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.
For example: a triangular distribution with lower value of 15, higher value of 80, and mode of 25 will be skewed to the left. Above graph shows the pdf of a triangle distribution with m = 2, n = 7 and t = 4. Triangular distribution is defined by three points:1) Minimum point 2) Maximum point 3) Peak point.
