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.
In practice, almost all chemical compounds and materials are subject to biodegradation, the key is the relative rates of such processes-minutes, days, years, centuries... A number of factors determine the degradation rate of organic compounds.Salient factors include light, water and oxygen.lthough often conflated, biodegradable is distinct in meaning from compostable. While biodegradable simply means to be consumed by microorganism, compostable makes the specific demand that the object break down under composting conditions.
