Webb14 jan. 2015 · Lets start with a simple example of Bernoulli distribution: f ( x) = { p if x = 1, 1 − p if x = 0. Since the values are discrete there is no "curve" but only two points, however the idea is similar: if you want to know total probability (area under the curve) you have to sum up probabilities of both possible outcomes: p + ( 1 − p) = 1 WebbProbability is the chance that the variable has a specific value, whereas the probability density is the chance that the variable will be near a specific value, meaning probability over a range. So to obtain the probability you need to compute the integral of the probability density function over a given interval.
WebbThe Normal Probability Distribution is very common in the field of statistics. Whenever you measure things like people's height, weight, salary, opinions or votes, the graph of the results is very often a normal curve. The Normal Distribution A random variable X whose distribution has the shape of a normal curve is called a normal random variable. WebbIn a normal distribution, only 2 parameters are needed, namely μ and σ 2. Area Under the Normal Curve using Integration . The probability of a continuous normal variable X found …
