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.
