Mark Twain:
"There's lies, damn lies, and then there's statistics."
Think much has changed with regard to 'facts' and 'statistics'?

So, it is your conclusion that since 6 of 26 criteria improved with prayer, that prayer is effective. How then, do you account for the almost same number of criteria that were worse with prayer? Does that mean that God heard the prayers and decided to punish certain 'receivers' of prayer? Were they evil people and deserved the worst in spite of the prayers?
