It is a feature of a member of a given sample or population, which is unique, and can differ in quantity or quantity from another member of the same sample or population. We also made an important distinction between categorical variables, whose values are groups or categories (and an individual can be placed into one of them), and quantitative variables, which have numerical values for which arithmetic operations make sense. A student who has not studied for the test decides to answer all the questions randomly by guessing the answer to each question. Essentially, we will have a continuous random variable whenever the quantity we wish to study or model can assume every value along some interval of real numbers.

Explanation: A continuous random variable can take any possible value between two points whereas a discrete random variable can only take discrete values. The total area under the curve of the distribution is 1. See Answer. A variable that can take on only one of two values. The variable has a fixed value and does not vary. Variables either are the primary quantities of The probability distribution of a continuous random variable is represented by a probability density curve. Categorical variables contain a finite number of categories or distinct groups. The probability that the continuous random variable takes on a value in between c c and d d is the area under the curve of the distribution in between x = c x = c and x = d x = d. Continuous variables can assume all values between two given values of the variable. The probability that X gets a value in any interval of interest is the area above this interval and below the density curve.
