correlational study. A correlation is a shared relationship or connection between two or more things. A correlation can be either positive‚ negative‚ or zero. A positive correlation is when factors or variables moves directly of each other‚ meaning if one variable goes down‚ the other will as well and vice versa. A negative correlation is when factors or variables move inversely of each other‚ meaning if one variable goes up‚ then the other will go down and vice versa. When a correlation is zero‚ it means

The Spearman Correlation Coefficient remains one of the most important nonparametric measures of statistical dependence between two variables. The Spearman Correlation Coefficient facilitates the assessment of two variables using a monotonic function. This representation is only possible if the variables are perfect monotones of each other and if there are no repeated data values. This enables one to obtain a perfect Spearman correlation of either +1 or -1. The Spearman correlation coefficient nonparametric

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

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‚
