31. In a symmetrical distribution Q1 = 20 and median= 30. The value of Q3 is:

1. 50
2. 35
3. 40

3. Dispersion
4. Kurtosis

33. The second and fourth moments about mean are 4 and 48 respectively, then the distribution is:

1. Leptokurtic
2. Platykurtic

4. Symmetry

36. The measurements of spread or scatter of the individual values around the central point is called:

1. Measures of dispersion
2. Measures of central tendency
3. Measures of skewness

37. The measures used to calculate the variation present among the observations in the unit of the variable is called:

1. Relative measures of dispersion
2. Coefficient of skewness
3. Absolute measures of dispersion
4. Coefficient of variation

38. The measures used to calculate the variation present among the observations relative to their average is called:

1. Coefficient of kurtosis
2. Absolute measures of dispersion
3. Quartile deviation
4. Relative measures of dispersion

39. The degree to which numerical data tend to spread about an average value called:

1. Constant
2. Flatness
3. Variation
4. Skewness

40. The measures of dispersion can never be:

1. Positive
2. Zero
3. Negative
4. Equal to 2

41. If all the scores on examination cluster around the mean, the dispersion is said to be:
