Descriptive Statistics Part I: Normal Curves Variability and Plotting (Statistics Project Sample)
First, state whether blood pressure in Table 2A would be a continuous variable or a discrete variable. Explain. Then supposing that the number of women in each of groups (non-users and users) were identified, would the number of women in each category be a continuous variable or a discrete variable? Explain.
Part 2: Use any free online histogram maker* to draw Histograms for the blood pressures of the users and nonusers ages 35 - 44. Discuss one conclusion that can be made about blood pressure and pill use. *Here are some free resources:
Part 3: Based on what you’ve learned in this module about normal distributions, explain why a normal approximation of data would be helpful to view the data. For example, you could describe the steps that one would take to estimate the percentage of women with blood pressures in an age group.
Use the information in the modular background readings as well as resources you find through ProQuest or other online sources. Please be sure to cite all sources and provide a reference list at the end of the paper. Submit the paper as a Word document through the link provided for the assignment.
Length: 2–3 pages typed and double-spaced.
Your Case paper will be further evaluated based on the following criteria:
Each question and or assignment requirement is addressed in the paper.
Accuracy of your answers, key points and supporting discussion
Clarity (Excellent; Good; Average; Poor)
Presents key points that lead to deeper matters and issues.
Integrates several points into coherent conclusions.
Critical Thinking (Excellent; Good; Average; Poor)
The paper demonstrates good understanding and synthesis of the module background material.
Logically incorporates key concepts presented in the background material into the overall analyses, key points and supporting discussions.
Presents well-reasoned conclusions and position as well as convincing arguments in support of the same.
keep in mind while working on your Case Assignments:
Originality and Use of directly quoted material
The purpose of each assignment is for you to present your understanding and synthesis of the background material and key concepts. Accordingly, this must be accomplished substantially in your own words.
Use directly quoted material sparingly and only when preserving the exact words of an author is necessary. For purposes of this course, rarely should directly quoted material represent more than 5 percent to 10 percent of your entire case paper’s content. Composing a paper patched together from mostly quoted material is not acceptable.
Be sure to properly reference all directly quoted material and include the in-text citations. All paraphrased information also requires reference citations at the end of the paraphrased section.
DESCRIPTIVE STATISTICS PART I:
Blood pressure in table 2 A is a continuous variable since it is possible for there to be any value of the blood pressure in the range. The quantitative variable does not have a finite number of values unlike discrete data. Even though the range of blood pressure has been given, it is possible to have a more accurate blood pressure level up to three decimal places, depending on the measuring instruments used in the hospital settings. Theoretically, the measuring instrument may limit accuracy of blood pressure measured, but the variable could be any value within the identified intervals.
Nonetheless, if the number is countable and exact, the data would be discrete and it is unlikely to express their numbers in decimal places (Larson, 2006). The number of women participants is countable and the dichotomous data makes it easier to analyze blood pressure for users and non users of the contraceptive. In other words, the number of women who either use or do not use contraceptive for each blood pressure interval is specific, and it is possible to interpret the data about frequency of blood pressure.
Non users of the contraceptive
Users of the contraceptive
According to Bush (2012), histograms show the extent to which responses are spread out, the most frequent occurrences, those at the center and the distribution’s shape. For users of the pill the 116-120 mm blood pressure category has the highest number of women at 14%, while for non-users it is 16% which is also the highest percen...
