    Bryce IQR = Q3 - Q1 = 98.5-81.5 = 17

    btw the notation FQ and TQ should be replaced with Q1 and Q3

    They seem to be split 50/50 in terms of who has larger scores but Bryce does have larger Q3 and max values however, in terms of consistency, brianna is more consistent since her IQR is lower

    the student I think should get the math award is Bryce because even though they are both split 50/50 for who has the higher grade he does have a higher IQR than Brianna which makes her more consistent. @jim_thompson5910

    having a larger IQR means things are more spread out which means that his grades aren't as consistent as brianna's grades the larger IQR is not a good thing. It's better to be consistent and aim for a good grade as well
