There are many normal distributions such as characteristics describing people and in particular their mental characteristics such as achievement motivation, intelligence, reading comprehension, problem-solving ability and verbal aptitude. However, there are differences in these distributions that make it hard to compare data. For instance, their mean and standard deviation greatly varies. Therefore, when comparing data from different distributions, there is need to transform

Technological advancement and the need to find new drugs for effective treatment of various diseases have paved way for numerous research studies. In order to produce quality and acceptable results, researchers are strictly required to follow the necessary research procedures. For instance, researchers are required to state the hypothesis of their research and choose an effective method of testing it. Therefore, in relation to the researcher’s wish to study the effect of a ne

There are a number of statistical techniques that can be used to show relationship between variables in sets of data as covered in the course materials. One such statistical technique is the use of correlation. Correlation is indeed an important statistical test that shows how pairs of variables relate to each other. In fact, the main purpose of correlation is to show how strongly these pairs of variables relate. Therefore this paper will explore how correlation has been used

Introduction Over the years, researchers have tried to find a way of improving memory in young and growing children. Some of the well-known methods that have already proved effective include physical exercise and also eating special diets. Other than that, recent research has indicated that eating chocolate can improve memory. In fact, Jones and Wilson (2011) found that eating chocolate two hours before taking math tests improved scores significantly. Based on these expectati
