The marks of 5 students in a unit test are given below:-
$x – 1, 2x +1, 2x – 2, x – 1, 2x + 3$ where $x = 5$.
On the basis of above information answer the questions.
The mode of data in numerals is
Answer & explanation
Correct answer: option 3
A mode is defined as the value that has a higher frequency in a given set of values. It is the value that appears the most number of times.
ATQ,
x – 1, 2x +1, 2x – 2, x – 1, 2x + 3
Marks of 5 students is, where x = 5:
(5 - 1), (10 + 1), (10 - 2), (5 - 1), (10 + 3)
⇒ 4, 11, 8, 4, 13
Arrange the data in ascending order: 4, 4, 8, 11, 13
Now, we can see the number 4 is two times (most number of times) appears in the series.
Hence,
Mode = 4
