- What is the population?
- What is the sample?
- Is this a judgment sample or a probability sample?
- The population of the study is all full-time workers in the United States.
- The sample is the 600 workers who participated in the survey conducted by Penn Schoen & Berland Associates.
- The type of sampling used is not specified in the provided data.
Population and Sample in the Study
The population in this study refers to all full-time workers in the United States. This means that the researchers were interested in understanding the behaviors and attitudes of this group of workers specifically.
The sample, on the other hand, represents a subset of the population. In this case, the sample consists of the 600 full-time workers who participated in the survey. These individuals were chosen to provide insights into the overall population of full-time workers in the United States.
Type of Sampling
The data does not specify whether the sampling method used in the study was a judgment sample or a probability sample. A judgment sample is selected based on the researcher's discretion and may not be representative of the population, while a probability sample is chosen using a known probability method and aims to be representative of the population.
Without knowing the sampling method used, it is difficult to determine the representativeness of the sample and the generalizability of the study's findings to the larger population of full-time workers.
