What is the true slope?
What 2 approaches are there to test the uncertainty around the true slope?
Range of values around the slope with a given probability of including the true slope.
What does a 95% confidence interval say about the true slope?
What is the amount of uncertainty estimated by?
True/False: The null hypothesis is the proposition that the true slope is one.
What does a null hypothesis imply?
(2 reasons)
What would support the null hypothesis?
What is a research hypothesis?
What criterion constitutes "infrequently by chance"? What is it referred to as?
When is a slope said to be statistically significant?
Which alpha percentage gives more leniency to a statistically significant number: 10% or 1%?
In reference to the comparison between t(calc) and t(table), when is a slope significant?
Correct positive
Power
Correct negative
False positive
A false positive is often called a Type One Error. What is the probability of making a type one error equal to?
False negative
A false negative decision is called a Type Two Error. What is it equal to?
True/False: The steeper the slope, the weaker the effect of the independent variable.
True/False: The effect of an independent variable is not a function of sample size.
Other things equal, how does a larger sample size affect the t ratio and probability?
Give an example showing that the effect of an independent variable is not a function of sample size.
