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.
Plastic â material composed mainly of polymers. Biodegradable plastics â plastics that will fully decompose to carbon dioxide, methane, water, biomass and inorganic compounds under aerobic or anaerobic conditions and the action of living organisms.Plastics are typically composed of artificial synthetic polymers. Biodegradation Biodegradation or biotic degradation is a specific property of certain plastic materials-that is, of the polymers these materials are made of. It is a process by which a polymer material decomposes under the influence of biotic components (living organisms).
