Concept explainers

Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…
Question
100%

If a group of variables are correlated with each other, then (choose one and
explain why)
1. the reported p-values for those variables get greater than the true p-values.
2. the reported p-values for those variables get less than the true p-values.
3. the reported estimated slopes for those variables get bigger than the true values for the estimated slopes.
