In this function, y is the dependent variable and x is the independent variable. Variable used in an experiment or modelling can be divided into three types:  dependent variable ,  independent variable , or other.
About 70% of men have an eye dominance that matches their handedness. BUT, 30% do not. Most right handers have a dominant right eye and the bulk of southpaws a dominant left. These are the people who are well advised to shoot both eyes open (assuming that they are shooting from their strong shoulder).
In cases of crossed eyes, there is one eye that is off-focus from the object the person is trying to see. The brainâs natural tendency is to ignore the off-focus image, leaving the eye that produces it underused and weak. After time, this weakened eye may remain out of position, resulting in lazy eye.
