It is very simple to understand and easy to calculate. In simple series, the item values have to be arranged.
If the series contains large number of items, then the process becomes tedious.
For example, we can not find a combined median of two or more groups if the median of different groups are given. In simple series having even number of items, median cannot be exactly found.
(4) It is affected more by sampling fluctuations than the mean as it is concerned with on1y one item i.e. Moreover, the interpolation formula applied in the continuous series is based on the unrealistic assumption that the frequency of the median class is evenly spread over the magnitude of the class interval of the median group.
This fierce debates prompted researchers to look into the feasibility of biomass energy. Research study results learned that biomass has numerous benefits over fossils fuels and it helps cut down emission of greenhouse gases.
Biomass energy, sometimes known as bio energy, is a renewable form of energy produced from organic matter.The energy resulting from gasification and burning of the produced gas is classified as renewable energy if the elements that were gasified originated from biomass.The syngas can be used for heating, generation of electricity and many other functions.Because oxygen is not present during this process, the organic matter doesn’t burn.Instead, it decomposes into 3 forms; a liquid known as bio-oil, a solid known as bio-char and syngas. It’s where bacteria breaks down organic material in the absence of air to produce biogas.The biogas is then captured and combusted to generate energy.Fermentation is the process of converting sugar from organic material into alcohol, commonly known as ethanol, with the help of yeast.Thus we can locate the person whose intelligence or beauty is the average.(4) In grouped frequency distribution it can be graphically located by drawing ogives.The same energy is passed to animals when they eat them.It is considered to be as renewable source of energy because carbon dioxide and water contained inside plants and animals are released back in to the atmosphere when they are burned and we can grow more plants and crops to create biomass energy.
