Is blood glucose a ratio variable?

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.). There are two types of numerical variables, interval and ratio.

What type of variable is blood sugar level?

Height of a person, weight, age, arm length, blood pressure, temperature, glucose level are some of the examples for continuous variable.

What is the ratio of blood sugar?

For the majority of healthy individuals, normal blood sugar levels are as follows: Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting. Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating.

What is ratio variable research?

A ratio variable, has all the properties of an interval variable, and also has a clear definition of 0.0. Examples of ratio variables include: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight, length, temperature in Kelvin (0.0 Kelvin really does mean “no heat”), survival time.

Is BMI a ratio variable?

Some laboratory tests are good examples of ratio level data. This interval-level BMI data can be collapsed into ordinal categories such as obese, overweight, and underweight, or it can be reduced to nominal-level categories such as overweight and not overweight.

Is sugar a dependent variable?

Sugar consumption might be a dependent variable in a study in which you compare a group of children who received specific nutritional classes to a control group of children who did not receive such classes, and you subsequently measure the amount of sugar consumed.

What is a low blood sugar level?

Blood sugar below 70 mg/dL is considered low. If you think you have low blood sugar, check it. If you aren’t able to check it, go ahead and treat it. Untreated low blood sugar can be dangerous, so it’s important to know what to do about it and to treat it immediately.

WHO recommended blood sugar levels?

Rationale: The expected values for normal fasting blood glucose concentration are between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L). When fasting blood glucose is between 100 to 125 mg/dL (5.6 to 6.9 mmol/L) changes in lifestyle and monitoring glycemia are recommended.

What are the examples of ratio?

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3).

What is ratio data examples?

Examples of Ratio Data Kelvin Scale: One most noted example of Ratio Data is the temperature on a Kelvin scale. The O degrees in a Kelvin scale represent the total absence of thermal energy. Height: Height or length is measured in meters, inches, or feet. Height cannot have a negative value.

Is BMI an example of ratio data?

Some laboratory tests are good examples of ratio level data. A person who weighs 100 kilos is twice as heavy as a person who weighs 50 kilos, and a measure of zero kilos is meaningful. For example, Body Mass Index, or BMI, is often measured at the interval level and is given a score such as 23.4.

What are the four levels of measurement in research and statistics?

Here’s more of the four levels of measurement in research and statistics: Nominal, Ordinal, Interval, Ratio. Nominal Scale, also called the categorical variable scale, is defined as a scale used for labeling variables into distinct classifications and doesn’t involve a quantitative value or order.

What are some examples of ratio level data?

Examples of ratio level data include distance and area (e.g., acreage). The scales are similar in so far as units of measurement are arbitrary (Celsius versus Fahrenheit, Gregorian versus Islamic calendar, English versus metric units). The scales differ in that the zero point is arbitrary on interval scales,…

How many levels of variables can be applied in a research study?

You can apply just two levels (e.g. the new medication and the placebo) in order to find out if the independent variable has an effect at all. You can also apply multiple levels (e.g. three different doses of the new medication) to find out how the independent variable affects the dependent variable. Variables in other types of research

Which measurement scale can be used to label variables?

The simplest measurement scale we can use to label variables is a nominal scale. Nominal scale: A scale used to label variables that have no quantitative values. Some examples of variables that can be measured on a nominal scale include: Gender: Male, female; Eye color: Blue, green, brown; Hair color: Blonde, black, brown, grey, other
