ONE CLEAR WORKING QUESTION

Ten responses, not five equally weighted bins

The mean uses every response count; a bin with zero responses contributes nothing.

TEN RESPONSES ON A FIVE-POINT SCALE3.60 / 5

Counts of 2, 1, 0, 3 and 4 give 36 score-points across 10 responses. Higher means easier only because that direction is declared.

01

Weight every response, not every occupied bin

Use counts from one question with one five- or seven-point scale. Enter a whole response count, including zero, for every score. Multiply each score by its count, add those score-points and divide by the total responses. Keep the question, direction, period and channel consistent.

02

Keep one question and one scale together

Counts of 2, 1, 0, 3 and 4 produce 36 score-points across 10 responses: a mean of 3.60 on a five-point scale. Higher scores mean easier only when that direction was used in the original question.

03

Compare effort with separate outcome measures

Use the retention rate calculator for an observed matched customer cohort and the retail conversion rate calculator for matched store visits and transactions. A survey mean does not prove either outcome changed.

04

Read direction before interpreting a score

Read the response counts alongside the mean and scale direction. This tool does not turn a survey mean into a success percentage or a universal benchmark. It also cannot establish why effort changed or whether loyalty and retention improved.

Questions, answered.

Which way should the scale run?

Use the direction from the original question. Higher-easier and higher-harder change endpoint labels and interpretation, not the raw numerical mean or frequency counts.

Can I combine five- and seven-point questions?

No. Keep one question, response scale and direction together. Changing scale clears the current counts and result so hidden bins cannot contaminate a new calculation.

Is a particular score universally good?

No universal benchmark or success percentage is supplied. Interpret the declared question, scale, direction, sample and period; the mean does not establish loyalty, retention or causality.
