Report on The Correlation of physical strength to perfomance on physically demanding jobs - Essay Example

Physically demanding jobs like those that can be obtained in the armed forces, emergency rescue, construction, heavy-equipment industries and the like require a high level of physical capabilities. Occupations that involve long and cyclical duties such as lifting, carrying, pulling and pushing can potentially cause cumulative trauma disorders such as “back pain, sprains, strains, carpal tunnel syndrome, and neck pain” (Nindl & Sharp, 2011). Understandably, when workers are blighted by physical traumas and injuries, they become less effective in carrying out their duties and responsibilities; hence, it could have a potentially negative effect on the job performance on the whole, and eventually on the entire organization.

So, this paper shall elaborate on the correlation between physical strength of workers and job performance on physically demanding jobs. In order to clearly and accurately demonstrate a decisive inference on whether a correlation exists or not, this paper shall focus on two measures: arm strength and grip strength. Data Set No. 18 S.

For the first calculation of the mean score, that is, (x, y, z), ratings have been included in order to identify the significance of ratings in determining the correlation between arm and grip strength and job performance.

Nevertheless, to find if ratings do have a substantial effect on the overall job performance, a second mean score has been measured. Interpretation Scatter plots could have been utilized in order to graphically display the relationships between the strength scores and ratings, and how the two measures relate with ratings and work simulation scores. But, the table itself can already tell enough that participants with lower strength scores have lower ratings from their employers, which could mean that they performed less effectively that their counterparts.

By simply analysing the data, one can automatically conclude that, indeed, there is a correlation between physical strength on performance on physically demanding jobs. Take for instance the comparison of the mean scores and sims between participant 1 and participant 13, participant has got a better simulation and mean score as compared to participant 13 despite the fact that participant 1 got a considerably low ratings. Furthermore, there is not much relationship between ratings and physical strengths.

Some participants who have higher physical strength do necessarily have higher performance ratings from their employers. Such is the case of participant 12 and 15; nonetheless, it
