A graduate student in education has developed an mathematical intervention program for under-performing school children. To test the effectiveness of his intervention he administers a math skills assessment at the beginning of the school year to a sample of n-25 students. He then implements the program throughout the year and re-assess the students again at the end of the school year. On average there was a 3 point difference between time 1 and time 2, with a variance value of...
The answers are marked but I need them explained. A new program designed to improve high school student reading comprehension has been launched in a major school district.
