It is always numerical in nature. and measures of time, height, distance, volume, mass (and so on) are all types of quantitative data. Examples include time, height and weight. Legal. In contrast to discrete random variable, a random variable will be called continuous if it can take an infinite number of values between the possible values for the random variable. More accurately, they should be described as, In general, continuous data is best represented using. Discrete data is based on counts where only a finite number of values is possible. The value can be represented in decimal, but . lemons, melons, plants, cars, airplanes you choose!) The radioactive material is changing every instant.
