Discuss the different methods of classification of data.

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.

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

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 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??

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.

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.

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

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

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.

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

5 points

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?

Define classification.

Give steps if construction Of continuous frequency distribution?

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

Prepare frequency distribution from the following weekly wages of 20 workers of a factory and also examine the error of grouping in each case.
