The population standard deviation σ of a discrete random variable ‚ Measure how close a random variable tends to be the population mean μ‚ so you must understand μ before you understand σ If you have a random variable like a bet at a casino or and investment then the standard deviation σ measure the risk‚ if there is a lot of risk then the standard deviation is high The formulas for standard deviation are given below but you should look at the examples first Population mean Population variance

populated country in the world though it is a small country of only 1‚ 47‚ 570 square kilometers. At present it has a population over 150 million. About 1000 people live per square kilometer here. Every year more than two million people are being added to our population. The problem has now moved out of control and it has now come to the stage of explosion. Though the population of a country is an asset‚ it becomes a problem when the country cannot afford to give its people the basic necessaries

Using Census Information in Planning In a number of countries‚ the population census plays a major role in the allocation of elected political seats in government. The number of elected officials for each governmental administrative unit is determined by the population size of a given locale. For some countries‚ the information is also used in the allocation of government resources. The size of the population determines‚ in part‚ the amount of money that is provided by government for development

Genetically Vigorous Populations Paper Megan Lade University of Phoenix (Online Campus) Niladri Sarker Introduction into Genetic Diversity Genetic diversity provides a species with its form and function. A species genotype refers to their genetic code; what their cells are going to be used for – hair cell‚ eye cell‚ muscle cell‚ etc. A species phonotype refers to the way in which that species gene will be expressed – blonde hair‚ blue eyes‚ large muscle tone; which significantly impacts
