The above headline appears in the Herald today based on a self-selecting survey with around 3 000 ‘parents and carers’ taking part.

There are 1,452,240 pupils enrolled in Scotland’s schools so there are around 3 million biological parents in Scotland. There are are, of course, unknown numbers of grandparents and carers actively engaged in the schooling of their grandchildren.

So, roughly speaking, 1 in a thousand or more, at best 0.1%, of all parents or carers in Scotland, took part in this unscientific, self-selecting, thus statistically insignificant and unreliable, survey?

At the very least, given the constitutional issues dominating Scottish politics, any professionally conducted opinion poll would have ensured that around 50% of the sample were SNP voters.
