Why is it valuable to know if you are considered Prehypertensive?
Prehypertension can serve as an early warning for patients and doctors. It is a sign of possible changes that could lead to heart disease. The pressure caused by constant prehypertension can change blood vessels and the heart in a damaging way. Prehypertension can also stress the kidneys.
Why the heart rates of different people are different when exposed to the same stressor or to the same physical activity even though their resting heart rates are identical?
The heart rates of different people are different when exposed to the same stressor or to the same physical activity, even though their resting heart rates are identical because each person’s brain react to stressors and physical activity differently.
What is the typical resting heart rate for a healthy individual?
The normal resting heart rate for adults over the age of 10 years, including older adults, is between 60 and 100 beats per minute (bpm). Highly trained athletes may have a resting heart rate below 60 bpm, sometimes reaching 40 bpm. The resting heart rate can vary within this normal range.
What did you need to keep constant in your experiments Why was it important to keep these factors constant?
The same person, the same amount of time between readings and for the readings, the same number that is pumped to in the beginning, and the same temperature. These factors must remain constant because if not other factors that are not the independent variables could change the data, and the data would be corrupted.
What is the purpose of a constant in an experiment?
A controlled or constant variable does not change throughout the course of an experiment. It is vitally important that every scientific experiment include a controlled variable; otherwise, the conclusions of an experiment are impossible to understand.
What should be kept constant in an experiment?
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
What is the difference between a constant and a control in an experiment?
The difference between Constant and Control is that a constant variable does not change throughout an experiment. A control variable, on the other hand, can change but is deliberately kept constant to isolate the interrelation between an independent variable and a dependent variable.
What is an example of the control group?
A simple example of a control group can be seen in an experiment in which the researcher tests whether or not a new fertilizer has an effect on plant growth. The negative control group would be the set of plants grown without the fertilizer, but under the exact same conditions as the experimental group.
What is the primary reason to include a control group in an experiment sociology?
The control group (sometimes called a comparison group) is used in an experiment as a way to ensure that your experiment actually works. It’s a way to make sure that the treatment you are giving is causing the experimental results, and not something outside the experiment.
What is the dependent variable in the marshmallow test?
To create an experiment derived off the original delayed gratification experiment conducted by Walter Mischel in the 1960s and 1970s at Stanford University, we chose to use grade eights (approximately age 13-14) and grade ones (approximately age 5-6) to be our independent variable, and used large white marshmallows to …
What does the marshmallow test prove?
This is the premise of a famous study called “the marshmallow test,” conducted by Stanford University professor Walter Mischel in 1972. The experiment measured how well children could delay immediate gratification to receive greater rewards in the future—an ability that predicts success later in life.
