March 2023 Quarterly Update – Trust and Distrust Webinar
Topic: Press Release
Finding No: 9241
Join Roy Morgan CEO Michele Levine to discover:
- What are the most trusted and distrusted brands in Australia?
- How is Qantas faring since we revealed its dramatic fall from grace in our last update – is distrust in the national carrier reducing among Australians, or have they deteriorated further?
- Which bank is outperforming the other major banks and what is driving the improvement?
- What is behind the telecommunications industry becoming the most distrusted industry in the economy?
We will unpack these insights from surveys with more than 100,000 Australians.
Margin of Error
The margin of error to be allowed for in any estimate depends mainly on the number of interviews on which it is based. Margin of error gives indications of the likely range within which estimates would be 95% likely to fall, expressed as the number of percentage points above or below the actual estimate. Allowance for design effects (such as stratification and weighting) should be made as appropriate.
