Health Statistics: Collecting Accurate Data Using Standard Deviation

For the fourth component of the Session Long Project, write a 2- to 3-page essay in which you continue to collect data for five days. Continue to discuss the spread of the data that you've been collecting by computing the standard deviation of measurements that you've taken so far. Show your work. Be sure to dicuss the concept of standard deviation in response.
I will also need help on slp 5 I just don't get Statistics class I was 3.68 gpa this is going to ruin me.
for reference this is my data from SLP1
Introduction to Probability Theory and Health Statistics
I recently purchased a stethoscope and blood pressure cuff for work
purposes. This allowed me to take my blood pressure at home as well as my pulse to work on this SLP. I started taking my BP and pulse at night just before bed time 10-11pm. This allowed my wife Kari to assist me in taking accurate data. On the 25th of February I stopped working two jobs because my wife has gone back to work after having full knee replacement in October of 2014. This will also allow me to catch up on my assignments and thank you for being so patient with me professor Alla. I chose to do blood pressure and pulse because my diet and exercise is so irregular that it would be nearly impossible to record this data. This data was collected with the help from my wife(Kari) in order to get accurate results. So, here are my results as of March 8th.

Descriptive statistics part one 1: normal curse vulnerability and plotting
The variance in the BP is between 68-87 is 19.
V1=68 V2 =87 (|V1-V2| )((V1+V2/2*100 (calculator soup,2015)
=(l68-87|) ((68+87))*100
=(|-191/)155/2))*100
=0.245161*100
=24.5161% difference

Compute the variance of distribution of measurement and how it distributes itself about the expected vale or mean.
This is not like the range variance uses the data points to determine the distribution (David M. Lane, n.d.). I will show this in the pulse Data since it is a singular set of numbers: 68,70,73,76,77,80,81,82,84,87.
σ2 = variance
∑ (X - µ)2 = The sum of (X - µ)2 for all data points
X = individual data points
µ = mean of the pulse
N = number of data points
There are ten scores in total, so N = 10
σ2 = ∑ (x-µ)2 / 10
The mean (µ) for the ten scores (68,70,73,76,77,80,81,82,84,87), so µ = 77.8
σ2 = ∑ (x-77.8)2 / 10
Now, compare each score (x =68,70,73,76,77,80,81,82,84,87) to the mean (µ = 77.8)
σ2 = [ (65-77.8)2+(70-77.8)2+(73-77.8)2+(76-77.8)2+(77-77.8)2+ (80-77.8) 2+(81-77.8) 2+(82-77.8) 2+(84-77.8) 2+(87-77.8) ] / 10
Subtraction
65-77.8= -12.8
70-77.8= -7.8
73-77.8= -4.8
76-77.8= -1.8
77-77.8= -.8
80-77.8= 2.2
81-77.8= 3.2
82-77.8= 4.2
84-77.8= 6.2
87-77.8=9.2
σ2 = [ (-12.8)2+(-7.8)2+(-4.8)2+(-1.8)2+(-.8) 2+(2.2)2+(3.2)2+(4.2)2+(6.2) 2+(9.2)2] / 10
σ2 = [ 12.8x12.8 + 7.8x7.8 + 4.8x4.8 + 1.8x1.8 + .8x.8+2.2x2.2+3.2x3.2+4.2x4.2+16.2x16.2+9.2x9.2] / 10
σ2 = [163.84 +60.84+23.04+3.24+.64+4.84+10.24+17.64+38.44+84.64]/10
σ2 = 470.76 /10
divide the sum by 10 and we get 47.076 (Siddharth Kalla, 2015)
That is a distribution or mean of 47.076 This is a high variance between the value. I did not expect th
Individual Feedback:
David,
Brief initial posting. Good examples of uses of frequency distribution in the health care setting. Brief discussion on the differences between a normal, positive and negative skew.
Your initial posting has 167 words, which is less than required at least 250 words; and it is not supported by references. Hot links to websites cannot serve instead of properly formatted and cited references. However, your response to one fellow learner has 23 words, which is less than required 250 words; and it is not supported by at least one reference.
I am deducting two points for posting late.
