Detailed explanation-1: -For example, the test scores on a standardized test are discrete because there are only so many values that can be obtained on a test.
Detailed explanation-2: -There is no restriction to the type of values that can be taken by variables like temperature, height, weight and marks. Hence they would be examples of continuous variables.
Detailed explanation-3: -For example, the grade you receive in your school exam (A, B, C, D, or E) is an example of discrete data because your grade can only take on one of these 5 possible values and nothing else. Discrete data can be further sub-divided into three categories: binary, nominal and ordinal.
Detailed explanation-4: -Discrete: Countable items that can’t be logically subdivided, such as the number of errors (you can’t have half an error) or the number of calls to tech support are considered discrete. Discrete data that has only two values is a called discrete-binary data.
