What are you looking for?

Syllabus

i want a project on consumer awareness in statistics.

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

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.

Discuss the different methods of classification of data.

In a trip organized by a college there were 100 people; the average cost works out to 1600 per head. There were 80 students each of whom had paid 1600. Members of the teaching staff were charged a higher rate. The number of support staff (all male) was 6 and they were not charged. The number of ladies was 20% of the total of which two were lady staff members.What is ‘loss of information’ in classified data?

CLASS 11

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

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

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

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.

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

arrange the folloing data in individual series..

4,4,5,3,6,4,5,3,4,5,6,3,9,6

in this question as no. 5 has appeared 3 time so in individual series we will write 5 3 times or just mention 3 in front of 5..? i m a lil bit confused..

Distinguish between Univariate and Bivariate frequency distribution.

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.

what is frequency array??

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

is frequency distribution series and continous series the same?????

17,22,17,32 and so on is given y

12is arriving as the mid point of preceeding classclassify 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.

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

The frequency distribution of two variables is known as

(a) Univariate Distribution

(b) Bivariate Distribution

(c) Multivariate Distribution

(d) None of the above

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

Thanks for answering my question. But what is the error in grouping ----has not been answered. so please be kind enough to answer it.

I have a doubt please answer the question

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

Thx

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

Convert the following data into less than and more than series X F 40-50 5 50-60 10 60-70 20 70-80 9 80-90 6

Give steps if construction Of continuous frequency distribution?

what do you meant by exclusive series inclusive series and open ended series5 points

differentiate between primary and secondary data?

why is Furniture industry ,a manufcturing industry?? BST

which method is more serious sampling error or nonsampling error and why ?

what is the importance of cumulative frequency distribution?

Define classification.

statistical methods are no substitute to common sense.Comment with example of your daily lifeWhat is a variable? Distinguish between a discrete and a continuous variable.
