edita basic introduction (not complete)

: __"sigma"__ which means __"sum of"__

example:

(considering numbers 1 to 10)

sum of numbers from **2** to **4** by factor of **1** ( )

4

**Σ** 1x_{i} = 2 + 3 + 4 **= 9**

i=2

the mean ( ) = **sum** of all scores / number of scores = **Σ**x / n

**also:**

standard deviation (§)

variance (v)(§^{2})

box plots

-quartiles

stem plots

class limits, boundaries, classmarks

transformations on data sets
