It characterizes the extent to which the distribution of a set of values deviates from a normal distribution. Skewness between -0.5 and 0.5 is symmetrical. Kurtosis measures whether data is heavily left-tailed or right-tailed.

Question 1: Calculate the probability density function of normal distribution using the following data. x = 3, μ = 4 and σ = 2. Solution: Given, variable, x = 3. Mean = 4 and. Standard deviation = 2. By the formula of the probability density of normal distribution, we can write; Hence, f(3,4,2) = 1.106.
