A researcher does a study looking at an intervention designed to increase interest in Science among Girls. She assigns 30 girls to the intervention and 30 girls to a no intervention group. In this study, she studies only girls. Girls in this study represent:
Multiple Choice
A researcher is interested in the effects of teaching students problem-solving strategies on their abilities to solve complex mathematics problems. She randomly assigns students to either learn the strategies, or participate in a control group. She then compares their performance on a complex problem-solving task. The student performance scores on the complex problem task are the:
Multiple Choice
A researcher is interested in the effects of a YouTube video on student learning of a topic in statistics (e.g., how to calculate a correlation coefficient). He randomly assigns 50 students to one of two conditions. In one condition, the students read a traditional text. In the second condition, students view a YouTube video. He measures their performance on a post-test. In this scenario, type of instruction (text versus video) serves as the:
Multiple Choice
A researcher carries out a study examining the effects of a new science program on scores on a standardized science test. He chooses two seventh-grade classes to carry out the study. After the study is done, he finds that group who received the new program performed better than the control group. He also discovers, however, that the group he chose to receive the new program had better prior science achievement. In this study, the prior science achievement is:
