Direct
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
Cause and effect
Graphs showing the relationship (or not) between two independent variables.
A graph shows a proportional relationship if it is a straight line that passes through the origin (0,0). This indicates that as one variable increases, the other variable increases at a constant rate. Additionally, the ratio of the two variables remains constant throughout the graph. If the line is not straight or does not pass through the origin, the relationship is not proportional.
linear graph between an independent and independent variable
causation
The experiment shows a direct causal relationship between the two variables, indicating that changes in one variable lead to changes in the other. This demonstrates the impact of the manipulated variable on the outcome, without interference from other variables.
that there is a relationship between the two variables. This relationship can be used to predict how changes in one variable will affect the other variable.
The experiment demonstrates a direct cause-and-effect relationship between the two variables, with no interference from other variables. This suggests that changes in the dependent variable can be attributed solely to variations in the independent variable.
No correlation.
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
Cause and effect
No. It shows changes in the response variable against changes in the explanatory (or independent) variable(s).
causation
The experiment shows a causal relationship between the two variables, where changes in one variable directly impact the other without interference from any other variables. This suggests a clear cause-and-effect relationship between the variables being studied.
The vertical axis on a graph typically represents the dependent variable or the response variable. It shows the quantity being measured or observed in relation to the independent variable on the horizontal axis.
A scatter plot is a type of graph that shows how one variable changes in response to another. It is used to identify relationships and patterns between two variables.
