Dissolved Oxygen Content and Fish Populations in Water Coursework

Dissolved Oxygen Content and Fish Populations in Water - Coursework Example 6. Analyze results – Assume that your experiment produces results identical to those seen in Table 4, what type of graph would be appropriate for displaying the data and why? 6. Analyze results – Assume that your experiment produces results identical to those seen in Table 4, what type of graph would be appropriate for displaying the data and why? The best type of graph to be used will be a line graph. This type of graph best illustrates trends or behavior of the dependent variable (fish) against varying oxygen levels. The line graph helps the researcher easily monitor increases and declines in the variable over time.   7. Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!). For oxygen levels of between 0 and 4 ppm, the graph rises steadily but for values between 4 and 12 ppm, there is a sharp rise. However, there is a significant drop between levels of 12 and 14ppm, before again showing a steady rise between levels of 14 and 18ppm.   8. Draw conclusions - Interpret the data from the graph made in Question 7.   What conclusions can you make based on the results of this graph? Based on the results, fish thrive well in water with dissolved oxygen concentrations of about 12ppm. However, when the oxygen level is raised above this level, there is no significant increase in the number of fish but instead; a drop in fish populations may be witnessed. Therefore, 12ppm is the optimal level of dissolved oxygen for fish survival.  9. Draw conclusions – Assuming that your experiment produced results identical to those seen in Table 4, would you reject or accept the hypothesis that you produced in question 3?   Explain how you determined this. If my experimental results were to be identical to the above, I would accept my hypothesis. This is because the highest population of fish is witnessed at 12ppm dissolved oxygen level. This means that any values below the 12ppm will lead and this supports my hypothesis.

Employee Relations and Employee Law - Essay Example The latter was largely unpopular with employers and some employees but provided a lot of billing time to the legal fraternity due to its intricate and indefinite procedures that were wrought with problematic clauses. An Associate at Mogers Associates, Tim Gofton observed that, ‘The complexity of the SDRP and the wide interpretations given by Tribunals to important areas of the SDRP (such as supposedly straightforward issues such as what constitutes a ‘grievance’) pushed employees towards seeking legal advice. This in itself pushed parties further away from resolution’ (Gofton, 2009 p.2). For the second time in five years, dispute resolution between employers and employees will be radically overhauled through an introduction of a process that has less stringent measures to the defaulting persons or entities when compared to the earlier process. While a majority of the players have welcomed the new forum for resolution of grievances, others have questioned the ambiguities encompassed in the new code which might lead to further escalation of grievance claims like in the earlier process (an increase by 40 - 65 percent within the last two years). Tynan (2009), however asserts that ‘the code is certainly less prescriptive than the old statutory dispute resolution procedures (SDRPs) that promoted fixation on procedural compliance rather than working actively to resolve the dispute.’(Tynan, 2009, p. 1). The formation of the Advisory, Conciliation and Arbitration Service (ACAS) in 1975 was preceded by a period of great turmoil in the relationships between employers and their staff. Large-scale industrial unrest in the late 1970s and 1980s was widespread due to lack of an agreeable dispute or grievance resolutions mechanism between the employers and employees. The government as a result formed ACAS through the Employment Protection Act to act as the arbitrator in the many highly volatile national strikes that were paralysing the nation hence sabotaging
