True or false: scatterplots are linear?
true
True or false: in a scatterplot with positive correlation, as values for Y increase, values for X increase?
true
True or false: in a scatterplot with negative correlation, as values for y decrease, values for X increase?
true
What are assumptions of pearson correlation?
Nature of the relationship between the two variables is assumed to be linear
The two variables are assumed to have been measured using interval or ratio-scaled measures
Variables to be analyzed come from a bivariate normally distributed population
True or false: with the pearson correlation coefficient, the higher the absolute value of the correlation coefficient, the stronger the level of association?
true
If there is a statistical significance, is there a relationship between the correlated variables?
Yes
What numbers does the correlation coefficient fall between?
-1.00 and +1.00
What are the strength types in a correlation relationship?
No relationship, Weak, Moderate, Strong
What is the strength of a correlation determined by?
Determined by the size of the correlation coefficient
True or false: a larger correlation coefficient = stronger association?
true
What is the range for a strong corellation coefficient?
Positive or negative .81 to 1.00
What is the range for a moderate corellation coefficient?
Positive or negative .61 to .80
What is the range for a weak corellation coefficient?
Positive or negative .41 to .60
What is the range for a very weak corellation coefficient?
Positive or negative .21 to .40
Does a correlation coefficient of .20 or below have any correlation?
No
