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.
A âbiodegradableâ product has the ability to break down, safely and relatively quickly, by biological means, into the raw materials of nature and disappear into the environment. These products can be solids biodegrading into the soil (which we also refer to as compostable), or liquids biodegrading into water. product that is âcompostableâ is one that can be placed into a composition of decaying biodegradable materials, and eventually turns into a nutrient-rich material. It is almost synonymous with âbiodegradableâ, except it is limited to solid materials and does not refer to liquids.
