In statistics we tend use the 'hat' notation to imply a statistic. We designate P to represent the proportion in the population. Because P is unknown and unknowable we use Phat to designate the proportion in the sample. Suppose 30 out of 100 people in my sample support Trump. P = unknown and unknowable.
In scientific studies, this is known as the p-value.. If it is unlikely enough that the difference in outcomes occurred by chance alone, the difference is pronounced statistically significant.. Mathematical probabilities like p-values range from 0 (no chance) to 1 (absolute certainty).
