Do you "Measure"up?
This measure of frequency is used when talking about EXISTING cases in a population
What is PREVALENCE?
In this type of study, the investigator assigns the exposure, but not at random
What is a quasi-experimental study?
Which hypothesis aligns with the research question
What is the alternate hypothesis?
I'm interested in comparing whether women who have access to care have a more favorable breast cancer survival (YES/NO) compared to women who do not have access to care. Which test do I use?
What is a test of proportions (or chi squared)?
Type of experimental group-level study where the exposure is randomly assigned
What is a community trial?
This measure of frequency is used when referring to NEW cases in a population
What is INCIDENCE?
This is a type of study where participants are followed up over time to ascertain the occurrence of disease
What is a prospective cohort study?
If you fail to reject your null hypothesis, what does this mean about significant differences
I'm interested in whether the mean BMI of school children exposed to an environmental contaminant is different from that in the general population
What is a one-sample t-test?
Type of study where exposure is observed
What is observational?
This measure of association is used for cohort studies
What is the incidence proportion ratio?
This is one of the measures used in an experimental study
What is Incidence Proportion Ratio or Incidence proportion difference?
Which of the followi
ng is not a formal part of hypothesis testing:
a. State the null hypothesis
b. Calculate a level of significance
c. Calculate the test statistic
d. Identify a critical value
What is b?
I use this test for testing mean differences when the population standard deviation is known.
What is a z-test?
Level of study where exposure is assigned (not randomly) to a group
What is community intervention?
This measure of disease frequency is used in cross-sectional studies
What is Prevalence?
In this type of study (NEED NAME), the exposure and outcome are measured at the same time
What is a cross-sectional study?
In hypothesis testing, what do we refer to as the probability of observing the result or one more extreme if the null hypothesis were true?
What is the p-value?
I'm interested in whether children exposed to air pollution in the CA central valley have a higher risk of asthma compared to children living on the northern CA peninsula
What is a test of proportion?
In this type of experimental study, both participants and investigators do not know the exposure status of the participants
What is a double-blind experimental study?
One of the measures of association used in cohort studies
What is the incidence proportion ratio or incidence proportion difference?
In this type of study, exposures and outcomes are assessed using group-level measures
What is an ecological study?
In hypothesis testing, what is the probability of rejecting the null hypothesis if the null were true usually called?
What is alpha?
What type of analysis tells me whether I have enough participants in my sample to detect significant differences?
What is a power analysis?
In this type of study, the outcome is already known at the time the exposure is assessed.
What is a retrospective (cohort) study?
