i want a project on consumer awareness in statistics.

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

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.

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

Discuss the different methods of classification of data.

What is ‘loss of information’ in classified data?

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

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

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

19,47,40,29,8,50,13,59,36,24

What is the difference between universe and sample?

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

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.

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

what is frequency array??

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

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.

The frequency distribution of two variables is known as

(a) Univariate Distribution

(b) Bivariate Distribution

(c) Multivariate Distribution

(d) None of the above

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

From the following data relating to weights of 30 students in kg 138,

164, 150, 131, 144, 125, 149, 157, 146, 148, 144, 168, 126, 138, 176, 163,

119, 150, 165, 146, 142, 135, 140, 135, 161, 145, 150, 156, 145, 128.

Obtain the range of weights of the students.

Write appropriate number of class intervals and obtain the

frequency distribution.

Find the number of students whose weight is

Less than 145kg

More than 155kg III Between 135 and 155 kg.

I have a doubt please answer the question

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

Thx

of students are 75, 84, 93, 102, 111, 120 and 129.

Find

A)Width of the class or size of the Class Interval.

B)The class limits [Inclusive series]

Class boundaries [Exclusive series]

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

in examination 25 students secured marks

Q3. Calculate the size of the class interval if mid-points in a frequency distribution are 25, 32, 39, 46, 53 and 60.

differentiate between primary and secondary data?

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

what is the importance of cumulative frequency distribution?

how to draw two way frequency table??quick answer???!!!!

Define classification.

Give steps if construction Of continuous frequency distribution?

plz correct the formula for midvalue given in study material.

It will help us to understand the main mathematical part of the chapter !

What is a variable? Distinguish between a discrete and a continuous variable.

Eg1: 0-10

10-20

20-30

Eg2: 0-10

11-20

21-30

Which one is correct and how to find out which one to use ?

What are the kinds of errors you would expect in a field survey by census method?

NSSO? Is it fulfilling it ??
