Fathers who are secondary to a female caregiver were more engaged as thinkers and planners. But men raising a child without a female partner were found to have the same level of emotional response as a mother and the same thinking and planning response as the secondary father.
In statistics and probability theory, triangular distribution is a continuous probability distribution. The probability density function of a triangular distribution is shaped like a simple geometric shape, triangle. The triangular distribution is a good model for skewed distributions. It has a definite lower and upper limit, which is helpful to avoid unwanted extreme values.
When the second moment for a triangular distribution is calculated, it is found to have the value a 2 /24, where a is the overall width of the distribution. The square root of this quantity is taken to find the standard uncertainty which results in the value a /â24 or equivalently a /2 â6.
