Question

1. Find the mean, median, and mode of each set of numbers.
a) 13 kg, 71 kg, 95 kg, 62 kg, 29 kg, 25 kg, 31 kg, 40 kg

Answers

  1. Mean is 45.75

    add them up and divide by the number of numbers there are

    There is no mode

    that means most occurring

    Median is 35.5

    add them up Least to greatest the one or two in the middle take the two add them and divide by 2

  2. Answer:

    Mean = Sum of observation/Total no. of observation.

    = 326/8

    = 40.75

    To find median, we need to arrange the observation in ascending order

    = 13, 25, 29, 31, 40, 62, 71, 95.

    Now, median must be between 31 & 40.

    = 31 + 40/2

    = 35.5

    Mode = Null.
