Amelia is conducting a survey among people who travel to work using the public transportation system in her city. She wants to know how much time people spend using public transportation. She selected three samples for her study. Sample 1: 12 random members of the population who drive to work Sample 2: 12 random people who use public transportation to get to work Sample 3: 12 random people who drive to work and take public transportation on alternate days Which sample is most likely to give a valid generalization? Which is least likely to give a valid generalization? The sample that is most likely to give a valid generalization is . The sample that is least likely to give a valid generalization is . NextReset
The most valid generalization will be drawn from the responses of sample 2. The least valid generalization will be drawn from the responses of sample 1.
The reason for these statements is because the study is to investigate the time taken when using public transport. In order to do this, it is beneficial to involve individuals that use public transport frequently. The more frequently, the better. Surveying individuals that do not use public transport will give inaccurate guesses rather than accurate estimates.
