Introduction to Probability Theory and Health Statistics
Your specific assignment for this week is to select one type of quantitative health datum to collect from your own life. Some examples of data to collect could be:

1. How many minutes do you spend exercising each day?
2. What is your total daily caloric intake in calories?
3. What is your resting heart rate in beats per minute?
4. How many ounces of water do you drink each day?
5. What is your estimated total caloric expenditure from exercise each day?
6. What is your estimated daily intake of saturated fat in grams?
7. What is your daily systolic/diastolic blood pressure?

Your Task:
1. Choose one variable that varies measurably from day to day. Be sure to specify the units of measurement, and state how it will be gathered.

2. Then collect at least 5 days’ worth of data on that one variable. For example, if your variable is how many minutes you spend exercising each day, simply record the number of minutes that you spend exercising each day during the sampling period. Be sure to save this data for use in remaining SLP assignments. The more data points that you gather during the session, the better.

3. Describe the data you have collected and its importance in relations to individual/population’s health.

Introduction to Probability Theory and Health Statistics

1. Choose one variable that varies measurably from day to day. Be sure to specify the units of measurement, and state how it will be gathered.
Daily systolic/diastolic blood pressure? A variable is simply what is being observed or measured. An observations of blood pressure is an example of a quantitative or continuous variable; any value within a specific range are always numeric and are on a real scale with clearly defined subdivisions. Blood pressure is continuous and arbitrary, therefore it can be changed to meet measurement needs. (Norman, G.R. et al 2008). In submission to the requirements of this paper, blood pressure (BP) and pulse (P) were taken for five (5) consecutive days; commenced on the morning hours between 8am and 9am (EST), Monday, October 19, 2015 and ended Friday, October 23, 2015. To ensure the accuracy of the measurements, BP/P was taken at work by co-worker, Maria Gonzalez, Clinical Phlebotomist, who monitored and recorded the data on the dates specified. The monitoring of BP/P was taken at work, in the early mornings of the work week, and prior to the opening of clinical laboratory and the arrival of patients for their scheduled pathology appointments.

Be sure to save this data for use in remaining SLP assignments. The more data points that you gather during the session, the better.
The Table below summarizes the descriptive statistics for BP and Pulse monitoring.

Describe the data you have collected and its importance in relations to individual/population’s health. The data collected is numerical, quantitative variables also called a continuous variable, measured within a specific time frame. Accurate measurements of blood pressure is essential to classify individuals, to ascertain blood pressure, the related risks, and to guide management. There are potentially 3 measures of blood pressure that could contribute to the adverse effects of hypertension. The first is the average level, the second is the diurnal variation, and the third is the short-term variability. The measure of blood pressure that is most clearly related to morbid 2

events is the diurnal variation, there is also evidence that suggests that hypertensive patients whose pressure remains high at night are at a greater risk for cardiovascular morbidity. Blood pressure is characterized by an array of spontaneous variations, values vary markedly within the 24 hours because of day-night changes but, also because of differences among hours, minutes, and even adjacent beats. They also show variations over more prolonged periods because of differences among days, months, and seasons. (Wolf-Maier K et al 2003). The health risks attributable to increasing blood pressure in adults are continuous, beginning at 115/75 mm Hg. A blood pressure of greater than or equal to 140/90 mm Hg, are regarded as indicators of hypertension. The readings from the data collected stipulates the subject falls in the category of being diagnosed with hypertension. Blood pressure determination continues to be one of the most important measurements in all of clinical medicine and is a major risk factor for coronary heart disease, stroke, and renal failure and, affects approximately one-third of the American population.

(2007). Statistics for health care research: A practical workbook. Edinburgh: Elsevier Saunders. Topic 1 DQ 1: How can graphics and/or statistics be used to misrepresent data? Where have you seen this done? Statistics are used everywhere, every day to represent a multitude of data, or study sample. Sample characteristics are the traits that depict the study sample and can be portrayed in either some type of table or in an article (Grove, 2007). “Descriptive statistics are used to generate sample characteristics, and the type of statistic used depends on the level of measurement or the demographic variables included in the study” (Grover, 2007, p.75). It is this information and data that is presented can be misrepresented, either unethically or simply because the data is misunderstood. According to Statistics (2013), data can be misrepresented three ways: 1) misunderstanding the data presented, 2) using incomparable definitions, and 3) by deliberately misinterpreting the data presented, especially if it is a biased representation. An example of misunderstanding the data presented could be someone that is researching crime statistics in an area where they are looking to relocate and raise a family; if they do not understand the manner in which the data is being presented, it could be more than easy for them to...

...truth. 3. Test Statistic - A sample statistic (often a formula) that is used to decide whether to reject H0 . 4. Rejection Region- It consists of all values of the test statistic for which H0 is rejected. This rejection region is selected in such a way that the probability of rejecting true H0 is equal to α (a small number usually 0.05). The value of α is referred to as the level of significance of the test. 5. Assumptions - Statements about the population(s) being sampled. 6. Calculation of the test statistic and conclusion- Reject H0 if the calculated value of the test statistic falls in the rejection region. Otherwise, do not reject H0 . 7. P-value or significance probability is defined as proportion of samples that would be unfavourable to H0 (assuming H0 is true) if the observed sample is considered unfavourable to H0 . If the p-value is smaller than α, then reject H0 . Remark: 1. If you fix α = 0.05 for your test, then you are allowed to reject true null hypothesis 5% of the time in repeated application of your test rule. 2. If the p-value of a test is 0.20 (say) and you reject H0 then, under your test rule, at least 20% of the time you would reject true null hypothesis. 1.

...Goudy RES/351 July 6, 2015 Tracy Sipma Descriptive statistics Descriptive statistics suggests a straightforward quantitative outline of a data-set which has been gathered. It helps us comprehend the experimentation or data-set in-detail and tells people concerning the mandatory details that help show the data perceptively. Descriptive statistics, we just convey exactly what the data reveals and tell us. Most of the statistical averages and numbers we estimate are essentially illustrative averages. For instance the Dow Jones Industrial tells us about the typical performance of select firms. The grade-point avg. tells us about the typical performance of a pupil in school. The GDP growth rate tells us about the typical performance of a state. Therefore illustrative statistics attempts to catch a sizable group of observations and offers us some concept concerning the data-set. Descriptive statistics aims to describe data set information with summary graphs and tables (Linda Hollis, n.d.). Inferential Statistics Inferential statistics includes drawing the correct conclusions from your statistical evaluation that's been performed using descriptive data. Ultimately, it really is the inferences that make studies significant and this element is dealt with-in inferential data. Most forecasts of the potential and generalizations of a population by analyzing a smaller sample come under the scope of inferential statistics.

...easily think of two people you know where the shorter one is heavier than the taller one. Nonetheless, the average weight of people 5'5'' is less than the average weight of people 5'6'', and their average weight is less than that of people 5'7'', etc. Correlation can tell you just how much of the variation in peoples' weights is related to their heights. Although this correlation is fairly obvious your data may contain unsuspected correlations. You may also suspect there are correlations, but don't know which are the strongest. An intelligent correlation analysis can lead to a greater understanding of your data. Techniques in Determining Correlation There are several different correlation techniques. The Survey System's optional Statistics Moduleincludes the most common type, called the Pearson or product-moment correlation. The module also includes a variation on this type called partial correlation. The latter is useful when you want to look at the relationship between two variables while removing the effect of one or two other variables. Like all statistical techniques, correlation is only appropriate for certain kinds of data. Correlation works for quantifiable data in which numbers are meaningful, usually quantities of some sort. It cannot be used for purely categorical data, such as gender, brands purchased, or favorite color. Rating Scales Rating scales are a controversial middle case.

...the Development of Statistics September 2007 This paper has been prepared by the Development Data Group of the World Bank and the PARIS21 Secretariat at the request of the PARIS21 Steering Committee. It is part of the follow-up to the Third International Roundtable on Managing for Development Results in Hanoi in February 2007 and the meeting on scaling up support for statistics held during the World Bank and IMF Spring Meetings in Washington in April 2007. Scaling-up Support to Statistics Executive summary This paper briefly discusses why scaling up investment in National Statistical Systems is needed and then focuses on how this could be achieved by applying a system-wide approach, drawing lessons from the Sector-Wide Approaches (SWAps) used successfully in areas such as health, education and agriculture. It argues that an effective and efficient National Statistical System is essential for managing for development results. Investments in statistics are needed, just as much as in areas such as financial management and procurement. National Statistical Systems provide the data needed to develop appropriate policies, to target scarce resources, to measure progress, to make effective use of aid and to monitor and evaluate outcomes. At the Third International Roundtable on Managing for Development Results, which was held in Hanoi in February 2007, participating country teams emphasized that to be successful any scaling up of support to statistics must be grounded in...
