When two variables are related but one does not cause the other researchers term the situation?
Researchers term the situation as correlation. Correlation indicates a statistical relationship between two variables, showing how they move together but not necessarily implying causation. The strength and direction of the correlation can provide insights into the relationship between the variables.
Ths term that describes when two factors or two social phenomena co-vary with each other?
The term you are looking for is "correlation." This refers to a statistical measure that indicates the extent to which two or more variables fluctuate together. A positive correlation means the variables move in the same direction, while a negative correlation means they move in opposite directions.
When is the correlation coefficient zero?
The correlation coefficient is zero when there is no linear relationship between two variables, meaning they are not related in a linear fashion. This indicates that changes in one variable do not predict or explain changes in the other variable.
What is correlation between unemployment and divorce?
The correlation between unemployment and divorce is the ending of a job and the ending of marriage. However, that being said unemployment versus divorce is a poor example as a divorce hurts more than being unemployed.
What are the three conditions necessary for causation between variables?
The three conditions necessary for causation between variables are covariance (relationship between variables), temporal precedence (the cause must precede the effect in time), and elimination of plausible alternative explanations (other possible causes are ruled out).
The correlation between an asset's real rate of return and its risk as measured by its standard deviation is usually?
The correlation between an asset's real rate of return and its risk (as measured by its standard deviation) is usually:
What does a correlation of 0.20 means and can correlation be measured in percentage?
A correlation of 0.20 is somewhat low, meaning that the degree of linear relationship measured between the two variables involved is low. However, such a degree of relationship would not be ignored in many fields of science where relationships are difficult to detect. Correlation is rarely if ever put in terms of percentage.
Is it possible to obtain a correlation coefficient of 1.5 for two sets of test scores?
No. Correlation coefficient is measured from +1 to -1. In addition, if the two sets of exam are exactly same, their correlation coefficient is +1.
The Pearson product-moment correlation coefficient r requires that variables are measured with?
Either an Interval or an Ordinal Scale
What particular measure of correlation would be most appropriate for use with two variables measured at an ordinal?
Chi Square
What are the possible ranges of correlation coefficients?
The possible range of correlation coefficients depends on the type of correlation being measured. Here are the types for the most common correlation coefficients: Pearson Correlation Coefficient (r) Spearman's Rank Correlation Coefficient (ρ) Kendall's Rank Correlation Coefficient (τ) All of these correlation coefficients ranges from -1 to +1. In all the three cases, -1 represents negative correlation, 0 represents no correlation, and +1 represents positive correlation. It's important to note that correlation coefficients only measure the strength and direction of a linear relationship between variables. They do not capture non-linear relationships or establish causation. For better understanding of correlation analysis, you can get professional help from online platforms like SPSS-Tutor, Silverlake Consult, etc.
What particular measure of correlation would be most appropriate for use with two variables measured at an ordinal level?
Chi Square
How is a linear relationship between two variables measured in statistics?
The Correlation Coefficient computed from the sample data measures the strength and direction of a linear relationship between two variables. The symbol for the sample correlation coefficient is r. The symbol for the population correlation is p (Greek letter rho).
What is an example of correlation in statistics?
An example of correlation in statistics is the relationship between hours studied and exam scores. Typically, as the number of hours a student studies increases, their exam scores also tend to increase, indicating a positive correlation. This means that the two variables move in the same direction, though it does not imply causation. Correlation is often measured using Pearson's correlation coefficient, which quantifies the strength and direction of the relationship.
When do you use Pearson's r?
See related link. As stated in the link: In probability theory and statistics, correlation (often measured as a correlation coefficient) indicates the strength and direction of a linear relationship between two random variables
What is the correlation between two quantities?
It is a measure of the extent to which a linear change in one quantity is accompanied by a linear change in the other quantity. Note that only linear changes are measured and that there is no causality.
How many yards in a 55 gallon drum?
Yards are a unit of lineal measurement. -Drums are measured in volume, so there is no correlation here.
