When you first plot the histogram with the limited data I think the 2 should have a column shouldnt it?
When you plotted the Box and Whisker chart you did this against the more detailed data but used the IQR from the limited data.
May be the more detailed had the same IQR but looking at the data I’m not so sure?
Good spot @EddieRocks, you’re absolutely right that the histogram for the smaller dataset is missing a column. It looks like I forgot to draw that line in, so I’ll get it amended as soon as I can.
When it comes to the larger dataset, this should have the same quartile values as the limited dataset. I remember intentionally making it that way so we didn’t have to go over calculating them again
