Correct Answer - Option 1 : Only (1) and (2)

The correct answer is Only (1) and (2).

  • The mode is the most frequently occurring observation or value.
    • The mode can be computed by the histogram. Hence, statement 1 is correct.
  • The median is the middle value in the list of numbers.
    • Median will be changed if data's are changed. Hence, statement 2 is correct. 
  • The variance is a measure of variability and is calculated by taking the average of squared deviations from the mean.
    • The variance depends on the change of scale. Hence, statement 3 is not correct.
