If I a have data like a bunch of classes where each class can have a different number of students, and each student has a grade (0-100), for example like this:
tdf = pd.DataFrame({'classes':["a", "a", "a", "b", "b", "b","b","b", "c", "c"],
'grades':[78, 28, 10, 3, 79, 91, 65, 51, 75, 89]})
What is the best way to visualize the range of grades within each class? I want to show that in class A, there is a range between 10 and 78, in B there is 3 and 91, in C there is 75 and 89. I was thinking of boxplot or violin plot but when I tried them I am not really sure. Is there such thing as a bar chart that can show range? Will that make sense?
I am not sure if this is the right place to ask, so here I am.
