Question

Help with this box plot question.
Will give medal!

Answer 1

box plots are pretty easy,

Answer 2

q1 = quartile 1 25% of the data falls within it
q3 = quartile 3 75% of the data falls within it
m = median (the point where 50% of the data falls on either side it is denoted by a line

IQR (interquratile range) = q3 - q1

Whiskers that extend from the box are calculated given the formula anything that falls outside of those whiskers is an outlier and usually appears as a star or asterisk

Answer 3

Range is simply the possible values on the y axis, domain is the values on the x-axis.

Tbh I have no idea what the x and y axis represents in this diagram so I cant really help you any further

Answer 4

You can express range as an interval for this problem

Answer 5

Okay! Thank you for helping me out this far! @Australopithecus

Answer 6

are you looking for interquartile range or just range ?

Answer 7

Just Range!

Answer 8

highest number minus lowest number = range

Answer 9

I'm having a little tough time reading the graph. Which are the the highest and lowest number?

Answer 10

I was having trouble seeing the numbers....but I think it is 32.5 - 10 = 22.5.....and these are grades ??

Answer 11

Yes you are correct! These are the percentage of grades! So would that be the range? 22.5?

Answer 12

yes...22.5 is the range.
I am not too sure about the second part.

It says that 50% of the class scored more then how many points...
50% is in the middle and is therefore the median. The median of the numbers is close to 30, so I am guessing 50% of the class scored more then 30 ??
Not 100% sure on that

Answer 13

That does make sense though! @jdoe0001 is that right?
