There are a number of independent variables, which, when taken together, produce a result — a dependent variable.
In practical work, it is frequent that there is power relation among independent variables when the correlation between dependent variable and independent variables is explained by regression model.
The regression model is then used to predict the result of an unknown dependent variable, given the values of the independent variables.
The house size, unfortunately, isn't an independent variable because it's related to the bedrooms variable, which makes sense, since bigger houses tend to have more bedrooms.
