Final answer:
The normal distribution is a continuous probability distribution that is used in almost all disciplines. It has a bell-shaped graph and is characterized by its mean and standard deviation.
Step-by-step explanation:
The normal distribution is a continuous probability distribution. It is the most important of all the probability distributions and is used in almost all disciplines. The graph of the normal distribution is bell-shaped, with a mean (μ) and a standard deviation (σ). The standard normal distribution is a special case of the normal distribution with a mean of zero and a standard deviation of one
