Patient Characteristic* Total Sample (n = 4434) Age, years 49.93 (8.68) Male sex 1944 (43.84) Systolic blood pressure, mmHg 132.91 (22.42) Diastolic blood pressure, mmHg 83.08 (12.06) Use of anti-hypertensive medication 144 (3.29) Current smoker 1944 (43.84) Total serum cholesterol, mg/dL 236.98 (44.65) Body mass index 25.85 (4.10) Diabetes 121 (2.73) * Mean (Standard deviation) or n (%) 2. Complete the following table to compare men and women using data collected at the first examination for each participant (n = 4434). Summarize your results in three to four sentences. Patient Characteristic* Men (n = 1944) Women (n = 2490) Age, years 49.79 (8.72) 50.03 (8.64) Systolic blood pressure, mmHg 131.74 (19.44) 133.82 (24.46) Diastolic blood pressure, mmHg 83.71 (11.44) 82.60 (12.50) Use of anti-hypertensive medication 42 (2.19) 102 (4.16) Current smoker 1175 (60.44) 1006 (40.40) Total serum cholesterol, mg/dL 233.58 (42.36) 239.68 (46.22) Body mass index 26.17 (3.41) 25.60 (4.56) Diabetes 59 (3.04) 62 (2.49) * Mean (Standard deviation) or n (%) 3.Use simple and multivariable linear regression analysis to complete the following table relating the characteristics listed to BMI as a continuous variable. Before conducting the analysis, be sure that all participants have complete data on all analysis variables. If participants are excluded due to missing data, the numbers excluded should be reported. Then, describe how each characteristic is related to BMI. Are crude and multivariable effects similar? What might explain or account for any differences?

Test if there are significant differences in the following risk factors between persons with and without prevalent coronary heart disease (CHD). Summarize the statistical results in the table below and then compare risk factors in persons with and without prevalent CHD. Be sure to indicate what statistical tests were used in the footnote to the table and in a brief summary of a paragraph or less. Patient Characteristic* History of CHD (n = 194) No History of CHD (n = 4240) p-value* Age, years 57.48 (7.42) 49.58 (8.57) <0.001 Systolic blood pressure, mmHg 144.99 (27.03 132.35 (22.03) <0.001 Diastolic blood pressure, mmHg 87.14 (14.33) 82.90 (11.91) <0.001 Total serum cholesterol, mg/dL 243.19 (45.61) 236.69 (44.6) 0.0486 Body mass index 26.83 (4.45) 25.80 (4.08) <0.001 * Mean (Standard deviation). P-values are based on two independent samples t tests.5. Describe the Data collection Methods used in the study6. Please Provide a Summary of the data analysis as a whole . Summary should include pertinent information of all the questions above. This summary should not exceed 300 words.

My Stat lab - 2 sections - 6.1 and 6.2please have knowledge in subject. Should be easy for someone with a background in Statistics

DQ1Reflect on collection of data, data cleansing and preparation activities, and selection and application of models, including challenges/struggles, procedures, approach, etc.How do you know that the data you are collecting will be useful?DQ2When summarizing your data, how did you decide which visualization tool you would use to best communicate this information (bar graph or line graph)?AssignmentNow that you have identified the business problem, translated it into an analytics problem, identified the data needs, and acquired the data, you will use data that you have found or with the company's permission you can use its data for analysis to resolve the analytics problem. Using one or more of the following software applications (IBM SPSS Modeler, SPSS Statistics, Excel, Tableau, or R), analyze the data so that the findings can be used to address the established business problem in your company.Write a 750-1,000 word paper that includes the following information for your data (ensure that specific screenshots of graphs, tables, etc., are provided):Conduct an exploratory data analysis: What information is contained in the data set?Describe key features of the data and any significant relationships you find.How did you verify that the data was reliable before proceeding?What problems did you find and how did you address them?What relationships did you find in the data?Any missing data?Analyze trends with respect to any appropriate characteristics that you may have discovered.Supplement your description with appropriate charts/figures. Data can be (but are not necessarily limited to) the following:Line graphsPie chartsBar chartsScatter plotsIndicate the steps you have taken to investigate the quality of the data and indicate any variables you have transformed or discarded as a result.Provide a summary that provides a detailed overview of the trends identified based upon the analysis.Segment the data accordingly, if needed, to help describe the data behavior.How are you going to summarize data samples?Provide a detailed statistical summary of all information provided.Provide the raw software files that you used for this assignment.
