A continuous variable is one that in theory could take any value in an interval. Examples of continuous variables are body mass, height, blood pressure and cholesterol.
Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable.
Discrete or categorical variables are those which can only assume certain fixed or integer values. Age, heart rate, systolic blood pressure, and cardiac output are examples of continuous variables.
Blood pressure is a quantitative variable, as it is measured numerically.
On the other hand, during diastole, the blood volume in the finger is decreased, as a result, cuff pressure is lowered and again the overall blood volume remains constant. As blood volume and, thus, the light signal is held constant over time, intra-arterial pressure is equal to the cuff pressure.
Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general "continuous " category.
The problem is in the measurement. Practicality dictates that we have to limit measurements to a certain accuracy, we cannot measure everything to 10 or more decimal places! For this reason, continuous data is sorted into groups or classes with well defined boundaries.
Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general "continuous " category.
Categorical variable: a variable can only have one value from a limited range of values. For example, blood group and gender are forms of categorical data. An example might be heart rate or blood pressure.
2) Continuous Variables: These are sometimes called quantitative or measurement variables, they can take on any value within a range of plausible values. For example, total serum cholesterol level, height, weight and systolic blood pressure are examples of continuous variables.
24-hour ambulatory blood pressure monitoring is a method to measure blood pressure on a continuous basis. Your BP is measured even as you sleep. The ongoing data helps your doctor get a more accurate picture of your blood pressure numbers.

Variables such as heart rate, platelet count and respiration rate are in fact discrete yet are considered continuous because of large number of possible values. Only those variables which can take a small number of values, say, less than 10, are generally considered discrete.
Explanation: Discrete data is data where it has to be from a certain set of values e.g a shoe size can only be a certain value. The height is continuous as the height could take multiple values e.g from 10m all the way up 18.95m.
Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general "continuous " category.
Blood pressure is recorded as two numbers and written as a ratio: the top number, called the systolic pressure, is the pressure as the heart beats. The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats.
Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general "continuous " category.
Categorical variable: a variable can only have one value from a limited range of values. For example, blood group and gender are forms of categorical data. The values belong to some sort of category, on the basis of a qualitative property. An example might be heart rate or blood pressure.
At each sitting, measure your blood pressure three times, but discard the first reading as it tends to be inaccurate. Write down the average of the second and third reading. Bringing your latest readings to an appointment helps give your doctor a good idea of what your blood pressure is outside of the office.
Diastolic pressure (the second, lower number) reflects the pressure in the arteries when the heart rests between beats. Over eight years, more than 44,000 people in the study had a heart attack or stroke.
A discrete variable is one that cannot take on all values within the limits of the variable. The variable cannot have the value 1.7. A variable such as a person's height can take on any value. Variables that can take on any value and therefore are not discrete are called continuous.
What is hypotension? Hypotension is abnormally low blood pressure (lower than 90/60 mm Hg). If your blood pressure gets too low, it can cause dizziness, fainting or death. Low blood pressure is not a condition that is usually treated except if it occurs in the elderly or occurs suddenly.
The force of circulating blood on the walls of the arteries. Blood pressure is taken using two measurements: systolic (measured when the heart beats, when blood pressure is at its highest) and diastolic (measured between heart beats, when blood pressure is at its lowest).
Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general "continuous " category.
However in the movie it's portrayed as a punch. Hermione punched Draco Malfoy in the third book/movie as they where heading down to Hagrid's hut to try and comfort him as that day Buckbeak would be executed.
Chapter: Twelve - The Polyjuice Potion. Brief summary of scene: Hermione spends time in the hospital wing, as half a cat.
