    Answer:

    101

    Step-by-step explanation:

    The first step is to extract the data from the stem and leaf given. From the stem and leaf, the stem is 2-digits value and leaf follows.

    Here are the stems:

    11, 21, 31, 41 and 51.

    The leaves are:

    6, 2, 4, 8, 9, 0, 1, 1, 2, 3, 4, 5, 6, 7, 8, 1, 5, 8, 0, 1, 8.

    Therefore the actual data become:

    116, 212, 214, 218, 219, 310, 311, 311, 312, 313, 314, 315, 316, 317, 318,  411, 415, 418, 510, 511, 518.

    Having done this, we calculate the IQR. The IQR is known as Interquartile range which is the difference between the upper quartile and the lower quartile.

    That is,

    IQR = Q3 – Q2

    You can simply do this in R:

    #………R code

    stm = c(116, 212,214,218,219,310,311,311,312,313,314,315,316,317,318,

    411,415,418,510,511,518)

    quantile(stm)  #… this gives you the quartiles.

    IQR(stm) #.. this gives the answer directly
