For example, the concentration of glucose in the blood is a continuous quantity. Even if the instrument you are using rounds off values to whole numbers, these quantities are still continuous, ie, not countable.
Is sugar level a continuous variable?
Height of a person, weight, age, arm length, blood pressure, temperature, glucose level are some of the examples for continuous variable. Here the obtained measurements can take any value in a given range. Discrete variable (discontinuous variable) can take only specified number of values in a given range.
What level of measurement is blood sugar level?
A blood sugar level less than 140 mg/dL (7.8 mmol/L) is normal. A reading of more than 200 mg/dL (11.1 mmol/L) after two hours indicates diabetes. A reading between 140 and 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) indicates prediabetes.
What type of variable is blood sugar?
A numerical or continuous variable (attribute) is one that may take on any value within a finite or infinite interval (e.g., height, weight, temperature, blood glucose, …).
How do you know if something is discrete or continuous?
A discrete function is a function with distinct and separate values. A continuous function, on the other hand, is a function that can take on any number within a certain interval. Discrete functions have scatter plots as graphs and continuous functions have lines or curves as graphs.
What are examples of discrete data?
Discrete data is information that we collect that can be counted and that only has a certain number of values. Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit.
Is BMI continuous?
In our set above, blood pressure measurements and Body Mass Index (or BMI) would be clearly continuous. These are true measurements, limited only by our desire or ability to measure more precisely.
What is normal blood sugar by age?
Normal blood glucose levels for adults, without diabetes, is 90 to 110 mg/dL. Learn the symptoms of high and low blood sugar here.

Normal blood sugar levels for adolescents.
| Normal blood sugar levels for adolescents | |
|---|---|
| Age 6-12 | mg/dL |
| Fasting | 80-180 |
| Before meal | 90-180 |
| 1-2 hours after eating | Up to 140 |
Is 5.5 blood sugar normal?
Normal: 3.9 to 5.4 mmols/l (70 to 99 mg/dl) Prediabetes or Impaired Glucose Tolerance: 5.5 to 6.9 mmol/l (100 to 125 mg/dl) Diagnosis of diabetes: 7.0 mmol/l (126 mg/dl) or above.
Is 200 blood sugar normal after eating?
Results are interpreted as follows: Less than 140 mg/dL (7.8 mmol/L) is normal. 140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) is diagnosed as prediabetes. 200 mg/dL (11.1 mmol/L) or higher after two hours suggests diabetes.

What is an example of continuous data?
Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data. Some continuous data will change over time, the weight of a baby in its first year or the temperature in a room throughout the day.
When do we use discrete?
Discrete Definition and Examples
Discrete means separate, and discreet means “with caution” or “intentionally unobtrusive.” If it is still a little confusing, try to make a mnemonic. For example, the two E’s of discrete are separated by a T, so discrete means separate.
What is not continuous data?
A discrete variable is a kind of statistics variable that can only take on discrete specific values. The variable is not continuous, which means there are infinitely many values between the maximum and minimum that just cannot be attained, no matter what.
Is age continuous or discrete?
Age is, technically, continuous and ratio. A person’s age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough.
Is length discrete or continuous?
Continuous random variables are often measurements, such as weight or length. We view measurements as continuous even though the limitations of a ruler or a scale give discrete measurements.
Is gender discrete or continuous?
Variable Reference Table : Few Examples
| Variable | Variable Type | Variable Scale |
|---|---|---|
| Length | Continuous | Ratio |
| Product ID in Numbers | Discrete | Nominal |
| Gender | Discrete | Categorical |
| Gender as Binary 1/0 Coding | Discrete | Categorical |
Is yes or no discrete or continuous?
Discrete Data
Binary Data: A binary data only takes on two possible values. For example, lamp is on or lamp is off, answer is true or false, 0 or 1, yes or no etc. If you collect the data about the number of reports that have an error that would be an example of binary data.
Are grades categorical or continuous?
They are not continuous, like quantitative data, but they can be ordered. Most known example are letter grades for tests. Use: Quantitative data can be used with all three centre measures (mean, median and mode) and all spread measures.
Is 5.7 blood sugar normal?
In general: A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L ) is considered prediabetes. This result is sometimes called impaired fasting glucose.
Is 170 sugar level normal?
The goal for managing diabetes is to achieve glucose values as close to this as possible, but the recommended range is 80-130 mg/dl. There is no specific value used to define hyperglycemia in all individuals. In general, a glucose level above 160-180 mg/dl is considered hyperglycemia.
Is fasting blood sugar 119 high?
Low blood sugar or hypoglycemia is when blood levels drop below 70 mg/dL in diabetics or around 55 mg/dL (3 mmol/L) in healthy people. High blood sugar or hyperglycemia is when your blood glucose levels are too high, above 126 mg/dL or 7 mmol/L. The normal fasting blood sugar range in healthy people is 70 – 125 mg/dL.
Is 8.9 blood sugar normal?
A normal pre-prandial (before meal) blood glucose level will be between 4 and 7 mmol/l. After eating (post-prandial) levels should be below 9 mmol/l when tested 2 hours after a meal. When going to bed for the night, levels should be no more than 8 mmol/l.
Is 4.8 blood sugar level good?
Blood sugar levels of higher than 4.7 to 4.8 are a potential early signal of your body’s impaired ability to handle ingested sugar and can be associated with a higher likelihood of progressing with time, to fulfill WHO definition of diabetes.
Can I drink water before fasting blood sugar test?
For a fasting blood glucose test, you can’t eat or drink anything but water for eight hours before your test. You may want to schedule a fasting glucose test first thing in the morning so you don’t have to fast during the day. You may eat and drink before a random glucose test.
What are discrete data?
Discrete data is a count that involves integers — only a limited number of values is possible. This type of data cannot be subdivided into different parts. Discrete data includes discrete variables that are finite, numeric, countable, and non-negative integers.
What are examples of discrete and continuous variables?
Difference between Discrete and Continuous Variable
| Discrete Variable | Continuous Variable |
|---|---|
| Examples: Number of planets around the Sun Number of students in a class | Examples: Number of stars in the space Height or weight of the students in a particular class |
Are numbers discrete or continuous?
A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects. Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time.
What is discrete or discreet?
Discrete means “separate,” while discreet means “unobtrusive.” Both words have the same etymology coming from the Latin discretus which means “to keep separate” or “to discern.” An easy trick to tell them apart is to remember is that the “e’s” are separated by the “t” in “discrete.”
Is income discrete or continuous?
Income is a continuous variable. Household size and number of computers are discrete variables.
What does Discreate mean?
Definition of discreate
: to reduce to chaos : annihilate.
Is Test score continuous or discrete?
As a result, the test-scores are discrete data. Although most discrete data, refers to things we can count easily, it does not have to be numeric. Non-numeric categories could be described as discrete data. For example, the list of colors offered by a car manufacturer, may be extensive, but is limited.
Is heart rate continuous or discrete?
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.
