Answer #1

When referring to the normal distribution, there is not just 'one' , there is a family of normal distributions.

In statistics, the normal distribution or the Gaussian distribution is a bell shaped distribution which is symmetric about its mean . The mean divides the distribution into two equal areas , that is , for a normal distribution,

Mean = median = mode

This implies the symmetricity of the distribution.

Hence, a normal distribution can never be skewed , whether positively or negatively. None of the distribution in the family of normal distributions is skewed.

The answer is :- false
