Question

Determine the shape of histogram of the given data.
25, 75, 50, 20, 15

  1. Skewed 
  2. Symmetric  
  3. Both a and b
  4. None of the above

hintHint:

To determine the shape first find out the mean and median

The correct answer is: Skewed


    To determine shape, we need mean and median.
    text  Mean  end text equals fraction numerator 25 plus 75 plus 50 plus 20 plus 15 over denominator 5 end fraction equals 185 over 5 equals 37
    15,20,25,50,75
    text  Median  end text equals fraction numerator 5 plus 1 over denominator 2 end fraction equals 3 to the power of text rd  end text end exponent text  observation  end text equals 25
    Then the shape of histogram is skewed.
