In the context of this exercise, can our choice of bin size effect the appearance of a distribution?
Yes, the choice of bin size will have an effect on the visualization of the data, which can also change how the distribution itself might be interpreted, although it will have no effect on the data itself.
For example, if you changed the bin size for the histograms to something very small, say
bins=2, the bars shown will probably not provide us much information about the data distribution. This would also make it hard to determine the correct distribution shapes.
So, it is important to choose a good bin size that will show the distribution well.
