Definition:The Pearson correlation coefficient, also called Pearson’s R, is a statistical calculation of the strength of two variables’ relationships. In other words, it’s a measurement of how dependent two variables are on one another. What Does Pearson Correlation Coefficient Mean? Contents[sho...
Correlation is the degree to which the prices of assets move together. If the prices move in a similar proportion and in the same direction, they have a high correlation. If they move in opposite directions, they have a high negative correlation.
The p-value hypothesis test does not necessarily make use of a preselected confidence level at which the investor should reset the null hypothesis that the returns are equivalent. Instead, it provides a measure of how much evidence there is to reject the null hypothesis. The smaller the p-valu...
What is the value of the correlation coefficient? What does it mean to say that the linear correlation coefficient between two variables equals 1? What would the scatter diagram look like? In logistic regression with one explanatory variable, what is the P-value when the X^2test statistic has...
What does the p-value in hypothesis testing represent? Hypothesis Testing: A hypothesis can be thought of as a guess about a natural or social phenomenon that has to be falsifiable and testable. This is because after a hypothesis is developed, one must test it using empirical data. If the ...
Does not consider the subjective value consumers may pursue May detract from focusing on the aspects of a situation that do change in tandem with other variables Ceteris Paribus vs. Mutatis Mutandis While somewhat similar in assumption aspects, ceteris paribus is not to be confused withmutatis mutan...
The cross-analysis method is typically used to analyze the relationship between two variables (fields).It involves arranging two variables with a certain correlation and their values simultaneously in a table, making each variable’s value a crossing point of different variables, thus forming a cross...
What does it mean if the prime rate goes down? If the prime rate were to go down, the cost of paying interest on variable-rate loans, such as mortgages orlines of credit, would also decrease. As a result, more of each payment would go toward your loan’s principal instead of the in...

Correlation Coefficientrρ Tip:In statistics, the word parameter rarely pops up. That’s because ALL we deal with is statistics! You might see something like “population mean.” That makes it more obvious it’s about the whole parameter. When you see just “mean,” that’s usually a stat...
