reader understand about the weather?
Read the excerpt from "Seedfolks."
The sidewalk was completely empty. It was Sunday, early
in April. An icy wind teetered trash cans and turned my
cheeks to marble. In Vietnam we had no weather like that.
Here in Cleveland people call it spring. I walked half a
block, then crossed the street and reached the vacant lot.
It is spring in Cleveland.
It nearly blows over trash cans.
It is unlike the weather in Vietnam.
It is unpleasant and cold.

The authors of the paper "fudging the numbers: distributing chocolate influences student evaluations of an undergraduate course"† carried out a study to see if events unrelated to an undergraduate course could affect student evaluations. students enrolled in statistics courses taught by the same instructor participated in the study. all students attended the same lectures and one of six discussion sections that met once a week. at the end of the course, the researchers chose three of the discussion sections to be the "chocolate group." students in these three sections were offered chocolate prior to having them fill out course evaluations. students in the other three sections were not offered chocolate. the researchers concluded that "overall, students offered chocolate gave more positive evaluations than students not offered chocolate." indicate whether the study is an observational study or an experiment. give a brief explanation for your choice.
