What are you looking for?

Syllabus

i want a project on consumer awareness in statistics.

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.

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

Discuss the different methods of classification of data.

What is ‘loss of information’ in classified 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

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

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

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

what is frequency array??

What is the difference between universe and sample?

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.

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

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

Distinguish between Univariate and Bivariate frequency distribution.

The frequency distribution of two variables is known as

(a) Univariate Distribution

(b) Bivariate Distribution

(c) Multivariate Distribution

(d) None of the above

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.

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

The class midpoint is equal to:

(a) The average of the upper class limit and the lower class limit.

(b) The product of upper class limit and the lower class limit.

(c) The ratio of the upper class limit and the lower class limit.

(d) None of the above.

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

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

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?

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

[i] prepare a frequency distribution with exclusive method.

differentiate between primary and secondary data?

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

what is homogenius and heterogenious data

what is the importance of cumulative frequency distribution?

Define classification.

Give steps if construction Of continuous frequency distribution?

statistical methods are no substitute to common sense.Comment with example of your daily lifePrepare frequency distribution from the following weekly wages of 20 workers of a factory and also examine the error of grouping in each case.
