Correct Answer - Option 3 : 14, 33

**Given:**

The given data,

31, 33, 37, 31, 43, 33, 45, 34, and 33

**Concept used:**

Range of the data is the difference of the largest value and the smallest value

Mode is the most repeated value in a data

**Calculations:**

Arranging the values in ascending order

31, 31, 33, 33, 33, 34, 37, 43, 45

Smallest value = 31

Largest value = 45

Range = 45 – 31

⇒ Range = 14

The most repeated term,

Mode = 33

**∴**** The range and the mode of the given data is 14 and 33 respectively.**
