Perancangan Eksperimen [3] February 22, 2009

Posted by desrinda in Perancangan Eksperimen.

During the class, we were studying basic statistics terminologies. All of my classmates have enjoyed Bu Isti’s explanations, she’d great passion in teaching then we could get more understanding on terms previously learnt (Statistik Industri).

Data presentation:
– nominal (has no mean, median, etc)
– ordinal (numbers in order)
– interval
– ratio (can apply math operators)


= Data spread or diversion, consists of range + variance + standard deviation.

For continuous data, it is necessary to transform it to presented as standardized normal distribution.
