And your question....
It bothers me that 100 randomly selected poor readers in the 8th grade. Goodness, what was the total population of poor readers in the 8th grade? 1000?
Suppose a researcher wants to study the effectiveness of a new reading program for students who have not acquired the necessary reading skills by the time they reach the 8th grade. A randomly selected group of 50 students from a local junior high with poor reading skills will undergo a special reading program. Another group of 50 randomly selected students with poor reading skills will undergo regular reading classes. A month later, the reading skills of all 100 students are assessed to determine whether the program was successful.
