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.
In a mathematical equation or model, the dependent variable is the variable whose value is to be determined by that equation or model. In an experiment, it is the variable whose behavior under controlled conditions (that are allowed to change in an organized manner) is studied.
