**Answer:**

- Answer: (d) all the above

Explanation: The mean for a given data can be calculated using either of the following methods.

Direct method

Assumed mean method

Step deviation method

- Answer: (d) Cumulative frequency

Explanation: The cumulative frequency of a class is the frequency obtained by adding the frequencies of all the classes preceding the given class.

- Answer: (c) maximum frequent value
- Answer: (b) Mode = 3 Median – 2 Mean
- Answer: (c) zero
- Answer: (b) centered at the class marks of the classes

Explanation: In computing the mean of grouped data, the frequencies are centred at the class marks of the classes.

- Answer: (b) Median

Explanation: Since the intersection point of less than type ogive and more than ogive gives the median on the abscissa.

- Answer: (d) 0.5

Explanation: We have

30, 34, 35, 36, 37, 38, 39, 40

The data has 8 observations, so there are two middle terms, 4th and 5th term i.e. 36 and 37.

The median is the mean of both these terms.

Median = (36 + 37)/2

Median = 36.5

When 35 is removed from given data as 30, 35, 36, 37, 38, 39, 40 then the number of observations becomes 7.

Now the median is the middle most i.e 4th term which is equal to 37.

Therefore median is increased by 37 – 36.5 = 0.5

- Answer: (a) Mean
- Answer: (a) 3 Median = Mode + 2 Mean

Explanation: The empirical relationship between the three measures of central tendency is 3 Median = Mode + 2 Mean.

- Answer: (b) median

Explanation: Construction of a cumulative frequency table is useful in determining the median.

- Answer: (d) 10

Explanation: Given,

∑f_{i} = 24

∑f_{i} = x + 5 + 6 + 1 + 2 = 14 + x

24 = 14 + x

x = 24 – 14 = 10

- Answer: (b) 12.5

Explanation: Class mark = (Upper limit + Lower limit)/2

= (15 + 10)/2

= 25/2

= 12.5

- Answer: (d) 4

Explanation: Mean of AM = 10

(a + a + 3 + a + 6 + a + 9 + a + 12)/5 = 10

5a + 30 = 50

5a = 20

a = 4

- Answer: (c) 5

Explanation: Sum of natural numbers = n(n + 1)/2

Given, mean = 3n/5

Mean = sum of natural numbers/n

3n/5 = n(n + 1)/2n

3n/5 = (n + 1)/2

6n = 5n + 5

n = 5

- Answer: (c) 33/2

Explanation: For the given data, there are two middle terms, 16 and 17.

Hence, median = (16 + 17)/2 = 33/2

- Answer: (a) maximum frequency.
- Answer: (b) 14k

Explaination: ∵ Mode = 3 median – 2 mean

⇒ 12k = 3 median – 2 × 15k

⇒ 42k = 3 median

⇒ Median = 14k.

- Answer: (C) 12

Explaination: ∵ Mode = 3 median – 2 mean

⇒ 2 mean = 3 median – mode

⇒ mean = 12 (3 median – mode)

⇒ k= 12

- Answer: (a) 8

Explanation: mean = (4 + 10 + 5 + 9 + 12)/5 = 40/5 = 8
