Dr. McTaggart is an industrial-organizational psychologist who conducted a job satisfaction survey for Gaggle, a high-tech company in the Silicon Hills. Gaggle has 25,000 employees. Dr. McTaggart took a list of all the employee names and had a computer program generate a list of 1000 employee names using a randomizing algorithm. All 1000 employees fully completed the survey and emailed it back to Dr. McTaggert. Dr. McTaggert found that 80% of the employees are satisfied with their job. 1. What type of sampling did Dr. McTaggert use? Is this a form of probability or non-probability sampling? Random sample is being used because He is using a generator to pick the names randomly. This is a form of probability sampling because the subjects in the population get an equal opportunity to be selected. 2. Suppose that 55% of Gaggle employees are male-identified and 45% are female-identified. What type of probability sampling should Dr. McTaggert use to ensure the sample is representative of the gender breakdown of the company? 3. Are there any threats to validity in the way this study was conducted? Explain why or why not. If yes, identify the specific type of validity being threatened.
