24 Suitable average for averaging the shoe sizes for children is:
A Mean
B Mode
C Median
D Geometric mean

Answer: Mode
25 Extreme scores on an examination have the following effect on the mode:
A They tend to raise it
B they tend to lower it
C They have no effect on it
D difficult to tell

Answer: They have no effect on it
26 A distribution with two modes is called:
A Unimodel
B Bimodal
C Multimodal
D Normal

Answer: Bimodal
27 For moderately skewed distribution, the value of mode is calculated as:
A 2Mean 3Median
B 3Median 2Mean
C 2Mean + Mode
D 3Median - Mode

Answer: 3Median 2Mean
28 If the values of mean, median and mode coincide in a unimodel distribution, then the distribution will be:
A Skewed to the left
B Skewed to the right
C Multimodal
D Symmetrical

Answer: Symmetrical
29 A curve that tails off to the right end is called:
A Positively skewed
B Negatively skewed
C Symmetrical
D Both (b) and (c)

Answer: Positively skewed
30 The sum of the deviations taken from mean is:
A Always equal to zero
B Some times equal to zero
C Never equal to zero
D Less than zero

Answer: Less than zero
31 If a set of data has one mode and its value is less than mean, then the distribution is called:
A Positively skewed
B Negatively skewed
C Symmetrical
D Normal

Answer: Positively skewed
32 Taking the relevant root of the product of all non-zero and positive values are called:
A Arithmetic mean
B Geometric mean
C Harmonic mean
D Combined mean

Answer: Geometric mean
33 Geometric mean is suitable when the values are given as:
A Proportions
B Ratios
C Percentage rates
D All of the above

Answer: All of the above
34 If the two observations are a = 2 and b = -2, then their geometric mean will be:
A Zero
B Infinity
C Impossible
D Negative

Answer: Impossible
35 The ratio among the number of items and the sum of reciprocals of items is called:
A Arithmetic mean
B Geometric mean
C Harmonic mean
D Mode

Answer: Harmonic mean
36 Harmonic mean gives less weightage to:
A Small values
B Large values
C Positive values
D Negative values

Answer: Large values
37 For an open-end frequency distribution, it is not possible to find:
A Arithmetic mean
B Geometric mean
C Harmonic mean
D All of the above

Answer: All of the above
38 Which pair of averages cannot be calculated when one of numbers in the series is zero?
A Geometric mean and Median
B Harmonic mean and Mode
C Simple mean and Weighted mean
D Geometric mean and Harmonic mean

Answer: Geometric mean and Harmonic mean
39 The averages are affected by change of:
A Origin
B Scale
C Both (a) and (b)
D None of the above

Answer: Both (a) and (b)
40 The geometric mean and harmonic mean of two values are. 8 and 16 respectively, then arithmetic mean of values is:
