    Answer:

    Step-by-step explanation:

    1.)1,2,3,4,5

    mean=sum of all values/number of values

             =1+2+3+4+5/5

             =15/5

    mean=3

    Mode :

    In the given data, no observation occurs more than once.

    Hence the mode of the observations does not exist, means mode=0.

    Median

    1,2,3,4,5

    Middle value is 3 so the median is 3.

    2.)2,3,4,5,6,6

    mean=sum of all values/number of values

             =2+3+4+5+6+6/6

             =26/6

    mean =4.33

    Mode

          is that value of the observation which occurs maximum number of times so here mode is 6.

    Median

    2,3,4,5,6,6

     4+5/2

    9/2

    median=4.5

    3.)6,7,5,4,5,6,2,5

    mean=sum of all values/number of values

             =6+7+5+4+5+6+2+5/8

            =40/8

    mean =5

    Mode

    is that value of the observation which occurs maximum number of times so here mode is 5

    Median

    2,4,5,5,5,6,6,7

    5+5/2

    10/2

    median=5
