They all test relationship when it involves two variables
Explanation:
All of the statistical methods listed above all measure the relationship between two variables.
The Chi Square test tests the relationship between two nominal/categorical variable groups.
The Pearson correlation test tests relationship between two continuous variables using the Pearson correlation coefficient to determine statistical relationship between them.
The simple linear regression measures relationship between two variables: dependent/response variable and independent/explanatory variable, to see if a relationship exists between by way of influence of the independent variable on the dependent variable.
Hello there!
For questions like these, I always like to translate the figure in my head or on paper so I can get a visual of what is going on.
Take answer A, and translate the figure in your head 1 unit to the left, and then rotate it 180 degrees counterclockwise about the origin. This happens to be the correct answer so we don't have to investigate the others.
This means the answer is A.
Remember that when you move the figure one unit left, it becomes 1 unit away from the x-axis, so the figure must STAY that way during a rotation about the origin.
I really hope this helps!
Best wishes :)
