Compare survey waves when the respondent mix changes

Check respondent-group counts before interpreting a change in an overall survey percentage. Work through unchanged group rates with a shifting sample mix.

DESIGN THE ANSWER SPACE

PROMPT 01

Which invitation route brought you to this questionnaire?

Optional short open textUse a non-identifying route description to inspect cohort composition.
PROMPT 02

What recent experience are you using to answer the feedback question?

Optional short open textCheck whether waves refer to comparable experience rather than merely identical wording.
PROMPT 03

Does the stated time period match that experience?

Optional short open textFind period mismatch that can change which experience is reported.

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

Wave 1 has channel A 16 favourable of 20 and B 40 of 80. Wave 2 has A 64 of 80 and B 10 of 20.

02 / INVESTIGATE

Choose an action to test

Report both channel percentages and counts alongside each overall percentage; investigate invitation mix before claiming the service improved.

03 / FOLLOW UP

Check the experience again

For the next wave, retain wording, period and invitation rules where possible and compare counts plus within-channel percentages.

Read the answers carefully

Limits to preserve

Equal wording does not ensure comparable respondents. This synthetic channel mix is not a weighting recommendation or a significance test.

Comparison note: the overall share rises from 56% to 74% in the synthetic sample while both channel shares remain unchanged. Investigate recruitment mix before claiming an experience change.

From question to next step

Make the feedback useful.

01

Set the decision

Pilot with people reached through each planned invitation route before comparing successive waves.

02

Invite relevant voices

Report both channel percentages and counts alongside each overall percentage; investigate invitation mix before claiming the service improved.

03

Choose an action

For the next wave, retain wording, period and invitation rules where possible and compare counts plus within-channel percentages.

A useful starting point

Free-text pilot questions

Two feedback waves use the same question but different invitation channels. An overall percentage rises while each channel’s percentage stays the same. Review cohort definitions before interpreting the trend.

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

QUESTION 01

Which invitation route brought you to this questionnaire?

Use a non-identifying route description to inspect cohort composition.

QUESTION 02

What recent experience are you using to answer the feedback question?

Check whether waves refer to comparable experience rather than merely identical wording.

QUESTION 03

Does the stated time period match that experience?

Find period mismatch that can change which experience is reported.

QUESTION 04

Which part of this invitation differs from the one you saw previously, if any?

Probe invitation context without requiring someone to have answered an earlier wave.

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.

Before you send it

Check what your wording assumes.

BEFORE / LEADING

Why did satisfaction improve this month?

AFTER / CONTEXTUAL

What recent experience are you using to answer the feedback question?

The revision avoids assuming improvement and checks experience comparability.

Run a focused feedback cycle

Plan the invitation, review and follow-up.

When and whom to ask

Pilot with people reached through each planned invitation route before comparing successive waves.

Who reviews the finding

The reporting reviewer owns the comparison; the recruitment owner records invitation channels and eligibility.

What to check after a change

Check whether any later overall movement is accompanied by within-channel movement and stable collection context.

Handle responses carefully

Do not request contact identifiers merely to identify a channel. Avoid publishing tiny identifiable groups; use an organization-approved aggregation rule.

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.

% favourable, descriptive sample · synthetic values
Wave 1 overall
56.0
Wave 2 overall
74.0
Channel A, both waves
80.0
Channel B, both waves
50.0

Read units and denominators with the source table. These are invented example records.

Work through the rule

Wave 1 overall = (16+40)/(20+80)=56%. Wave 2 overall = (64+10)/(80+20)=74%. Channel A remains 80% and B 50%; the mix changes.

Comparison note: the overall share rises from 56% to 74% in the synthetic sample while both channel shares remain unchanged. Investigate recruitment mix before claiming an experience change.

Before you send it

Questions, answered.

Did the service necessarily improve?

No. These invented numbers show how a respondent-mix change can move the overall percentage with unchanged group shares.

Should I automatically weight the answers?

No. Weighting needs a justified target population and method; this worksheet supplies neither.

What belongs beside the overall trend?

Group counts, group shares, question wording, collection period and invitation context.

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.
