Detailed explanation-1: -true. a discrete variable is one that can take on an integer value only and is a finite number. the number of people standing in a room is a discrete variable.
Detailed explanation-2: -Number of patients in a hospital are discrete variable.
Detailed explanation-3: -For example, the number of people with a certain illness is a discrete quantity, ie, countable. The other type of data is continuous data, which is the measure of a quantity such as length, volume, or time, which can occur at any value. For example, the concentration of glucose in the blood is a continuous quantity.
Detailed explanation-4: -The word discrete means countable. For example, the number of students in a class is countable, or discrete. The value could be 2, 24, 34, or 135 students, but it cannot be or 12.23 students.
Detailed explanation-5: -As opposed to a continuous variable, a discrete variable can assume only a finite number of real values within a given interval. An example of a discrete variable would be the score given by a judge to a gymnast in competition: the range is 0 to 10 and the score is always given to one decimal (e.g. a score of 8.5).
