Introduction
The HSE demanded a statistical report and analysis of the laboratory data, which could be used as evidence of particular sectors of chemical industry causing potential health hazards for their employees. For the purpose of this analysis a sample of people coming from four different sectors of chemical industry had their blood tested for LDH-1 and LDH-5 levels (Intercellular enzyme that determines cell damage in various organs). The degree of organ damage, in this case liver damage, can be simply assessed by looking at the values of the ratio of those two enzymes: the higher the ratio of LDH-1 and LDH-5 is, the worse the degree of liver damage is (nurseslearning.com). This is how we can compare worker’s health state and

One method of assessing the level of liver damage is to measure the ratio of LDH-5 to LDH-1.
To begin the statistical analysis of the data provided, we need to present the statistical description of it, take a general look at the means and medians for each sector and test the normal distribution of the data to see if we can undertake any further test.
As presented in the boxplot and in the descriptive statistics, the highest mean of the LDH1 to LDH5 ratio is associated with plasticizer manufacturing. Further examination and testing of the data is necessary to determine whether there is a significant statistical difference between each industry and health hazard associated with it, measured by LDH enzyme levels.
First of all it is worth to take a look at any outliers that may affect a distribution of the data.
Outliers affecting distribution:
De-greasing outliers:
Female,34, 2 years of service
Dry cleaning outliers:
Male,33,15 years of service
Female, 60, 34 years of service
Plasticizer manufacturing outlier:
Male, 35, 14 years of service
The data set seems to have many outliers and what is more the Q1 and Q3 – the quartiles are of a different distance from the median, which makes the whole distribution unsymmetrical. What is more, the whiskers are of a different length except for plasticizer manufacturing, which is generally the most symmetrical one, and is the closest to the
Both qualitative and quantitative research methodology will be use to investigate the hypothesis. The use of case study, questionnaire, interview and statistical analysis will be used to observe and asks questions about the views of the micro, meso and macro levels of society on my topic. Problems that could occur with these methodology is not having enough adequate data to proceed the with each analysis. Secondary research will be used to make subjective judgments about what data is useful and what is not for the motive for the research process.
In this activity you will collect data and then perform statistical analyses to determine measures of central tendency and variation of the data. You will also represent
5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?
Refer as needed to the material in Chapters 12 and 13 of the textbook. Keep the following tips in mind as you research data, as well as organize, analyze, interpret, and illustrate these data:
Grade 1: This grade is where the ankle will be tender and swelling may occur however the ligaments will not be torn however there may be little tear.
The data that I have is accurate because by looking at the histogram the graphs are perfectly skewed and, the data make sense, if I compare the data to the median and the IQR. And to find IQR subtract Quartile 3 from Quartile 1. The purpose of using mean value to see if the graph is symmetric or not but, in my case I do not have symmetrical graph or Boxplot, because it is sensitive to outliers. I choose to use the IQR instead of the standard deviation because it shows what is below the 1st quartile and above the 3rd quartile. To summarize, median and IQR are the best option because they resistant to outliers.
Iterations of analysis eliminated data points that were listed as “unusual observations,” or any data point with a large standardized residual. After 5 iterations, the analysis showed improved residual plots. Randomness in the versus fits and versus order plots means that the linear regression model is appropriate for the data; a straight line in the normal probability plot illustrates the linearity of the data, and a bell shaped curve in the histogram illustrates the normality of the data.
|• Occupational health- Illnesses caused or made worse by work such as dust, cleaning agents, diseases etc. |
Specific health problems associated with the workplace have contributed to the development of Particular health issues connected with the work environment have added to the advancement of the cutting edge safety and health development. These issues incorporate lung infections in diggers, mercury harming, and lung tumor attached to asbestos. Occupational and Environmental Health Professionals have an above normal extent of all day employments. For Occupational and Environmental Health Professionals working all day, normal week by week hours are 42.3 and profit are high - in the ninth decile. Unemployment for Health Professionals is underneath normal. H&S Professionals have an expansive extent of specialists amongst individuals in the 25-34 age section, making it an energetic and dynamic workplace. The unavoidable consequence of the expanded consideration given to safety and health is that bigger organizations are utilizing safety and health professionals and all organizations big or small are relegating these obligations to existing representatives.
It is understood that manual workers endure more work related injuries than non-manual workers. Recent studies to support this claim come from Clapp et al (2005) who indicate that a probable 12 of cancer deaths are workplace related, also, Meldrumm (2005) found that working conditions cause up to 20 of lung cancer deaths (Holborn, Burrage and Langley, 2009).
Identify and use at least two appropriate statistical analysis techniques (such as conversion of leads to sales, correlations between variables, measures of central tendency, time series analysis, etc.) to identify market trends and development based on the data that you have collected. Your report should describe why you selected the statistical analysis techniques to identify market trends and developments.
This was a cross-sectional study done to determine the relationship of 1,2-Dichloropropane (1,2-DCP) and cholangiocarcinoma in Japanese men working in a printing company. The researchers took men who had developed the disease already, compared their liver and bile duct samples to those of healthy individuals, and found some noticeable differences in those who were more exposed to 1,2-DCP. They had a test group of 8 men with cholangiocarcinoma and a control group of 13 human livers from autopsy files in order to do an immunohistochemical analysis to determine the effects of 1,2-DCP on the genes and proteins. They chose the sample that they did because
Many scientific researchers have said that our environment has been filled with toxic chemicals, which us humans have had a part of. There are many different issues that should concern us surrounding these toxic chemicals. The major concern is that many of these toxic chemicals have been claimed to be causing damage to the health of humans and even other life forms. Another concern is that most of the theses toxic chemicals have just recently been produced; and by our environment changing everyday there is no telling what effects these toxic chemicals may have in the long run on the public 's health. Just about all of these toxic chemicals exist in the way they do because of humans. As humans we practice a lot of different activities that cause toxic chemicals to pollute our environment such as, agriculture, industrial, and many domestic activities as well. Many of the toxic chemicals that we produce and use don 't get used in a effective way, which causes them to be wasted, left abandoned, and disposed of. When toxic chemicals are not disposed of properly they effect the environment and the public 's health in a negative way.
Furthermore, the rate of on the job accidents and injuries is likely to increase due to the use of alcohol. According to the Occupational Safety and Health Administration, between 10 and 20 percent of workers who die on the job test positive for alcohol or other drugs, and cites construction, mining, and manufacturing – some of the industries which are already at a high risk for occupational
Pharmaceutical industry is a science organisation that research and develop medicines to help improve people’s life. There are four departments in pharmaceutical. They are researching, development, production and marketing. In this report we will be going to investigate only 2 of these departments. They are research and manufacturing. This investigation will include the risk on health and safety in both departments and how they are similar or different to each other. We will be talking about how to prevent or decrease the risk of it happening and the cause of the hazard. Also we will be talking about how it affects the employer and the employees.
