1. Normal PDF (Probability Density Function):
- The normal PDF is a probability distribution function that describes the likelihood of a continuous random variable taking on a certain value.
- It is characterized by a bell-shaped curve, with the majority of the data clustered around the mean value.
- The normal distribution is symmetrical, with the mean, median, and mode all being equal.
- The normal PDF is not limited to a specific range of values, and it can take on any real value.
2. Binomial PDF (Probability Density Function):
- The binomial distribution is a discrete probability distribution that describes the likelihood of a specific number of successes in a fixed number of trials.
- It is used when there are only two possible outcomes (success or failure) for each trial.
- The binomial PDF is characterized by a series of spikes or bars representing the likelihood of a certain number of successes.
- The binomial distribution is not symmetrical, and the mean, median, and mode may not necessarily be equal.
- The binomial distribution is limited to a specific range of values based on the number of trials and the probability of success.
In summary, the normal PDF is used for continuous random variables with a bell-shaped curve, while the binomial PDF is used for discrete random variables with two possible outcomes.
