While designing her next research project, Dr. Petrov decided to use a mixed-methods study design. Which of the following justifications would she be most likely to give if someone asked her about this preference? a. "I can study my variables in a way that combines multiple different perspectives and minimizes the bias of any single design type." b. "I want to maximize the external validity of my study, so I don't want to cause too much interference by using only a single method." c. "I can finish my data collection earlier by taking advantage of many different data sources; and can therefore get my research out to the public sooner." d. "This will allow me to make sure that every variable in my study is assessed at the most appropriate unit of analysis." A management researcher wants to examine whether organizations that allow their employees to work from home also report higher financial performance. The researcher is specifically interested in exploring how the relationship between work-from-home policies and financial performance operates "naturally," and wants to avoid using any contrived scenarios that may not generalize. Which of the following research designs would be the most appropriate for this research question? a. Content analysis study b. Experimental study c. Randomized contrived study d. Field study Clear my choice Seth is refreshing his research methods and analytics knowledge to prepare for a job interview. What are the main characteristics of "big data" that he should remember? Select one: a. Volume, variety, and velocity b. Reliability, validity, and fairness c. Validated, viable, and virtual d. Ethnographic, qualitative, and immersive e. Constant, clever, and cohesive Clear my choice Craig, a senior honours student, presents the following research hypothesis to his faculty advisor: "The adoption of commission-based pay systems will predict employees' retention." Why would Craig's advisor likely have concerns about this hypothesis? a. It is double-barreled b. It is not logically consistent c. It is inconsistent with prediction theory d. It lacks directionality
