So, 68% of the time, the value of the distribution will be in the range as below, The mean return for the weight will be 65 kgs.read more, then 68% of it lies within 1 standard deviation, 95% lies within 2 standard deviations, and 99% lies with 3 standard deviations. This distribution has two key parameters: the mean (µ) and the standard deviation (σ) which plays a key role in assets return calculation and in risk management strategy. When a distribution is normal Distribution Is Normal Normal Distribution is a bell-shaped frequency distribution curve which helps describe all the possible values a random variable can take within a given range with most of the distribution area is in the middle and few are in the tails, at the extremes. It is required to calculate the Z-score for an observation. In other words, it is the distance of a data point from the population mean that is expressed as a multiple of the standard deviation. It is done with the help of the z-score formula Z-score Formula The Z-score of raw data refers to the score generated by measuring how many standard deviations above or below the population mean the data, which helps test the hypothesis under consideration. So it is essential to standardize the observations to be able to compare that. In most of the cases, the observations do not reveal much in its raw form. The formula for the calculation can be represented as It has two tails one is known as the right tail and the other one is known as the left tail. positive values and the negative values of the distribution can be divided into equal halves and therefore, mean, median and mode will be equal.

Normal distribution is a distribution that is symmetric i.e.
