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. Standard Deviation: This is a measure of variability in a population. A low standard deviation means that most of the data points are very close to the same value.
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.
Generally speaking, a material is biodegradable if can be decomposed by biological means -- typically, by bacterial action. That's a very loose definition, because it doesn't specify anything about how fast the process must occur, or what the chemical nature of the end result of the process must be.nfortunately, by itself the term means whatever the manufacturer wants it to mean. If the label does not define biodegradable, then it is undefined, which is a diplomatic way of saying the term is meaningless.
