You are conducting a study of the common cold spreading across college dorms.

Which of the following is defined as looking up every article cited by eligible articles in order to identify other articles that might be relevant but not indexed in the selected databases?
Snowballing
A confounder may make the association between an exposure variable and an outcome variable appear more or less significant than it truly is.
T
The decision to reject or fail to reject the null hypothesis is based on the likelihood that the result of a test was due to chance.
T
When writing a research proposal, the researcher should clearly connect the research idea with the goals of the sponsor.
T
What is a major limitation when using already available data?
We are limited to exploring only the topics and questions included in the original survey.
comparative statistics, what type of error occurs when a test indicates a significant difference between two or more populations even though the null hypothesis is true?
Type 1 error
The population of individuals who are eligible to participate in the research project is called the:
study population
A good research project needs to be feasible, interesting, novel, ethical, and relevant.

type 2 error
For what type of variables is it not possible to create a histogram or boxplot?
Categorical variables
Why is it important to use a representative sample?
The results of the study need to be generalizable to a greater population.
Usually, what is the goal of any single research project?
To answer one well-defined question
To assess a study's generalizability, you might ask which of the following questions? (Select TWO)
To what other populations might the results apply? How well do these findings fit with existing knowledge about the topic?
