Science > Biology > Human Population and Population Control > Population Explosion Population Explosion refers to the sudden, drastic, and rapid rise in the size of the population, especially the human population. It is an unchecked growth of human population caused as a result of increased birth rate, decreased infant mortality rate, and improved life expectancy. It […]
Science > Biology > Human Population and Population Control > Demographic Study The word ‘Demography’ is a combination of two Greek words, ‘Demos’ meaning people and ‘Graphy’ meaning science. Thus demography is the science of people. Demography is the statistical and mathematical study of the size, composition, and spatial distribution of human populations and how […]
Science > Biology > Human Population and Population Control > Attributes of Human Population Part – III Population fluctuations, biotic potential, and carrying capacity is another set of attributes of the human population. Population Fluctuation: In all populations, numbers rise and fall over time. Once the population has reached equilibrium in a certain region, its […]
Management > Managerial Statistics > Index Number By Fisher’s Method Laspeyre’s method is based on fixed weights of the base year. For price index base year’s quantities are used as weights. Paasche’s method is based on fixed weights of the current year. For price index, current year’s quantities are used as weights. Fisher has suggested […]
Science > Biology > Human Population and Population Control > Attributes of Human Population Part – II Population growth is the increase in the number of individuals in a population. The growth rate is the number of individuals added per thousand individuals in a given time. The growth rate can be represented by a graph called […]
Science > Biology > Human Population and Population Control > Attributes of Human Population Part – I Group of individuals of the same species occupying a particular geographic area at a given time and have the capability to breed with each other. The population is a taxonomic category lower than the species. Population share a common […]
Management > Managerial Statistics > Index Number By Dorbish and Browley’s Method Laspeyre’s method is based on fixed weights of the base year. For price index base year’s quantities are used as weights. Paasche’s method is based on fixed weights of the current year. For price index, current year’s quantities are used as weights. Dorbish […]
Management > Managerial Statistics > Index Number By Paasche’s Method Price Index Number by Paasche’s Method: Paasche’s method is based on fixed weights of the current year. For price index current year’s quantities are used as weights. Steps involved: Denote prices of the commodity in the current year as P1 and its quantity consumed in […]
Management > Managerial Statistics > Index Number By Larpeyre’s Method When all commodities are not of equal importance, we assign a weight to each commodity relative to its importance and the index number computed from these weights is called a weighted index number. For example, when calculating the price index number if the price of […]
Management > Managerial Statistics > Index Number By Simple Average of Relative Method Simple Average of Relative Method Using Arithmetic Mean: In this method, average of price relative of commodity is calculated. Steps involved Find price relative for each commodity for the current year using the formula R = (P1 / P0) × 100. Add […]
