Stem Leaf Plot help

okay, so i have a stem leaf plot located here

It's a stem-leaf plot showing individual grades for both males and females. my homework question asks me what differences between males and females can I conclude?

I'm not sure. Female distribution seems slightly negatively skewed, resulting in higher scores, meaning the females found this test/class/whatever it is really easy compared to male. the males were had a lot more variability.

Can someone help?
The distribution for the females is close to be bell-shaped, and the distribution for the males is more like uniform. Most females are in the 70s-80s. There are quite a few males at the high and low end.
