A school investigated the impact of a new math curriculum on student performance. The school randomly
assigned 50 students to the new curriculum group and 50 students to the
traditional curriculum group.
After a
year, the school compares test scores between the two groups.
Is this a valid experiment? Why or why not?
A. This is a valid experiment because students' initial test scores were not considered.
B. This is a valid experiment because students were randomly assigned to the two curriculum groups.
C. This is NOT a valid experiment because the sample size of 100 students is too small for meaningful
results.
D. This is NOT a valid experiment because different tests should have been used across the two
curriculum groups.
