Frequently asked questions about opinion polls
- What does the change in percentage points mean?
The change in percentage points indicates how much support for a party has increased or decreased compared to the previous measurement from the same institute. - How often are opinion polls conducted?
Opinion institutes typically publish new measurements every month, but some institutes release reports more frequently. - What is the parliamentary threshold?
The parliamentary threshold is 4 %. A party needs at least 4 % of the votes to gain seats in the parliament. - How should the margin of error be interpreted?
The margin of error indicates the statistical uncertainty. Small differences between parties may fall within the margin of error and are therefore not always statistically significant. - What is the difference between voter support and seats?
