BUT SOME WERE MORE ACCURATE THAN OTHERS
THE POLLSTERS UNDER ACCUSATION
WHAT WENT RIGHT WHY IT WENT RIGHT
IPSOS correctly described the scenario
• The high level of abstention (26,5%)
• The dramatic growth of M5S
• The victory of the centre-left at the
Chamber of Deputies
• The hung Senate
• All the other parties’ results
Because
• A mixed sampling method was used
• Sample sizes were large enough
• We had been polling continuously –
weekly, even daily – for a long time
• We had a wealth of data
• We had lots of analyses on targets,
geographical areas, voters switch
dynamics
