Normal Distribution
The normal distribution is a continuous distribution whose graph is a symmetric bell-shaped curve, centred on its mean , with spread set by the standard deviation . Many natural measurements, such as heights, follow it approximately.
The total area under the curve equals one, representing all probability.

Where it appears in Add Math
You meet Normal Distribution in the Probability Distribution chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.
Our teachers make sure a student can not only recite what Normal Distribution means but use it fluently in a full solution.
The term in three languages
Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Normal Distribution (EN) · Taburan Normal (BM) · 正态分布 (中文)
