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 several laboratory investigations you do this year, a primary purpose will be to find the. mathematical relationship between two variables. For example, you might want to know the. relationship between the pressure exerted by a gas and its temperature. In one experiment you do, you will be asked to determine the relationship between the volume of a confined gas and the. pressure it exerts.
