Which of the following is an accurate description of the scatterplot? O The kickers have unusually low success rates when the distance is large. Field-Goal Distance and Success Rate 80 O The kickers have unusually high success rates when the distance is small. 75 O As the distance of the attempt increases, the kickers have a lower success rate for their field goals. 70 65 O As the distance of the attempt increases, the kickers tend to have a lower success rate for their field 55 goals. 50 45 40 35 20 25 30 35 40 45 50 55 60 65. 70 Success Rate (%)
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.
