    Step-by-step explanation:

    90,84,100,87,92,96,88

    arrange in ascending order

    84,87,88,90,92,96,100

    First we find the median which is their middle number, median=90

    Then we find the median in the lower half,

    Lower half=84,87,88

    Median of lower half=87

    We also find the median in The upper half,

    Upper half=92,96,100

    Median of upper half=96

    Interquartile range=median in upper half - median in lower half

    Interquartile range=96-87

    Interquartile range=9
