1. Standard Deviation
Bell Curve
Simple Interest
Compound Interest
CAGR

2. The Standard Deviation is a measure of
how spread out numbers are.
Its symbol is σ (the greek letter sigma)

4. The shape of the normal distribution is
symmetric and unimodal. It is called
the bell-shaped or Gaussian distribution
after its inventor, Gauss.

5. There is a simple interpretation of σ.
68.27 % of the population fall
between μ±1σ
95.45 % of the population fall
between μ±2σ
99.73 % of the population fall
between μ±3σ

8. The year-over-year growth rate of
an investment over a specified period; c
alculated by taking the (N)th root
of the total percentage growth rate,
where (N) is the number of years in the
period being considered.
