Is blood pressure a qualitative variable?
No because it is numerical and so therefore it is quantitative
Can hypertension be a qualitative variable?
Yes. You need to define a level of blood pressure which would allow you to classify the patient as hypertensive or not according to whether their blood pressure was above or below that value. You will then have a binary qualitative variable. The classification may need to be bivariate: systolic and diastolic, but that does not change the argument.
How do you calculate the mean arterial pressure?
[Systolic Blood Pressure+(2 x Diastolic Blood Pressure)]/3
What are five sdvantages?
The five advantages are; increase life expectancy, lower heart disease, lower blood pressure, lower rates of diabetes and a more productive life. The advantages are dependent upon the question.
Function ofbulb of sphygmomanometer?
The function of the bulb of a manual sphygmomanometer is to inflate the cuff to stop the flow of arterial blood in the arm so that the blood pressure can be determined. The bulb pumps air into the cuff, causing it to expand against the upper arm. Enough air is pumped into the cuff to stop the flow of arterial blood. The pressure is then slowly released and the point at which blood begins to flow again is recorded as the systolic pressure, representing the highest arterial pressure of the cardiac cycle. Blood flows only with the beating of the heart, however, and further pressure is released until the arterial blood flows freely. This point is recorded as the diastolic pressure, representing the lowest arterial pressure when the heart is at rest.
Is testing a group of 10 volunteers' blood pressure before and after exercise an example of an independent or dependent sample?
What you have written is the test...an independent variable may be something like the type/length of exercise, the dependant variable in this case is the blood pressure.
A medical researcher hypothesis that a newly developed medication can reduce high blood pressure Which of these would most likely be the dependent variable in a study involving this medication?
The blood pressure of the participants in the study
Is blood pressure is a qualitative variable?
No,Blood pressure is a quantitative variable because it is measured in numbers
On which factors is the volume of blood is dependent on?
The volume of blood is dependent on how fast our heart beats. A term called blood pressure is used to determine the pressure at which the heart pumps the blood.
What might be the dependent variable in Shannon lucids experiment?
The dependent variable in Shannon Lucid's experiment could be her cognitive performance or physical health measures, such as reaction time, memory recall, or physiological markers like heart rate or blood pressure. These variables would be influenced by the conditions of the experiment and possibly the effects of space travel on the human body.
Is blood pressure a discrete variable?
No. Because blood pressure is continuous variable. Like temperature, a person's weight and height, the measured value occurs over a continuous scale.
Can emotional state influence blood pressure?
Yes. Blood pressure is dependent on emotional state. Both happy and angry emotional state can trigger blood pressure.
Is blood pressure a qualitative variable?
No because it is numerical and so therefore it is quantitative
Blood pressure that remains between heart contractions?
Diastolic Blood Pressure
What is the difference between high blood pressure and hypertension BTW high blood pressure?
High Blood Pressure and Hypertension are the same thing
What is the medical term meaning difference between the systolic and diastolic blood pressure reading?
Pulse pressure is the difference between the systolic and diastolic blood pressure readings.
Can hypertension be a qualitative variable?
Yes. You need to define a level of blood pressure which would allow you to classify the patient as hypertensive or not according to whether their blood pressure was above or below that value. You will then have a binary qualitative variable. The classification may need to be bivariate: systolic and diastolic, but that does not change the argument.
