Question 5

The next  questions refer to the following experiment:

A researcher studied the influence of crowding (low, medium, and high crowding) on reading comprehension between two types of third graders. Half the children randomly assigned to each crowding condition were classified as “good” and half “poor” on an assessment of verbal fluency. In the study, each child read a 750-word passage and was tested on it later.

-This study includes
