Detailed explanation-1: -So, for height, according to the above mentioned conditions, if we take a=0 and b=∞, then the required interval will be [0, ∞) and we know that height can take all the values in this interval. Hence, height is a continuous variable.
Detailed explanation-2: -A variable is said to be continuous if it can assume an infinite number of real values within a given interval. For instance, consider the height of a student. The height can’t take any values. It can’t be negative and it can’t be higher than three metres.
Detailed explanation-3: -Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.
Detailed explanation-4: -Therefore, at a macroscopic level, the mass, temperature, energy, speed, length, and so on are all examples of continuous variables.
Detailed explanation-5: -Examples of continuous data include weight, height, length, time, and temperature.
