Aren't points usually given in 5s, 10s, 20, and 50s?

Usually yes, but there's always an exception to everything.

Dumbledore: 1000 points to Gryffindor because Harry sneezed

No, it's 1000 points to Gryffindor because Harry exists, 10000 points from Slytherin because Tom Riddle tried to kill Harry.

why is this a statistical question ?

If you take anything, and compare it against something else......you can make a comparison. If you can compare something, you can perform statistical analysis.

what is the difference between a histogram and a bar graph

Here's a website that should help you understand: http://shodor.org/interactivate/discussions/HistogramsVsBarGraph/

is a histogram and bar chart the same thing

Great question. No, because a bar is used to display a categorical data. Histograms are used to present continues data. That's the difference.

What if the bar graph for Slytherin, for example, is in between two numbers (eg. in between 4 and 5) but is closer to 5 than 4. So do we round up the value and assume 4.5?

i would think it would be considered 5 not 4.5

the point was too low, with Hermione on Gryffindor, and Harry won 50 points to be the "chosen one"(Malfoy speech) 'dunbome-dore' favorite student. Gryffindor will get 80 point every day! And that "Slytherin"(James speech) will get 30 point down.----> snape + the carrow + That Umbridge women VS professor lockhart + professor Moody (that barty crouch) + Dumbodole + slughorn = 30 point from Slytherin every day.

Video transcript

At Hogwarts, there are four houses-- Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. The bar chart below shows the number of house points that each house received today. How many house points did Hufflepuff receive? So if we look at this bar chart, we could assume that this column right over here is Hufflepuff, because it's the only one that starts with an H. This will be Gryffindor, this is Ravenclaw, and this must be Slytherin. And so, if we look at Hufflepuff's bar, it looks like they have 3 points scored today. So let's put 3 points. All right, let's try one more. So here they're saying, how many house points did Slytherin receive? So this is going to be Slytherin, and it looks like they received 4 points.
