Even when the father was an irregular attender and the mother non-practising, a full 25% of their children became regular attenders, while if a mother was a regular attender and the father irregular, only three per cent of the children became regular attenders.

Seems to imply that a devout mother ought to pretend to be nonpracticing if the father is irregular; to a tune of 3% vs 25%...that doesn't seem very likely.

In short, if a father does not attend church, it won't matter how dedicated the mother is in her observance, only one child in 50 will become a regular attender. But if a father is even somewhat observant, then regardless of the mother's practice, at least one child in three will become a regular church-goer.

OK, so this contradicts the paragraph that was written before it. Seems like this is more likely, so I presume the other was in error.
