median grade 7 is 9
median grade 5 is 8
Thus, the difference in medians is given by
[tex]9-8=1[/tex]then,
Q1 grade 7 is 6.5
Q3 grade 7 is 9.5
thus her interquatile range is given by
[tex]Q3-Q1=9.5-6.5=3[/tex]therefore, the difference of the medians as a multiple of IQR is
[tex]difference=\frac{1}{3}[/tex]answer: 1/3 for grade 7
grade 5
Q1 is 7
Q3 is 9
thus her interquatile range is given by
[tex]9-7=2[/tex]therefore, the difference of the medians as a multiple of IQR is
[tex]\text{difference}=\frac{1}{2}[/tex]answer: 1/2 for grade 5
