Solution: 

The median of a set of numbers is simply the middle number when you arrange them in order from smallest to largest.


To find the median of the given data set: 

1,1,1,2,4,5,5,7,8,12,12,16,17


Identify the middle value:

  • Since the data set has 13 numbers, the median will be the 7th number when arranged in ascending order {because (13+1)/2= 7}


Find the median:

  • The 7th number in the sorted list is 5

Therefore, the median of the data set is 5

Importance of this question:

  • Previously asked in ADRE SLRC 2022 for the Grade-III Posts. 
  • The median identifies the middle value in a dataset, showing central tendency.
  • mportant for foundational statistics knowledge.
  • Used in various fields for data interpretation.
