1920s and 1930s, Hawthorne Works was the site of some well-known industrial studies. In one of the studies, researchers investigated the impact of different working conditions on worker productivity. Prior to the start of the study, researchers secretly measured workers' productivity for several weeks. Then researchers chose two workers, who then chose their own teams. The teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. Over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). For each of these changes in working conditions, the researchers measured the effect on productivity. For some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity. Why did the researchers secretly measure the workers' productivity before creating the two treatment groups? To create similar treatment groups so that a cause-and-effect relationship could be established To provide a baseline for measuring worker productivity To directly control for confounding variables

Chapter 15: "What Is Freedom?": Reconstruction, 1865-1877 15.3. What were the social and political effects of Radical Reconstruction in the South? Match the descriptions of white Republicans in the South during Reconstruction to the correct term. These northern whites relocated to the South after the Civil War. Southern whites believed they had come simply for economic gain. These southern whites supported the Republicans and had not supported secession or the Confederacy.

As part of a statistics project, Charlie would like to collect data on household size in his city. To do so, he asks each person in his statistics class for the size of their household and reports the results of a simple random sample. However, this is not a simple random sample. Why? Charlie did not use any randomization; he took a convenience sample. Charlie did not use a random number table to randomize the order in which he collected the students responses, so the sample cannot be random. In this investigation of household size, each household represents a case. Charlie incorrectly sampled individuals instead of households. Both (a) and (c) are correct. Answers (a), (b), and (c) are all correct.
