What is a repeated survey?
A repeated survey is a survey carried out more than once, mostly with regular frequency, for example monthly, quarterly, or annually. Most surveys in a statistical office are repeated. Samples in a repeated survey may be independent over time, or the sample design may deliberately involve a unit at several occasions.
Which survey gathers data over a period of time?
Longitudinal surveys are those surveys that help researchers to make an observation and collect data over an extended period of time. This survey data can be qualitative or quantitative in nature, and the survey creator does not interfere with the survey respondents.
How long should a survey period be?
How long should a survey be? It's best to keep surveys under 12 minutes – though 10 minutes is even better. Often, the longer the survey, the higher the dropout rate. Kantar has found that a survey that takes over 25 minutes loses more than three times as many respondents as one that is under five minutes.
