Here‚ we describe estimation and hypothesis-testing procedures for the difference between two population means when the samples are dependent. In a case of two dependent samples‚ two data values—one for each sample—are collected from the same source (or element) and‚ hence‚ these are also called paired or matched samples. For example‚ we may want to make inferences about the mean weight loss for members of a health club after they have gone through an exercise program for a certain period of time

LEXICAL DEVIATION Deviation corresponds to the traditional idea of poetic license: the writer of literature is allowed in contrast to the everyday speaker to deviate from rules‚ maxims‚ or conventions. These may involve the language‚ as well as literary traditions or expectations set up by the text itself. The result is some degree of surprise in the reader‚ and his/her attention is thereby drawn to the form of the text itself (rather than to its content). Cases of neologism‚ live metaphor‚ or ungrammatical

Sampling distribution The sampling distribution is the distribution of the values of a sample statistic computed for each possible sample that could be drawn from the target population under a specified sampling plan. Because many different samples could be drawn from a population of elements‚ the sample statistics derived from any one sample will likely not equal the population parameters. As a result‚ the sampling distribution supplies an approximation of the true value’s population parameters

Trends in Stock Prices and Range to Standard Deviation Ratio The Hurst was proposed in 1951 by Hurst. “The Hurst exponent provides a measure for long-term memory and predictability of a time series.”(Mitra 2011) The Hurst exponent was used in hydrological studies‚ however in 1991 and 1994 Peters used the Hurst exponent in financial studies. This article studies the Hurst exponent by developing insight on the price movements in financial markets by taking the Hurst exponent and returns in the

help visualize the possibilities.) The law of independent assortment says that an organisms individual traits are passed in independently of one another. Mendel observed that ratios were not always exact but he did not put aside these deviations. The tendency of the loci on the same chromosome to remain linked together during meiosis and gametogenesis is referred to as linkage. Autosomal linkage : the loci are on the same chromosome‚ affecting the phenotypic and genotypic ratios

The main factors that affect distribution of population are natural resources‚ climatic conditions‚ soils‚ cultural factors‚ age of human settlement‚ industrial development and means of transport and communication. The factors affecting distribution of population are described below one by one in a nutshell manner.
