Is there an association between blood pressure and use of metoprolol?
The following distribution of blood types in Brazil: O (45%), A (42%), B (10%), and AB (3%). What is the probability (within 0.1%) of choosing two random Brazilian blood donors and both having type O blood?
What is 20.3%.
When looking for multiple probabilities, you need to consider whether these are independent or dependent events. Since the population of Brazil is so large, this scenario essentially involves independent probability since choosing Person #1 does not significantly affect the second choice. P(A and B) = P(A) times P(B) so P(Type O and Type O) = .45 x .45 = .2025.
Whether UAB students have received their COVID vaccine.
What is a categorical nominal variable?.
What term is used in statistics to describe a difference between two observations that is large enough to be considered a 'real' difference (as opposed to one generated by chance) and how is this set?
What is significant.
Analysts set a level of 'confidence' above which they are convinced that a difference is actual, based on the statistics they are using, known as a 'significant difference'. The level of confidence will depend on the type of data being looked at.
K-pop took the international music scene by storm back in 2010 with their signature band BTS. What does BTS stand for?
What is Bulletproof Boy Scouts.
What is multiple regression.
The belief that the probability for an outcome after a series of outcomes is not the same as the probability for a single outcome.
What is gambler's fallacy.
Patient satisfaction?
What is a categorical ordinal variable.
What is the leading cause of death in low-income countries?
What is pneumonia and other lower respiratory infections.
Which female musician’s shaved head photo sold for $500,000 in 2007?
Who is Brittney Spears.
Is there an association between average monthly revenue and primary care units at UAB?
What is an ANOVA
Suppose E and F are mutually exclusive events in a sample space S with probabilities .4 and .3 respectively. What is the probability of their union?
What is 0.7
Mutually exclusive events are events whose intersection is the empty set. So the probability of their union is just the sum of their probabilities, which is .7.
The primary reason for attending UAB for the MSHA or PhD degree?
What is a categorical nominal variable.
Conditions in the places where people live, learn, work, and play that affect a wide range of health and quality-of life-risks and outcomes.
What are social determinants of health.
She is well recognized as a member of the Fugees and for her critically acclaimed debut album, which is one of the best-selling albums of all time. She also has won a bunch of awards including eight Grammys. What's her name?
Who is Lauryn Hill.
Is my grade associated with the number of hours I studied?
What is correlation.
A card is selected at random from a standard 52 card deck. Assuming all cards are equally likely to be selected, what is the probability that a red card or a king was selected?
What is 7/13
Of the 52 cards in the deck, 26 are red, 4 are kings, and 2 are red kings. Hence the number of cards that are red or are a king are 26 + 4 - 2 = 28. We subtract 2 since the 2 red kings are being counted twice. So the probability that a red card or a king was selected is 28/52 = 7/13.
Patient ID?
What is a categorical nominal variable.
Two words you'll hear quite often in statistics are 'incidence' and 'prevalence'. Are they different words for the same concept?
What is no.
Incidence is the measure of a particular phenomenon (e.g. a disease) over a particular time period. For example, the number of people diagnosed with diabetes in a given year. Prevalence, on the other hand, is the measure of a phenomenon at any given time. Again using the diabetes example, that would be the total number of people who have diabetes at a given time.
B-Real, DJ Muggs, Sen Dog, and Eric Bobo are the four main members of what '90s group, whose best-selling song is "Insane in the Brain"?
Shoot. The MSHA class came down with COVID. Is there an association between going to Zydeco last weekend and getting COVID?
What is chi-square.
In a ten question multiple choice (4 options) quiz on Dr. Hearld's final exam, you have a chance of roughly 0.0000954% to get all ten questions right guessing at random. How is this number calculated?
What is (1/4)^10.
The chance of getting each question right is 1/4, or 0.25. You multiply these probabilities together to get the probability of getting all of them right: 1/4 * 1/4 * ... * 1/4 = (1/4)^10 = 1/1048576 = 0.000000954 = 0.0000954%
Percent of diabetics at UAB having controlled HbA1c?
