Test for the Slope of the LSRL Flashcards
What’s the general hypothesis for a test for the slope of the LSRL?
Ho: B=0 There’s no linear relationship
Ha: B DOESN’T =0 There’s a (Positive/negative) linear relationship
When do you use the “Test for the Slope of the LSRL?”
It is used to test if their is a possible linear relationship.
What are the conditions and assumptions for the “Test for the Slope of the LSRL?”
- The scatterplot shows a possible linear relationship.
- For each value of X, the probability distribution of Y has the same standard deviation.
- For any given X, the Y value is independent.
- Y values are roughly normally distributed.
How do you determine degrees of freedom for a test for the Slope of the LSRL?
N-2
How do you determine expected counts for the chi squared test for the slope of the LSRL test?
You don’t. That’s not a thing. She doesn’t even go here. L33t H4ck0rz iz lyf3
what is the “test for the slope of the LSRL”’s test statistic formula?
