i want a project on consumer awareness in statistics.

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

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..!!

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

The area under rice in 50 districts is given below in acres. Show the distribution by frequency curve making a frequency table of 7 classes.

Discuss the different methods of classification of data.

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.

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?

30 families in an area spend the following monthly expenditure on food:

115 159 196 205 212 223

256 271 310 219 335 169

184 234 245 241 265 298

144 135 172 173 229 20

238 278 243 20 238 238

[i] prepare a frequency distribution with exclusive method.

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

respected authorities i think that the solution of 3rd example of continuous frequency distribution is wrong

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.

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."

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 do you meant by exclusive series inclusive series and open ended serieswhat is frequency array??

plz correct the formula for midvalue given in study material.

i want any topic on statistics frm which we can take out d statistical value, and can have so much information as i have tofill40 pages. its the same way we search on wikipedia but i cant find a suitable topic. so can you please help me with as many topics as you can give meWhat is the importance of statistics in modern economic set up? explain giving examples.

in 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.

From the following data relating to weights of 36 students in pounds, find out the following

- obtain the range of weights of students

-dinvide the range into appropriate no. of class intervals

-find the no. of students whose weight is less than 145 pounds, more than 155 pounds, between 135 and 155 pounds

138 164 150 144 168 126 142 135 140 131 144 125 138 176 163 135 161 145 149 157 146 119 150 165 150 156 154 140 146 128 173 115 135 176 167 187

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

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

Define organisation of data?

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

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

NSSO? Is it fulfilling it ??is frequency distribution series and continous series the same?????

5 points

differentiate between primary and secondary data?

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]

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

CLASS 11

what is the importance of cumulative frequency distribution?

is the formula for calculating mid point upper liimit +lower limit divided by 2 or

upper limit - lower limit divided by 2 becouse in study notes it is given upper limit - lower limit by2 and answer is not coming.

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.
