Statistical Testing of the Impact of Working Hours and High-Risk Work Essay

Statistical Testing of the Impact of Working Hours and High-Risk Work Conditions on Injury - Essay Example Active work participation and good supervision are some of the important aspects in ensuring hazards are identified and tackled. Nevertheless, training workers is important so as to ensure that they are aware of ensuring safety in their workplaces. In this study, an investigation will be conducted in respect to the relationship between injury rates and different conditions in the workplaces. Although many organizations have some means of preventing and controlling hazards in workplaces, the effect of some conditions such as the total hours allocated for working and the impact of sensitization on high risk work places compared to less sensitization in low risk work places is ignored in many studies (Kennedy et al, 2010). Therefore, this study will investigate the impact that variation in the number of working hours and lack of protective sensitization in low risk workplaces, have on injury rates in workplaces. ... For the degree of risk involved at workplace and injury rates H0: The degree of risk involved is positively associated with the injury rates; H1: The degree of risk involved is negatively associated with the injury rates; These tests of validity for these hypotheses on the basis of results and conclusions reached in the following sections enables the researcher to establish the relationship between identified variables in this research. Method and Results The number of actual hours worked by all employees in the area/team for the 12 month period ending December 31, 2009 were taken and recorded in an excel spreadsheets. Also, operations for supervisors differed in terms of activities and risks. Risk ranged from low (1) office related to high (7) manual material handling activities. Table 1 Risk Range 1 2 3 4 5 6 7 Low ? ? ? ? ? ? ? ? ? High This data was taken and recorded in an excel worksheet as well. Finally, the average rate of injuries per 100 employees over 12 month period was r ecorded on the excel worksheets. Among these variables, the injury rate was taken as the dependent variable while the level of risk and hours worked was taken as the independent variables. The aim of the study is to find out the relationship between injury rate on the one hand and hours worked and risk, on the other hand. In other words, the researcher formulated a statistical model to find out whether the risk and hours worked can be used to predict the rate of injuries in workplaces. The data collected in the excel worksheets are then imported into an SPSS sheet for statistical analysis. The analysis conducted under SPSS includes both descriptive analysis and
