9. Standardized testing in schools is a common practice in many school districts. Consider the following situation: Five years ago. a school district was concerned about the math scores of students in Gr. 9 and introduced some changes in the mathematics program to help improve student achievement. At the same time. they introduced standardized testing in math for Gr. 9 students. Improvement was seen in the math scores each year over the 5 years. Is this enough data for the school board to conclude that the changes in the mathematics program are causing the improvement in student achievement as measured on the standardized test? Are there other variables that should be considered? [3 marks] 10.
