Question 3

I think the bar chart is the most informative for several reasons of all the seven presentations above. It is simple to see which values score the most at a glance (Erzin & Shenmaier, 2021). One does not need to measure variables because their length is easy to measure with an eye observation. Secondly, it allows for different colors to be used for each bar. Therefore, differentiating between bars becomes easy (Schnürer, Ritzi, Çöltekin & Sieber, 2020).
