A unique code given to a specific respondent so only they can open and complete a survey, commonly used for controlled panels or invite-only research.
A survey submission collected without recording any information that could identify who submitted it.
Application Programming Interface - a way for other software to read your surveys and responses programmatically instead of through the web panel.
Routing respondents to different questions or pages based on how they answered an earlier question. See also Skip logic.
A question with a fixed set of answer choices, such as single choice, multiple choice, or a rating scale - as opposed to an open-ended text question.
The share of respondents who started a survey and went on to finish it, usually expressed as completed responses divided by delivered invitations.
Learn more →The range a survey result is likely to fall within across the true population, calculated as the result plus or minus the margin of error.
How sure you want to be that your confidence interval actually contains the true value - typically expressed as 90%, 95%, or 99%.
Customer Satisfaction Score - a metric measuring satisfaction with a specific interaction, usually on a 5-point scale from very dissatisfied to very satisfied.
Learn more →In an NPS question, a respondent who scores 0-6, indicating they are unlikely to recommend and may actively discourage others.
Learn more →Respondents who start a survey but abandon it before reaching the end, often concentrated at a specific question that's too long, sensitive, or confusing.
A statistical adjustment that reduces the required sample size when your population is small enough that sampling a meaningful fraction of it improves precision.
A rating scale (commonly 5 or 7 points) that lets respondents indicate their level of agreement, satisfaction, or frequency, from one extreme to the other.
How much a survey result might differ from the true value across your whole population, expressed as a plus-or-minus percentage.
Learn more →A grid-style question that asks respondents to rate several items (rows) against the same set of answer options (columns) in one compact table.
Net Promoter Score - a loyalty metric from 0-10 "how likely are you to recommend us" question, calculated as the percentage of Promoters minus the percentage of Detractors.
Learn more →A question that lets respondents answer in their own words rather than picking from fixed options, such as a short-text or long-text field.
A pre-recruited group of people who agree to take surveys on an ongoing basis, often used for longitudinal or repeated research.
In an NPS question, a respondent who scores 7-8 - satisfied but not enthusiastic enough to actively promote you.
Learn more →Automatically inserting a respondent's earlier answer into the text of a later question, so a survey can reference their own previous input.
The entire group you want to draw conclusions about, whether or not you actually survey every member of it - for example, "all customers" or "all employees."
In an NPS question, a respondent who scores 9-10, indicating strong loyalty and a high likelihood of recommending you to others.
Learn more →A cap on how many responses are collected from a particular segment of respondents, used to keep a sample balanced across groups.
Presenting questions or answer options in a different order to each respondent, to reduce bias caused by position (such as always picking the first option).
A question that asks respondents to order a list of items by preference, rather than rating each one independently.
A prepaid unit that a pay-per-response survey consumes once per completed response, instead of drawing against a subscription's monthly response limit.
How many of the people you invited actually took part in your survey, most commonly measured as completion rate.
Learn more →The subset of a population that actually responds to your survey, used to estimate what the whole population thinks.
The number of respondents needed for a survey's results to reliably represent the target population, given a chosen confidence level and margin of error.
Learn more →A rule that ends a survey early, or skips later questions, based on how a respondent answered an earlier one.
A question answered by dragging a handle along a numeric range, rather than picking from discrete options.
The share of people who received a survey invitation and actually opened and began the survey, regardless of whether they finished it.
Learn more →A measure of how likely it is that a result reflects a real effect rather than random chance, typically based on sample size and the size of the observed difference.
Any rule that changes what a respondent sees next based on their previous answers - includes skip logic, branching, and piping.
The page or message shown to a respondent immediately after they submit a survey, which can be customized with a message or a redirect to another URL.
An automated HTTP request sent to a URL you register, fired the moment an event happens - such as a respondent completing a survey - so external systems can react immediately.
An average that accounts for how many responses fall at each point on a scale, rather than just counting how many chose the top options - used alongside CSAT to show the full distribution.
Learn more →A statistical value corresponding to a chosen confidence level (for example 1.96 for 95% confidence), used in the formulas for margin of error and sample size.
