A random sample shows that 48% of students prefer learning programming through games, with a margin of error of ±4% at 95% confidence.

A 4% margin of error around the sample estimate of 48% gives an interval from 48% − 4% = 44% to 48% + 4% = 52%. Thus, the result estimates that between 44% and 52% of all students prefer game-based learning; it does not mean exactly 48% do or that 95% of students prefer it.
