Children are exposed to many colours in their environment Some babies show a striking preference for just one colour, while others will like a few colours. But these particular findings are only preliminary, on about 30 babies aged between four and nine months. We are collecting more data, she said.
Linear regression attempts to model the relationship between two variables by fitting a linear equation to observed data. One variable is considered to be an explanatory variable, and the other is considered to be a dependent variable.
Once a graph is constructed, it will be clear how much, and if, the independent variable influences the other. Not all equations and graphs are two-dimensional. In an experiment with two independent variables, which are usually designated as x and y, the dependent variable is usually z. The z-axis is the third dimension that typically represents depth or height.
