Correlation Correlation Co-efficient Definition: A measure of the strength of linear association between two variables. Correlation will always between -1.0 and +1.0. If the correlation is positive‚ we have a positive relationship. If it is negative‚ the relationship is negative. Correlation Correlation can be easily understood as co relation. To define. correlation is the average relationship between two or more variables. When the change in one variable makes or causes a change in

variable The variable is the important aspects of the research. In research the concept are measure from variable. Variable are anythings that can take on differing or varing values. it mean that the value of variable vary from person to person‚ time to time or place to place but the meaning of variable are same to all. Thus variable are the charactestics of person‚ groups‚ objects‚ ideas‚ feeling or other thing that researcher want to measure. Variables are thus anything that can take on differing

Differences between Data Handling in Correlation & Experiment 1. Summarize entire relationship • We don’t compute a mean Y (e.g.‚ aggressive behavior) score at each X (e.g.‚ violent tv watching). We summarize the entire relationship formed by all pairs of X-Y scores. This is the major advantage

1 CORRELATION & REGRESSION 1.0 Introduction Correlation and regression are concerned with measuring the linear relationship between two variables. 1.1 Scattergram It is not a graph at all‚ it looks at first glance like a series of dots placed haphazardly on a sheet of graph paper. The purpose of scattergram is to illustrate diagrammatically any relationship between two variables. (a) If the variables are related‚ what kind of relationship it is‚ linear or nonlinear
