1. Fill in the blank: For these data, distances from the beach that are greater than the mean of the distances from the beach tend to be paired with house prices that are Choose one the mean of the house prices. 2. According to the regression equation, for an increase of one mile in distance from the beach, there is a corresponding decrease of how many thousand dollars in house price? 3. From the regression equation, what is the predicted house price (in thousands of dollars) when the distance (in miles) from the beach is 10.0 miles? (Round your answer to at least one decimal place.) 4. What was the observed house price (in thousands of dollars) when the distance (in miles) from the beach was 10.0 miles?
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.
