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.
In Chapter 1 we saw that the n th triangular number T n is given by the formula T n = 1+2+3+ Â·Â·Â· + n = n (n +1)2: The ï¬rst few triangular numbers are 1, 3, 6, and 10.
