A probability distribution is an idealized frequency distribution. A frequency distribution describes a specific sampleor dataset. It’s the number of times each possible value of a variable occurs in the dataset. The number of times a value occurs in a sample is determined by its probability of occurrence. … Visa mer A discrete probability distribution is a probability distribution of a categorical or discrete variable. Discrete probability distributions only … Visa mer A continuous probability distribution is the probability distribution of a continuous variable. A continuous variable can have any value between its lowest and highest values. Therefore, continuous probability distributions include … Visa mer Null distributions are an important tool in hypothesis testing. A null distribution is the probability distribution of a test statistic when the null hypothesis of the test is true. All hypothesis tests involve a test statistic.
