Differences in Blood Pressure between
Brachium and Antebrachium
written by actual grade school students. We should be very proud of them!!!
Today we are doing an experiment on what the difference is between blood pressure in the brachium and blood pressure in the
antebrachium.
Hopefully you will learn from this article the:
Definition of mean and standard deviations.
The difference between blood pressure in the brachium and
antebrachium using standard deviation.
And the formulas for mean and standard deviation.
Terminology:
Mean: The average of a set of numbers. Calculated by adding
all the numbers together [the sum] and then divided by the total
amount of numbers. (1). 6+5+4=15 2). 15 divided by 3 is 5)
Standard Deviation: (represented by the symbol σ) the standard deviation is what measures the difference [or range of error] between the data set and the mean of the data. If there was
a data set of numbers (e.g. 1, 3, 2, 2, 1, 3, and 9), then the standard deviation would most likely be high, because of the 9. If we
got rid of the 9, the standard deviation would change to something very low.
