Introduction
This analysis examines the effectiveness of a reading intervention program and explores
potential differences in math placement scores across school types. Two inferential statistical
tests were employed: a paired samples t-test to evaluate reading pretest and posttest performance,
, 2
and an independent samples t-test to compare math placement scores between public and private
school students. These analyses provide evidence-based insights into student achievement
outcomes and potential educational disparities.
