Probability Density Function (PDF): A PDF is another way to describe the distribution of a random variable, but it gives the probability density at each possible value rather than cumulative probabilities.

Mean: The mean is the average value of a set of numbers. In terms of probability distributions, it represents the center or expected value.

Standard Deviation: The standard deviation measures how spread out the values in a distribution are from their mean. It tells us about the variability or dispersion in the data.
