Question

which do most psychologists and statisticians accept as real statistical significance?

○ p<.05

○ between 1.0 and -1.0

○ p<.5

○ between 0 and 1.0

Explanation:

In statistical hypothesis testing, the conventional threshold for "real" statistical significance, widely accepted by psychologists and statisticians, is a p - value less than 0.05 ($p <.05$). The option "Between 1.0 and - 1.0" is related to effect size or correlation coefficients, not statistical significance. A p - value less than 0.5 ($p <.5$) is too lenient and not the standard. The range "Between 0 and 1.0" is the general range of p - values (as they represent probabilities), but not the threshold for significance.

Answer:

A. $p <.05$
