Trend study

from Wikipedia, the free encyclopedia

A trend study is a repeat survey , sometimes also called a replicative survey . They are part of the longitudinal studies .

In contrast to panel studies , the same people are not always interviewed here, but instead samples are repeatedly drawn from the same population .

By repeating the survey, each cross-sectional survey can be converted into a trend study. Trend studies are therefore exact "replicas" of previously carried out studies. The big advantage of trend studies is economic: They are much cheaper than panel studies.

Problems

  1. No analysis of so-called net changes (individual changes) possible
  2. Shift in meaning
  3. Structural change in the population
