Question

Which of the following data sets are organised?

$\begin{array}{ccccccccccc}\text{Data set 1}& 5& 7& 12& 18& 25& 28& 34& 67& 78& 98\\ \text{Data set 2}& 101& 96& 76& 69& 56& 49& 44& 35& 23& 11\\ \text{Data set 3}& 2& 8& 54& 65& 32& 11& 13& 25& 4& 33\end{array}$

• A. Sets 1 and 2
• B. Sets 2 and 3
• C. Sets 1 and 3
• D. None of the above

Answer 1

The correct option is A

Sets 1 and 2

Data set 1 is in ascending order, whereas data set 2 is in descending order. So, both of them are organized. But we can see that data set 3 is random. Hence, it is an unorganised data set.
