DESCRIPTIVE STATISTICS I (101)
QUESTIONS
1. C.U. 1997:
(a) What do you mean by Skewness of a frequency distribution? Give two measures of Skewness and find the limits within which they lie.

2. C.U. 1998:
(a) Show that

can be used as measures of Skewness and Kurtosis of a frequency distribution, where
2 3 m ,m and
m4 are the second, third and fourth Central Moments.

Also prove that,
b2 b1 +1 and explain the situation under which equality holds.
(b) Write short notes on: Sheppards Correction for Moments.

3. C.U. 2002:
(a) Distinguish between:
(i) Primary Data and Secondary Data
(ii) Bar Diagram and Pie Diagram
(iii) Frequency Data and Non-frequency Data
(iv) Discrete Variable and Continuous Variable

is the logarithm of the mid-value of the first class interval, C is the logarithm of the ratio between upper and lower class boundaries of a class and ‘N is the total frequency. (d) Define Skewness and give its two measures, the first one based on the arithmetic mean and median and second one based on the three quartiles. Show that, the first measure lies between 3 and 3 and second measure lies between 1 and 1.
