A Pearson correlation between two variables is zero but, still their values can still be related to each other.
A) TRUE
B) FALSE
Answers
The statement given in the question about Pearson correlation is option B - True.
A Pearson correlation between two states that even if zero linear correlation exists between two individual variables, even then there might exist a certain kind of correlation.
Pearsons Correlation is a great way to select a subset of a feature.
Answer:
‘A Pearson correlation between two variables is zero but, still their values can still be related to each other’ is a TRUE statement.
Explanation:
According to statistical analysis, Pearson Coefficient is defined as the linear correlation measurement between the ‘two variables’ namely X and Y. This has the value between + 1 and – 1. Here, 1 is considered to be total positive and 0 is considered to be linear negative correlation.
It is actually a ‘covariance’ of the 2 variables that can be divided by the standard deviation’s product. For example, Y = X2. These are not only associated. But here one can be a function of other and the ‘correlation’ between them is 0.
