# Reading bar graphs: Harry Potter

Sal interprets a bar graph. Created by Sal Khan.

• Aren't points usually given in 5s, 10s, 20, and 50s?
• Usually yes, but there's always an exception to everything.
• When Sal said "Huffenpuff", I felt that.
• 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.
• The first class of the day must have been potions class with Professor Snape.
• 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.
• 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
