As BOD5 depends on the growth of microbes the test can be adversely affected by
* Temperature * Toxics * Turbidity * Light * Agitation * Species of Microbe * Microbial contamination by a wild population
* Nature of the organics present * Skill of the analyst * Data entry errors * Lack of blanks and samples of known strength
* Equipment accuracy and maintenance

What are the factors that may affect the rate at which the salt dissolves in water?
Factors that may affect the rate at which salt dissolves in water include temperature (higher temperatures generally increase the rate of dissolution), agitation or stirring of the solution (increases contact between salt and water molecules), surface area of the salt particles (finely ground salt dissolves faster), and the concentration of the salt solution (higher concentrations may slow down the dissolution rate).

What term is given to the different factors that may affect the results of an experiment?
Variable
Why does the ambient temperature need to be measured before and after the experiment?
You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.
Define manipulated responding and controlled variables?
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
Why does the ambient temperature need to be measured before and after the?
You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature.

How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
