51. Weighting data
Two kinds of statistics:

Descriptive statistics, methods of organizing and summarizing information about a population (ie. election canvass).

Inferential statistics measures the reliability of conclusions about a 'population' using a 'sample' of the population, a subset of the data (ie. exit poll).

If you sample 750 women and 250 men, you need to weigh their opinions in relation to the true population proportion.

The exit polls were weighted, perhaps incorrectly. Hence, the need to "adjust" --- or so goes the hindsight excuse being offered.

'Those who knows ain't talking.'

We might be better served by analyzing the election canvasses. No sampling errors there!!
