Is blood pressure quantitative discrete?

Is blood pressure an example of continuous or discrete data? Blood pressure is an example of continuous data.

Is blood pressure quantitative or qualitative?

The primary outcome of the hypertension study is blood pressure. Is blood pressure a qualitative or quantitative variable? Blood pressure is a quantitative variable, as it is measured numerically.

Is blood pressure quantitative data?

Quantitative data: measured on some numerical scale. An example might be heart rate or blood pressure.

Is blood pressure quantitative continuous?

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.

Is pressure a discrete variable?

1 Answer. Blood pressure itself is continuous, but the measurement of it would appear to be discrete because of the limit on accuracy which can be recorded.

Qualitative and Quantitative

What kind of variable is blood pressure?

Examples of continuous variables are body mass, height, blood pressure and cholesterol.

Is systolic blood pressure a discrete or continuous variable?

– Is systolic blood pressure discrete or continuous? Theoretically, the systolic blood pressure of an individual is a continuous variable since it can take on any value between 0 and 300 mmHg.

What level of measurement is used for blood pressure?

Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value.

Is heart rate discrete or continuous?

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.

Is blood pressure a ratio variable?

Some examples of ratio variables are length measures in the english or metric systems, time measures in seconds, minutes, hours, etc., blood pressure measured in millmeters of mercury, age, and common measures of mass, weight, and volume (see Figure 1.1).

What is a discrete quantitative?

Quantitative discrete variables are variables for which the values it can take are countable and have a finite number of possibilities. The values are often (but not always) integers.

What is quantitative discrete data?

All data that are the result of counting are called quantitative discrete data. These data take on only certain numerical values. If you count the number of phone calls you receive for each day of the week, you might get values such as zero, one, two, or three.

What is discrete data example?

Examples of discrete data

The number of customers who bought different items. The number of computers in each department. The number of items you buy at the grocery store each week.

What are quantitative examples?

Quantitative Information – Involves a measurable quantity—numbers are used. Some examples are length, mass, temperature, and time. Quantitative information is often called data, but can also be things other than numbers.

What are examples of qualitative?

Qualitative data describes qualities or characteristics. It is collected using questionnaires, interviews, or observation, and frequently appears in narrative form. For example, it could be notes taken during a focus group on the quality of the food at Cafe Mac, or responses from an open-ended questionnaire.

What makes a variable discrete?

A discrete variable is a variable whose value is obtained by counting. Examples: number of students present. number of red marbles in a jar.

Is pulse rate a quantitative variable?

These are also called ordinal variables. Measurement (quantitative) variables examples: Height, temperature, IQ, pulse rate.

Is air pressure continuous or discrete?

Barometric (atmospheric) pressure can take on any value within physical constraints, so it is a continuous random variable. e. The number of registered voters who vote in a national election is countable and is therefore discrete.

What type of data is blood pressure quizlet?

It can be ordinal, interval or ratio types. Examples of continuous variables are blood pressure, height, weight, income, and age. Rank-ordering data simply puts the data on an ordinal scale.

What is quantitative variable?

Quantitative variables are any variables where the data represent amounts (e.g. height, weight, or age). Categorical variables are any variables where the data represent groups.

Is blood pressure ordinal or interval?

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.

How is blood pressure measured indirectly?

In clinical practice, blood pressure is usually measured indirectly. The two most common methods of indirect blood pressure measurement are Doppler ultrasound using a sphygmomanome- ter and oscillometry. Both techniques use an inflatable cuff placed around an extremity.

Is diastolic blood pressure a categorical variable?

Age in years – quantitative Gender – categorical Heart rate in number of beats per minute – quantitative Systolic and Diastolic blood pressure – quantitative BMI – quantitative.

What is a continuous quantitative variable?

Continuous variable. 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. For example, the length of a part or the date and time a payment is received.

Are all qualitative variables discrete?

Variables that can only take on a finite number of values are called "discrete variables." All qualitative variables are discrete. Some quantitative variables are discrete, such as performance rated as 1,2,3,4, or 5, or temperature rounded to the nearest degree.
