    Answer:

    The five most important sample values are sample minimum, sample maximum, median, lower quartile, and upper quartile.

    Min=−10

    Max=25

    M=7.5

    Q1=−10

    Q3=25

    Step-by-step explanation:

    The five-number summary is a descriptive statistic that provides information about a set of observations. It consists of the following statistics:

    1. Minimum (Min) – the smallest observation

    2. Maximum (Max) – the largest observation

    3. Median M – the middle term

    4. First Quartile Q1 – the middle term of values below the median

    5. Third Quartile Q3 – the middle term of values above the median

    Arrange the terms in ascending order.

    −10,25

    The minimum value is the smallest value in the arranged data set.

    −10

    The maximum value is the largest value in the arranged data set.

    25

    Find the median.

    7.5

    The lower half of data is the set below the median.

    −10

    The upper half of data is the set above the median.

    25
