Question

In ordered series, the data are
A. In descending order
B. In ascending order
C. Either (A) or (B)
D. Neither (A) nor (B)

Answer 1

Hint: We are asked about the data in an ordered series. In an ordered series the data are in any particular order, either ascending or descending. Hence by using examples and analysing the given options we can select the correct option.

Complete step-by-step answer:
Now we need to discuss the ordered series.
An ordered series is something where the data is arranged in any particular order.
It is not compulsory that it should be only in ascending order or only in descending order. Any order is accepted.
For example, consider a series
$1 + 2 + 3 + ...$
Here we can see the data are arranged in ascending order, hence it is an ordered series.
Same way, consider a series
$80 + 79 + 78 + 77 + ...$
Here we can see the data are arranged in descending order, hence it is also an ordered series.
From this we get that in an ordered series, the data are in either ascending order or descending order.
Now let’s discuss the options given
In the first option it is given that the data are in ascending order. In an ordered series the data can be in ascending order, but it is not compulsory that it should be only in ascending order. Hence it is partially correct.
In the second option it is given that the data are in descending order. In an ordered series the data can be in descending order, but it is not compulsory that it should be only in descending order. Hence it is partially correct.
In the third option it is given that the data are either in ascending order or descending order. In an ordered series the data can be either in ascending order or descending order. Hence it is the correct option.

So, the correct answer is “Option C”.

Note: Many students tend to select the first two options, but it is not compulsory that it should be only in ascending order or only in descending order. So, the options are only partially correct. Considering the last option, that the data is not in any order then it is not an ordered series.
