Complete The Analysis Of Exploratory Data Analysis

  Statistics Project

This project is to help you apply concepts to real world, real data analysis. In the real world computers do most of the hard work for statisticians.  This project will help you understand how the informative decision is made using data analysis.  After completing this project, you will be able to determine which statistical procedures are appropriate; and use the software (Excel, SAS, SPSS, Minitab, and in our course StatCruch) to carry out the procedures and interpret the output.

• Carefully read through the following data

Previous studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. These stresses come from a combination of physical and social sources such as traffic congestion, incessant time pressure, and unruly passengers. A study examined the effects of an intervention program to improve the conditions of urban bus drivers. Among other variables the researchers monitored diastolic blood pressure of bus drivers in downtown Stockholm, Sweden. The data, in millimeters of mercury (mm Hg), are based on the diastolic blood pressures obtained prior to intervention for a random sample of 25 bus drivers in the study.
