The data set below lists the corresponding global temperature, measured in , for various concentration levels of carbon dioxide, measured in , in the atmosphere. 314 317 320 326 331 339 346 354 361 369 Temperature 13.9 14.0 13.9 14.1 14.0 14.3 14.1 14.5 14.5 14.4 d) Are higher levels causing the global temperature to also rise? e) What does the value of tell us? f) Find the regression line and sketch the line on the scatterplot. Round decimals to three places.
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.
