Key Concepts

Normal Distribution

A normal distribution is a probability distribution that is symmetric about its mean, with data near the mean more frequent in occurrence than data far from the mean. Its bell-shaped curve is defined by two parameters: the mean, which indicates the center of the distribution, and the standard deviation, which measures the spread or dispersion of the data.

Z-score Transformation

The z-score transformation converts a normal random variable to a standard normal variable by subtracting the mean and dividing by the standard deviation. This standardization facilitates the use of standard tables and computational tools to determine probabilities and percentiles across different normal distributions.

Cumulative Distribution Function (CDF)

The cumulative distribution function of a random variable specifies the probability that the variable takes on a value less than or equal to a given number. In problems involving the normal distribution, the CDF is used to determine the proportion of data within a specified range or beyond a certain threshold.
