Which r-value represents the weakest correlation -0.75 , -0.27 , 0.11 , 0.54

Question:- Which r-value represents the weakest correlation -0.75 , -0.27 , 0.11 , 0.54

Answer: The correct option is 0.11.

In correlation analysis, the R-value (or correlation coefficient) is always between -1 and +1 and they tell the strength of the linear relationship between two variables including direction. It needs to be pointed out that the range of correlation values differs in the context of other statistical methods, such as regression analysis: the closer the absolute value of r is to 1, the higher the correlation. This means that a value of zero means that your data set does not contain any linear relationship at all. In this set of options, there is 0. 11 as a value is closer to zero and this value also represents the weakest level of correlation. Thus, the positive sign shows that the two variables have a very slight positive association, which by the closeness of the value to zero suggests that the two are independent of one another. In contrast, -0. 75 and 0. 54 have been established to present moderate negative and positive associations in their measures respectively. 27 means that the correlation is rather weak and negative yet stronger than 0. 11.
