    Mean=9.75

    Median = 9.5

    Mode = 8,9,10,12

    Range = 6

    Step-by-step explanation:

    Arrange number in ascending order;

    6,7,8,8,9,9,10,10,11,12,12,15

    Mean = sum of terms/number of terms

    = (6+7+8+8+9+9+10+10+11+12+12+15) / 12

    =117/12

    =9.75

    Median = middle number in a list; since we have two numbers we add them together and divide by 2

    = (9+10) / 2

    = 19/2

    =9.5

    Mode = 8,9,10,12 (multimodal) this is when there are more than one mode

    Range = highest number - lowest number

    =15-9

    =6
