people who have and have not experienced the service.

02

Invite relevant voices

Use the top labels 4 and 5 as eight favourable ratings among 12 valid ratings; report the three not-applicable cases separately.

03

Choose an action

After revising ambiguous labels, pilot both endpoints again; do not directly compare scores collected under different labels.

A worked interpretation example

From a comment to a practical next step.

Illustrative scenario. These are not customer results.

01 / OBSERVE

Keep the finding specific

Synthetic counts on a low-to-high five-point satisfaction scale are 1,1,2,3,5; three separate cases are not applicable.

02 / INVESTIGATE

Choose an action to test

Use the top labels 4 and 5 as eight favourable ratings among 12 valid ratings; report the three not-applicable cases separately.

03 / FOLLOW UP

Check the experience again

After revising ambiguous labels, pilot both endpoints again; do not directly compare scores collected under different labels.

Read the answers carefully

Limits to preserve

A top-two-box share depends on the chosen labels and denominator. It is not NPS, a validated scale or evidence that numeric codes have equal distances.

Score note: eight of 12 valid ratings select the two stated favourable labels, approximately 66.7%; three not-applicable cases remain separate.

Run a focused feedback cycle

Plan the invitation, review and follow-up.

When and whom to ask

Pilot scale wording before fielding the main survey with people who have and have not experienced the service.

Who reviews the finding

The questionnaire owner approves endpoint labels; the analyst retains the valid-answer rule.

What to check after a change

Review changed label interpretation before deciding whether later numeric summaries are comparable.

Handle responses carefully

Pilot questions are free text. This worksheet’s scale counts are manually supplied examples, not a claim about native rating-field or scoring availability.

A worked measurement study

Inspect the data. Trace the decision.

Every record here is synthetic. Use the rule to review your own evidence before taking action.

66.67 % top-two-box

The written example remains below if JavaScript is unavailable. A calculation does not validate a sample, instrument or forecast.

Work through the rule

Valid ratings = 1+1+2+3+5=12. Top two = 3+5=8. Top-two-box = 8÷12×100≈66.7%. Three not-applicable cases are disclosed outside the rating denominator.

Score note: eight of 12 valid ratings select the two stated favourable labels, approximately 66.7%; three not-applicable cases remain separate.

Keep evidence and inference separate

Observed

Category labels and counts

Supports a labelled eight-of-12 share.

Unknown

Comparability with another scale

Do not equate top-two-box with NPS or an unlabeled average.

Preserve the rule when comparing later waves.

Before you send it

Questions, answered.

Why not divide by all 15 records?

This worked rule measures favourable ratings among valid ratings; not applicable is disclosed separately. State a different denominator if you choose one.

Can the top two mean unfavourable?

Yes, if the scale direction is reversed. Read labels before mapping codes.

Is this an NPS calculation?

No. This is a category-share example on a specified satisfaction scale.

Can I load this example automatically?

No. Copy or download the free-text pilot questions and adapt them in your draft. The registration link does not import them. The calculation worksheet is a separate manual example; verify supported fields and features in your account.
