Pearson’s Correlation Coefficient Pearson’s correlation coefficients are the most widely used method of measuring the degree of relationship between two variables. This coefficient assumes the following: That there is a linear relationship between the two variables; That the two variables are casually related which means that one of the variables is independent and the other one is dependent; and A large number of independent causes are operating in both the variables so as to produce a

3.6.2 Correlation Analysis Correlation analysis is one of the data analysis method use in quantitative research when researchers intended to examine the relationship between both variables (Research Methodology‚ n.d.). The Pearson’s Moment Correlation Coefficient (PMCC) ranges between +1 and -1.If the coefficient value is +1 and -1‚ it is an indication that the relationships between both variables are strong. A value of +1 indicate that there is a positive relationship between variables‚ means that

Before the 1950’s anxiety was mainly treated with barbiturates and meprobamate. However‚ these drugs have disadvantages linked to dependence and abuse.

Man’s Dependence on Fossil Fuels Before the occurrence of the Industrial Revolution‚ fossil fuels were considered as temporary source of energy. They were only used to compensate for the lack of firewood and charcoal supplies that were the primary energy supplier back in the day. Although the first combustible fuel used widely which remained useful for a long period of time was wood. Advancement by both technological and social demanded a source that could provide a higher energy output. These sources

Why it is difficult for researchers to isolate specific causes of child behaviour - using two of your own examples. How is the term “correlation” a solution to this problem? It is difficult for researchers to isolate specific causes of child behaviour because each child’s environmental settings and values are different from one to another. Most scientists agree that genes have some influence over general intelligence and special aptitudes in such activities as athletics‚ mathematics‚
