1. A researcher predicted that students will learn better if they attribute their performance to effort rather than natural ability. In one condition, a randomly selected group of sixth graders wrote an essay about a time when they worked hard to reach a goal. In a second condition, a different randomly selected group of sixth graders wrote about a skill they thought they were naturally good at. Afterwards, the students began a nine-week social studies unit that concluded with an achievement test. Use the data below to conduct an appropriate statistical test (higher scores indicate higher achievement). Follow the 7 hypothesis testing steps you have been taught.
