WebCorrelation is unit free; the \(x\) and \(y\) variables do NOT need to be on the same scale (e.g., it is possible to compute the correlation between height in centimeters and weight in pounds) It does not matter which variable you label as \(x\) and which you label as \(y\).
WebDec 1, 2024 · It can be explained as: 1. In a simple regression analysis, the dependent variable is y. 2. Similarly, the independent variable is x. 3. Given, if the slope is positive, then the correlation will be positive. 4. The positive relation implies that if x increases then they will also increase in simple regression analysis. WebThe correlation coefficient r measures the strength of the linear association between x and y. The variable r has to be between –1 and +1. When r is positive, the x and y will tend to …
WebMar 10, 2024 · Answer: y, x are variables b₀ and b₁ are constants Step-by-step explanation: If y=b₀+b₁x where x and y are variables. The variable y is the sum of a constant b₀ and varies directly with variable x where b₁ is the constant of proportionality of x with y. The higher the value of x, the higher the value of y. WebJan 22, 2024 · (1) A scatterplot allows you to identify outliers that are impacting the correlation. One extreme outlier can dramatically change a Pearson correlation coefficient.
