Q1. di is the deviation of xi from assumed mean a. If mean = \(x+\frac{\sum f_{i} d_{i}}{\sum f_{i}}\), then x is
A. class size ‘
B. number of observations
C. assumed mean
D. none of these
Ans: assumed mean
Explaination:
∵ Mean = assumed mean + \(\frac{\sum f_{i} d_{i}}{\sum f_{i}}\)
∴ x = assumed mean.

Q2. Mean of 100 items is 49. It was discovered that three items which should have been 60, 70, 80 were wrongly read as 40, 20, 50 respectively. The correct mean is
A. 48
B. 49
C. 50
D. 60
Ans: 50

 

Explaination:
Sum of 100 observations
= 100 × 49 = 4900
Correct sum
= 4900 – [40 + 20 + 50 ] + [60 + 70 + 80] = 5000
∴ Correct mean = \(\frac{5000}{100}\) = 50.

Q3. While computing mean of grouped data, we assume that the frequencies are
A. evenly distributed over all the classes
B. centred at the classmarks of the classes
C. centred at the upper limits of the classes
D. centred at the lower limits of the classes
Ans: centred at the classmarks of the classes

 

Explaination: (b) centred at the classmarks of the classes.

Q4. The abscissa of the point of intersection of the less than type and of the more than type cumulative frequency curves of a grouped data gives its
A. mean
B. median
C. mode
D. all the three above
Ans: median
Q5. Mode is the value of the variable which has:
A. maximum frequency
B. minimum frequency
C. mean frequency
D. middle most frequency ]
Ans: maximum frequency
Q6. Mode and mean of a data are 12k and 15A. Median of the data is
A. 12k
B. 14k
C. 15k
D. 16k
Ans: 14k
Explaination:
∵ Mode = 3 median – 2 mean
⇒ 12k = 3 median – 2 × 15k
⇒ 42k = 3 median
⇒ Median = 14k.

Q7. For the following frequency distribution:If the mode and the median are 12.9 and 14.44 respectively, then the mean is​
A. 15.2
B. 13
C. 16
D. 17
Ans: 15.2
Q8. While computing mean of grouped data, we assume that the frequencies are
A. evenly distributed over all the classes
B. centred at the classmarks of the classes
C. centred at the upper limits of the classes
D. centred at the lower limits of the classes
Ans: centred at the classmarks of the classes
Q9. For a symmetrical distribution, which is correct
A. Mean > Mode > Median
B. Mode = Mean+ Median/2
C. Mean < Mode < Median
D. Mean = Median = Mode
Ans: Mean = Median = Mode
Q10. The mean and the median of a distribution are 45.9 and 46 respectively. The mode will be
A. 45
B. 47
C. 48
D. 46.2
Ans: 46.2
Q11. Which of the following is true –
A. Mode = 3Median + 2Mean
B. Median = Mode  +3/2[Mean – Median]
C. Mean = Mode + 3/2[Median – Mode]
D. Median = Mode + 3/2[Median + Mode]
Ans: Mean = Mode + 3/2[Median – Mode]
Q12. The measure of central tendency which is given by the x-coordinate of the point of intersection of the 'more than' ogive and 'less than' ogive is –
A. Mean
B. Median
C. Mode
D. None of these
Ans: Median
Q13. In the given data if n = 230, l = 40, cf = 76, h = 10, f = 65, then its median is
A. 40
B. 46
C. 47
D. 48
Ans: 46
Q14. The median of first 10 prime numbers is
A. 11
B. 12
C. 13
D. none of these
Ans: 12
