Normal variables, also known as normally distributed variables, are a type of statistical distribution that follows a bell-curve pattern. This means that most data points cluster around the average, with fewer data points at the extremes. Normal variables can be described using the mean, standard deviation, and variance. The mean represents the average value, while the standard deviation measures the amount of variation or dispersion from the mean. The variance is the square of the standard deviation.
