What is false base line?

difference between table and tabulation ??????

what is the statistcial table ? explain briefly the main charactertics of a good statistical table

Bar diagram is a

(i) one-dimensional diagram

(ii) two-dimensional diagram

(iii) diagram with no dimension

(iv) none of the above

The weekly wages of 1000 workers are normally distributed around a mean of Rs.70 and a standard deviation of Rs. 5. Estimate the number of workers whose weeklywages will be:a. Between 70 and 72b. Between 69 and 72c. More than 75d. Less than 63

Explain the importance of graphic presentation.

what is the difference between classification and tabulation?

Ogives can be helpful in locating graphically the

(i) mode

(ii) mean

(iii) median

(iv) none of the above

make a diagram of the following data on population in india

year- 1951 1961 1971 1981 1991 2001 2011

population(in crore) 36.1 43.9 68.3 84.6 102.8 121.0

what are the main objectives of tabulation?

Data represented through a histogram can help in finding graphically the

(i) mean

(ii) mode

(iii) median

(iv) all the above

What kinds of diagrams are more effective in representing the following?

(i) Monthly rainfall in a year

(ii) Composition of the population of Delhi by religion

The Indian Sugar Mills Association reported that, ‘Sugar production during the first fortnight of December 2001 was about 3,87,000 tonnes, as against 3,78,000 tonnes during the same fortnight last year (2000). The off-take of sugar from factories during the first fortnight of December 2001 was 2,83,000 tonnes for internal consumption and 41,000 tonnes for exports as against 1,54,000 tonnes for internal consumption and nil for exports during the same fortnight last season.’

(i) Present the data in tabular form.

(ii) Suppose you were to present these data in diagrammatic form which

of the diagrams would you use and why?

(iii) Present these data diagrammatically.

Q.1-What Is Loss Of Information In Classified Data ???

Q.2-When do generally errors of grouping arise?

Q.3-Crop Production is discrete or continuous variable?

Q.4-Why is gender said to be a variable although it can't be numerically expressed?

Q.5-What are the various uses of bar diagrams?

why do we need to find mean mode and median ??

waht are the use of it???
