A study was done to determine whether or not social exclusion causes "real pain." Researchers looked at a random sample of 7 individuals and measured brain activity in an area of the brain hat responds to physical pain to see if activity increases as distress from social exclusion increases (measured by social distress score). The social distress scores in the experiment ranged rom 0 to 10. A scatterplot shows a moderately strong linear relationship. The least squares regression line is has a slope of 0.06078 and an intercept of -0.1261. A person has a social distress score of 2.0 and a brain activity level of 0.15. What is their residual? -0.00454 a. -0.15454 Ob. 0.14546 Oc. 0.15000 Od. 0.15454 O e. Screenshot
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 predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
