What are you looking for?

Syllabus

i want a project on consumer awareness in statistics.

school during 2005-06, 720 are Hindus, 628 are boys, 440 are science students. The number of Hindu boys is 392, that of boys studying science is 205 and that of Hindu students studying science is 262; finally, the number of science students among the Hindu boys was 148. Tabulate the

information.

How many Public sector banks are in India? Name Please?

i need to make a project on Changing prices of vegetables in the market for which i need to prepare a questionaire.

please suggest me some sample questions for the same

Statistical calculations in classified data are based on

(a) the actual values of observations

(b) the upper class limits

(c) the lower class limits

(d) the class midpoints

Discuss the different methods of classification of data.

Under Exclusive method,

(a) the upper class limit of a class is excluded in the class interval

(b) the upper class limit of a class is included in the class interval

(c) the lower class limit of a class is excluded in the class interval

(d) the lower class limit of a class is included in the class interval

How many classes should we have? How does one decide about the size of class interval?

What is ‘loss of information’ in classified data?

n a sample study. about the coffee habits in two towns, following information were received

Town A: males were 70%, total cofee drinkers were 40% and female non cofee drinkers wre 10%

Town B: female were 35%, male non coffee drinkers were 30% and female coffee drinkers were 20%.

out the above data in a tabular form.

The frequency distribution of two variables is known as

(a) Univariate Distribution

(b) Bivariate Distribution

(c) Multivariate Distribution

(d) None of the above

distinguish b/w spatial and chronological classification.(3 marks)

Present the following information in a suitable table:

In 2002 out of a total of 1750 workers of a factory, 1200 workers were members of a trade union. The number of women employed was 200, of which 175 did not belong to a trade union. In 2005, the number of union workers increased to 1580 of which 1290 were men. on the other hand, the number of non-union workers fell down to 208 of which 180 were men. In 2006, there were on the pay rolls of factory, 1850 workers of which 1800 belong to a trade union. Of all the employees in 2006, 300 were women of whom only 8 did not belong to a trade union.

Do you agree that classified data is better than raw data?

classify the following data by taking class intervals such that their mid-values are 17,22,27,32 and so on:

30, 30, 36, 33, 42, 27, 22, 41, 42, 30, 30, 21, 54, 36 ,31, 16, 40, 28, 19, 17, 48, 28,48, 36, 14, 37, 16, 37, 17, 54, 42, 41, 51, 44, 32, 46, 42, 31, 21, 47, 25, 36, 22, 52, 41, 40, 40, 53.

What is the difference between universe and sample?

Distinguish between census and sample surveys. list four important types of sampling methods. explain the reason for preparing sample surveys in the collection of statistics

Distinguish between Univariate and Bivariate frequency distribution.

what is frequency array??

Explain the ‘exclusive’ and ‘inclusive’ methods used in classification of data.

Can there be any advantage in classifying things? Explain with an example from your daily life.

Prepare a frequency distribution by inclusive method taking class interval of 7 from the following data:

What is the importance of statistics in modern economic set up? explain giving examples.

prepare a frequency distribution for the following data:

115, 159 ,156 ,209, 212 ,223 ,256 ,271, 310, 129, 335, 169, 184, 234, 245, 241, 265, 144, 135, 172, 173 ,229, 220, 238, 278, 243, 220, 238, 238, 298

urgent..!!! correct answers pleaz..!!

how will you choose the wants to be satisfied

Students of class XI obtained following marks in economics.- 15, 15, 18, 16, 20, 21, 25, 25, 16, 18, 22, 24, 25, 20, 18, 22, 24, 24, 25, 23, 20, 15, 16, 17, 19, 18, 22, 22.

classify the data in the form of individual series, discrete series, continuious series and cumulative frequency series.

difference between discrete and

continuous variable

in the following statement , take the no. of letters in a word as items and no. of times a word 9or same size) repeats itself as frequencies . prepare a discrete series.

"Success in the examination confers no absolute right to appointment unless government is satisfied after such an enquiry as may be considered necessary thet the candidate is suitable in all respects for appointment."

Range is the

(a) difference between the largest and the smallest observations

(b) difference between the smallest and the largest observations

(c) average of the largest and the smallest observations

(d) ratio of the largest to the smallest observation

in examination 25 students secured marks

23 28 30 32 35 36 40 41 43 44 45 45 48

49 52 53 54 56 56 58 61 62 65 68 arrange these data in form of frequency distribution usingclass as intervals

20-29 30-39 40-49 50-59 60-69 aarange the data in cumulative frequency

I have a doubt please answer the question

Mention two series from the point of view of their vonstruction. Give examples of each.
