We have to compare the interpretability of the different types of plots.
To do this we need persons who estimate which numbers we have plotted. In
plots 1 and 2 you have to estimate how high the bars are. As an
orientation we gave you the total number of all bars together in plot 1
which is 25, so that means 25 is divided into the 4 bars and you have to
estimate which bar is which number. The higher the bar, the higher the
number; in plot 2 we didn't give you the total number but we told you that
zhe first bar represents the "1" so it's exacly 1 high and with
this knowledge you shall estimate the other bars.
In plots 3 and 4 you have to estimate which number is represented by the
dots. As a help you have in plot 3 the scale or little lines on the left
which shall help you to estimate the numbers.
In plot 4 you have the lightgrey lines as an orientation. The lightgrey
lines are at numbers 0, 5, 10,... so every 5.
In plots 5 and 6 you have to estimate which numbers are represented by the
5 parts of the pies. For this we gave you again the total number of all
parts together. In plot 5 the total number is 40, so all 5 parts of the
pie added together is 40. In plot 6 it is 100.
In plot 7 the total number is 36. In this plot it is that the darker the
colour of the circle is, the higher is the number.
