The simplest case of a normal distribution is known as the standard normal distribution. This is a special case where Î¼=0 and Ï=1, and it is described by this probability density function : The factor in this expression ensures that the total area under the curve is equal to one.n probability theory, the normal (or Gaussian) distribution is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.
That gives considerable scope for speculation over what is meant by this phrase. The most common interpretation of 'break' in this context is 'to deviate from a straight line', as in the cricketing term 'off break', to unstraighten the leg by bending at the knee, by bowing or curtsying. 'Break a leg' also means 'make a strenuous effort'.
A 'Slipped Upper Femoral Epiphysis' (also called a 'SUFE') is a condition involving the hip joint. The hip joint works as a ball and socket.With a SUFE, the growth plate (called the epiphyseal plate) at the top of the thigh bone is weak and the ball (head of the femur) slips downward and backward.he exact cause of this condition is not known, but there may be a link between increased weight and puberty hormones. A 'SUFE' is not usually associated with an injury. The symptoms often develop slowly-over several months-and may seem like a pulled muscle in the hip, thigh or knee.
