4. I wish to know if my dogs' weights can be used to determine the speed that they can run. The weights are all measured in kilograms and the speeds in miles per hour. The following table lists the stats of ten greyhounds: Weight (kg) Speed (mi/hr) 44.4 44.3 44.8 44 The exponential regression line predicting the dog's speed, y, from the dog's weight, x, was calculated to be y = weighs 35 kg. 29 30 29.4 29.3 29.9 30.2 30.1 29.7 32 31.5 44.6 45 44.2 44.8 45.2 45.1 36.636(1.0066)*. Use this equation to predict the speed for a dog who A. 44.5 mi/hr B. 46.1 mi/hr C. 44.7 mi/hr D. 43.6 mi/hr
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.
