STATISTICS-empiricism-

A presentation of Felix Mohr, Lena Knebel, Melanie Schäfer and Alice Klein Herzog- Johann Gymnasium

Definition of empiricism:

The word empirical means from experience, regarding a scientific approach which doesn‘t depend on theoretical reasons but on resonable experiences and describable/ measurable observations. It is not a final acknowledgment.

The function of a survey: gives an overview of the opinion of the

population ( profile of a society) is a copy of the prognosticated behaviour

of a society definition of the target group increase of the course of action

The effect of empirical representations to the reader: Change of mood within population Conclusion for own decision of elections Position of the parties may change Confusion of voters

Manipulation possibilities at a presentation of a survey/ statistics:

survey:o no specification who was asked

about the topico graphical inaccuracies

(percatage share is smaller than the other one, but the bar was presented bigger)

o the viewer does not know when the survey has started and ended

statistics:o enforcement and deformation of

the grapho unlabeled axes ( you only

recognize the trend)o labeling does not start with zero

(cutout of a graph)o generally no time indication
