Also, the test statistic for both … WebIn this article, you will learn various formulas related to the angles and lines. The slope of a line is given as m = tan θ. If two points A (x 1, y 1) and B (x 2, y 2) lie on the line with x 1 ≠ x 2 then the slope of the line AB is given …
WebThus, elevated PTSS were associated with overall blunted profiles of cortisol stress reactivity in girls, but a larger quadratic slope in boys reflects a steeper cortisol increase and decline in boys. There was no relationship between trauma exposure (with or without PTSS) and cortisol reactivity profiles in HLM analyses.
