Essay

What do the class standard deviation values for the oxygen measurements in these ecosystems tell you about the experimental design or the testing procedure? What would you do to reduce the standard deviation value in future experiments?

In the concern of scientific experimentation, most results do not actually conform to the expectation and empirical logic of the experiment thus putting the need for deviation allowance and accurate methodology in the process. In the case of the involved experiment, the resulting class standard deviation values for the dissolved oxygen reading clearly suggest that there have been significant differences in the outcome of the group experiments compared with the class. The said gap in the class standard variation could have been caused by inaccurate reading or a failure to adhere to the proper methodology in the experimentation or even differences in the material used such as the condition of the plant, the animal, or the lighting. It could have been the plants used by this specific group are more robust giving higher dissolved oxygen results than the others. The issue of the environment can also be a significant factor in this situation wherein some location in the laboratory could have given more lighting to a certain experiment giving a different result from the general outcome.

In terms of reducing the deviation results, a more controlled environment could essentially lessen the differences in the result or even taking some measures to better seclude each experiment’s development and design. Taking also more accurate readings, measurements, and procedures can also lessen the factor of class deviation results.

What do the values for the standard deviation of the measurement of CO2 tell you about the experimental design or the testing procedure? What would you do to reduce the standard deviation values in future experiments?

The resulting class standard deviation values for the measurement of CO2 suggests that there has been significant differences in the experiment outcomes of this group compared with the general achieved result in theclass. Though the result for this group shows the expected trend, the difference in their actual figures and the irregular gaps give the presumption of improper handling or inaccurate readings or other factors that could have compromised the experiment designparticularly in this case the condition of the carbon dioxide reagent used and its potency unique or irregular to the entire class group.

In the future, to avoid such significant gaps or deviation from the general class result, stricter adhesion to the experiment design must be followed with careful and accurate readings and using materials that are similar to the entire class thus, achieving outcome that is essentially regular.

What do the values for the standard deviation of the measurement of ammonia tell you about the experimental design or the testing procedure? What would you do to reduce the standard deviation values in future experiments?

Essentially, the values are showing the expected reading trend of the experiment however the actual figures are clearly not showing a realizable outcome in the testing design which could have been caused by inaccurate reading of the empirical data. In this case, the presence of high ammonia content has actually dull proper and accurate reading of the experiment. In this scenario also, one shows false result strongly compromising the particular section in the experiment procedure. In aiding such scenario, closely following the methodology of the experiment and noting the quality of each material used in the testing design must be observed to achieve the expected result of the experiment with empirical results within the regular trend of the class.
