1. What happened to the hump?

2. So what’s the story behind the data, and change in distribution?

3. If it doesn’t match a normal distribution, is that an indication of something going wrong?

4. I need to know what the x and y axis are!

5. From what little I know of statistics, isn’t that kind of bimodal distribution an indication of some secondary factor skewing results? Could be very wrong so please correct me if so but is seems like something must have caused that change in 2025

6. Whoa, that’s a steep curve! 📈 Looks like either the exams got tougher or everyone decided to be a grammar guru this year. Thoughts on what’s up with the spike in low scores? 🤔 #DataCrunch

7. 2 populations. Differences among graphs is bc of the different central number. In the last one, you just had both populations with the same one.
