1. If the mode of the data set 16, 15, 17, 16, 15, x, 19, 17, 14 is 15, then the value of x will be 15.

2. If the mode of the data set 16, 15, 17, 16, 15, x, 19, 17, 14 is 15, then the value of x is—

(a) 15 (b) 16 (c) 17 (d) 19

3. If the mode of the data set 16, 15, 17, 16, 15, x, 19, 17, 14 is 15, then the value of x is—

(a) 15 (b) 16 (c) 17 (d) 19

4. If 16, 15, 17, 16, 15, x, 19, 17, 14 have a mode of 15, then the value of x is-

(a) 15 (b) 16 (c) 17 (d) 19

5. If the mode of the data set 16, 15, 17, 16, 15, x, 19 is 15, then the value of \(x\) is _____

6. Translate the following and find the mode of the data:
15, 11, 10, 8, 15, 18, 17, 15, 10, 19, 10, 11, 10, 8, 19, 15, 10, 18, 15, 3, 16, 14, 17, 2
Mode = 15 (since it appears most frequently)
