B. 2 Mean
C. 3 Mean

7. The ——- of a class is the frequency obtained by adding the frequencies of all the classes preceding the given class.

A. added frequency
B. cumulative frequency
C. frequency polygon

8. The ———- of grouped data can be obtained graphically as the x coordinate of the point of intersection of the two ogives for the data.

A. Mean
B. Median
C. Mode

9. ———— is not a measure of central tendency of a statistical data.

B. Frequency curve
C. Frequency polygon

13. The class marks of the class 10 -20 is ————–

A. 10
B. 15
C. 20

14. If the mean and median of a data are 18 and 16 respectively their mode is ———–

A. 10
B. 12
C. 14

15. While drawing an ogive, cumulative frequencies are marked on ——– axis.

A. x axis
B. y axis
C. none of these.

ANSWERS:

1. Mid-point
2. Mean or average
3. Class mark
4. Mode
5. Mean
6. 2Mean
7. Cumulative frequency
8. Median
9. Range
10. Mean
11. Maximum frequency
12. Ogives
13. 15
Class mark = ½ (10 + 20) = 30/2 = 15
14. 12
We know that 3Median = Mode + 2 Mean
3 x 16 = Mode + 2 x 18
48 = Mode + 36
Mode = 48 – 36 = 12
15. y axis.
