The bell then slopes down to each side; one side represents scores that are lower than the average, and the other side represents scores that are above the average. Mean: The mean is the average score. The average is calculated by adding all of the scores together, then dividing by the total number of scores.

What are some examples of biodegradable? Some examples of biodegradable include paper, cotton rag, banana peels and many more. These are products that are broken down by micro-organisms found in nature which mean â¦ s they do not harm the environment.
Biofouling or biological fouling is the undesirable accumulation of micro-organisms, algae and diatoms, plants, and animals on surfaces, for example ships' hulls, or piping and reservoirs with untreated water. This can be accompanied by microbiologically influenced corrosion (MIC).ouling by particles from gas aerosols is also of industrial significance. The particles can be either solid or liquid. The common examples can be fouling by flue gases, or fouling of air-cooled components by dust in air.
