How do you use statistics in your daily life, either at home or in your current or future career? Find and discuss at least two examples of statistics that are used in your career field or in your daily life. Do you feel like statistics are a vital part of your current or future career? What about your daily life? Why or why not?

Present two different types of data, or variables, used in the health field. Examples could be blood pressure, temperature, pH, pain rating scales, pulse oximetry, % hematocrit, minute respiration, gender, age, ethnicity, etc. Classify each of your variables as qualitative or quantitative and explain why they fall into the category that you chose. Also, classify each of the variables as to their level of measurement–nominal, ordinal, interval or ratio–and justify your classifications. Which type of sampling could you use to gather your data? (stratified, cluster, systematic, and convenience sampling)

Description: Students will graph a quadratic equation and draw conclusions based on the graph. Objectives: Graph and evaluate a quadratic function. Instructions: Step 1: Respond to the following: If a manufacturer can produce a certain item for $7 and sell the item for x dollars, the profit per item will be x – 7 dollars. If it is then estimated that consumers will buy 25 – x items per month, the total profit will be: Total Profit = (number of items sold)(profit per item) = (25 – x)(x – 7) Use this information to create a quadratic equation. Then graph your equation, and based on the graph, what value of x will create the greatest profits? What will that profit be? What part of the graph did you use to find this information? Explain how this process could be useful in other scenarios.

An important distinction is made in between quantitative and qualitative independent variables. Please discuss each of these types of variables, giving examples of each, and please explain why this distinction is so important to the study of multivariate statistics.

For this Critical Thinking assignment, you will analyze survey results using concepts

This course exercises many skills related to understanding statistical procedures and analysis. For this assessment, you have the opportunity to incorporate many of the skills discussed in this course into a research report. You will use the GSS Explorer website, form a hypothesis, and then conduct a statistical analysis on the data in order to determine whether the hypothesis is accurate or not. In addition, you will record the results and make conclusions based on the hypothesis you originally designed. Having the ability to connect all the concepts to apply research and real variables ensures you understand the various methods of statistical analysis. Preparation You will use data from the GSS Data Explorer website, which contains archival data. Archival data is pre-existing data that has been collected by another individual or organization and is available to be analyzed, enabling you to draw new conclusions about the data. The website requires you sign up for an account. If you need help with sign-up, watch GSS Data Explorer Instructions, which walks you through the process of creating an account with the website (free of charge), finding your variables for the research report, and extracting the data to an Excel spreadsheet. Decide Your Variables Begin by selecting two variables of your choice from the following list of variables—it’s recommended that you choose one from List A and one from list B. Note that “r” represents the participant. List A Labor force status (wrkstat). Marital status (marital). R’s highest degree (degree). Have gun in home (owngun). How often does r read newspaper (news). Www hours per week (wwwhr). List B People helpful or looking out for selves (helpful). People fair or try to take advantage (fair). Can people be trusted (trust). Days of poor mental health past 30 days (mntlhlth). Told have depression (depress). Happy or unhappy with life today (hapunhap). R’s rating of life overall now from 0–10 (lifenow). R’s quality of life (quallife). R’s mental health, mood, and ability to think (hlthmntl). In the past 7 days, how often r has been bothered by emotional problems (emoprobs). How often r was unhappy or depressed in past 4 weeks (unhappy). If you want to report demographic information on your participants (optional): Respondent’s sex (sex). Respondent’s race (race). Extract Your Data When you decide on your variables, extract your data from the GSS Data Explorer website. If you need help, watch GSS Data Explorer Instructions. Be sure to name your project for this course. After you’ve extracted your data, design a research topic involving the two selected variables. For example, if you select “condition of health” and “How often r attends religious services,” you may want to research how religion impacts an individual’s health and wellness. Resources Be sure to visit the Resources for this assessment to help you with the steps of your research report, such as the literature review, determining which statistical test to use, and writing your results in APA style. Instructions The Research Report Template [DOCX] will help you include the following in your paper. Introduction. Literature Review. Search for relevant, scholarly articles that support your hypothesis and argument. Consult the Resources for this assessment for guidance on searching for sources. You should have a total of six sources. For each source, write 1–2 paragraphs that includes a main idea, evidence from the source, and an analysis. Hypothesis. Include both null and alternate hypotheses. Methods. Participants. Describe the number of participants in the study. For this archival data project, the number of participants refers to the number of participants who responded to both of your selected variables. Measures. Discuss the measurement you chose from your work throughout the course. Data Analysis. Explain the form of analysis that you used to manipulate your data. Consider the following questions in your explanation. From the point that you had the raw data, what test did you run? Why did you select that test? Why did you choose to manipulate the data? How did you manipulate the data? What results did you desire? Results. Report the results of your statistical analysis. Reflect on whether your null hypothesis or alternate hypothesis is correct. Make a conclusion in regard to the relationship between the variables. Discussion. Discuss your results in relation to the following: How do your results compare to other research studies? How can your results be generalized? What were the limitations of the study? Is your research valid and reliable? Or, how would you evaluate the validity and reliability of your study? Submission Requirements Submit the completed 6–8 page template as your deliverable for assessment. Be sure that you have cited all sources in APA style.

Assignment Assignment: Descriptive Statistics Due Week 7 and worth 140 points Visit one of the following newspapers’ websites: USA Today, New York Times, Wall Street Journal, or Washington Post. Select an article that uses statistical data related to a current event, your major, your current field, or your future career goal. The chosen article must have a publication date during this quarter. The article should use one of the following categories of descriptive statistics:  Measures of Frequency – Counting Rules, Percent, Frequency, Frequency Distributions Measures of Central Tendency – Mean, Median, Mode Measures of Dispersion or Variation – Range, Variance, Standard Deviation Measures of Position – Percentile, Quartiles Write a two to three (2-3) page paper in which you: Write a summary of the article. Explain how the article uses descriptive statistics.  Explain how the article applies to the real world, your major, your current job, or your future career goal. Analyze the reasons why the article chose to use the various types of data shared in the article.

Using the information provided below, create an APA formatted paper with sections addressing the following. Be sure to discuss the substantive interpretation of the bivariate and multivariate hypotheses tests.• Question: What is your question or puzzle, and why does it matter?• Theory: What is your causal theory linking your independent and dependent variables?o It’s okay to be testing/supporting/tweaking an existing theory.o What are your variables? How are they defined conceptually?• Alternative Explanations: What are the alternatives to your theory? What evidence would falsify your theory and/or support alternative theories?• Operationalization: o How are you measuring your DV? Your IV?o What are variables relating to potential alternative explanations?o Why are these measures most appropriate? o What are your units of observation? o Do they represent a population or a sample?• Hypotheses: Formally state the null and alternative hypotheses you are testing.• Bivariate hypothesis test(s): Report the results of an exploratory bivariate hypothesis test of the relationship between your IV and DV.• Multivariate hypothesis test(s): Report the results of your multiple regression (maximum likelihood) analysis.o Provide the slope coefficients, p-values, R-squared, nTheory Foreign aid is defined as the assistance in money that a specific country transfers to another country. Those, as mentioned above, can assume the form of a gift, loan, or grant. Foreign aids have the capacity within the context of contributing to the engagement with civil society and democratization through the provision of assistance attached with the strengthening of the executive powers, the process of election, improvement of education, and increase of the per capita income. There is less evidence on the factors affecting the promotion of foreign aid towards democratization. There is further evidence on the fact that there exist few society organizations have a direct engagement attached to the process of policy formulation and making an impact on the outcome of policy. On the other dimension, there is further less information provided within the literature review on how democratization is influenced by foreign aid. On the different aspect, there exists limited research that is attached to the relationship that exists between the civil society organization that operates in the countries that receive foreign aid.Hypotheses H0: The determinant factors contribute to democratization and the engagement and civil society engagement in receiving democratic aid.  H1: The determinant factors don’t contribute to democratization and the engagement and civil society engagement in receiving democratic aid. Unit of Analysis  The unit of analysis will be country-year of states receiving foreign aid. This unit was chosen to determine if there is a relationship between the years that states receive foreign aid and CSO participation and democratization over the same years. Independent variable Foreign Aid – https://data.worldbank.org/indicator/DT.ODA.ODAT.PC.ZS Net official development assistance (ODA) per capita consists of disbursements of loans made on concessional terms (net of repayments of principal) and grants by official agencies of the members of the Development Assistance Committee (DAC), by multilateral institutions, and by non-DAC countries to promote economic development and welfare in countries and territories in the DAC list of ODA recipients CSO Strength – Society Participation Index measures if CSOs are routinely consulted by policymakers, their involvement of people in CSOs, including women, and if legislative candidate nomination within party organization is highly decentralized or made through party primaries. Dependent variable  Democracy indicies – indices measure the extent that electoral, liberal, participatory, deliberative, and egalitarian democracy has been achieved. Using this information, we can measure improvement in democracy in states where more established CSOs are active.
