continuous
Determine if the following events are independent. Studying for a math exam. Making an A on your math exam.
dependent

discrete
Determine if the following events are independent. Chris goes out to eat for dinner. Jessica watches the evening news.
independent
Determine whether the following events are mutually exclusive. Choosing a student who is a mathematics major or a philosophy major from a nearby university to participate in a research study. (Assume that each student only has one major.)
mutually exclusive
Determine if the correlation between the two given variables is likely to be positive or negative, or if they are not likely to display a linear relationship. The temperature and the number of cases of frostbite
negative
Determine if the correlation between the two given variables is likely to be positive or negative, or if they are not likely to display a linear relationship. the number of pets owned by a family and the value of their house
no correlation
Determine whether the following events are mutually exclusive. Choosing a queen or a black card out of a standard deck of cards.
not mutually exclusive
Determine whether the following events are mutually exclusive. Choosing a student who is a sophomore or a philosophy major from a nearby university to participate in a research study.
not mutually exclusive

outcome
What is a data value, X, such that approximately (1 − P) percent of the data are greater than or equal to X?
percentile
Determine if the correlation between the two given variables is likely to be positive or negative, or if they are not likely to display a linear relationship. The number of hours you spend on homework and your GPA
positive
What is one of three points that divides a set of data into four equal parts?
quartile
Decide if the following probability is classical, relative frequency, or subjective. You guess that there is a 50% chance that you will be assigned homework in your physics class on Thursday.
subjective probability
What is useful in comparing data values from populations with different means and standard deviations?
