Can months be independent variable?
The months do not change as a function of mass. That would be like saying, “When Chloe is 75kg it must be the 4th month.” One variable changes in relation to another. The independent variable is the one you either control or you already know how it changes.
What happens when the independent variable increases?
In an inverse or negative relationship, the values of the variables change in opposite directions. That is, if the independent variable increases in value, the dependent variable decreases; if the independent variable decreases in value, the dependent variable increases.
How to think of independent and dependent variables?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what youchange, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
When does an independent variable cause an effect?
If you write out the variables in a sentence that shows cause and effect, the independent variable causes the effect on the dependent variable. If you have the variables in the wrong order, the sentence won’t make sense. Independent variable causes an effect on the dependent variable.
What does it mean to have multiple independent variables?
But including multiple independent variables also allows the researcher to answer questions about whether the effect of one independent variable depends on the level of another. This is referred to as an interaction between the independent variables.
Why are there so many independent variables in an experiment?
The Effects of Reduced Food Size and Package Size on the Consumption Behaviour of Restrained and Unrestrained Eaters Just as including multiple dependent variables in the same experiment allows one to answer more research questions, so too does including multiple independent variables in the same experiment.
