Correlation is said to exists between two variables if they vary directly or indirectly together.

• Demand and supply, Height and weight -positive correlation 
• Price and demand, price and sales-negative correlation 
• Height or Weight of a student and marks obtained in an exam-zero correlation.

1. Positive correlation 

2. Negative correlation 

3. zero correlation

Frequency is the number of times an item occur (or repeat itself) in the series.

A few representative units selected at random from the population.

The two stages of statistical enquiry are: 

1. Planning and preparation. 

2. Execution of the survey.

Arranging of data in different classes according to a given order is called series.

Relative Error is the ratio of absolute error and the estimated value.

Sampling survey implies enumeration of few representative units selected at random from the population. 

Ex: – Survey of market of prices of food grains at selected places

In planning the following points are to be carefully considered. 

1. Object of an enquiry 

2. Scope of the enquiry 

3. Units used for collection and measurement 

4. Sources of data 

5. Method of collection of data 

6. Framing a format 

7. Accuracy level 

8. Type of enquiry

Secondary data is the data which has been already collected by someone and analyzed by enumerators. They are not original in nature. Secondary data is also called second hand data. And which are published in Journals, Mazgines, Newspapers, maintained as office records.

Statistical error is the difference between the estimated value and the actual value.

A Statistical enquiry means a search for knowledge through statistical methods.

The Causes of Errors are: 

Errors of origin : The error that occurs due to improper definition of statistical units, defective questionnaire and wrong method of enquiry is called the Error of origin. 

Error of inadequacy: The error that occurs due to incomplete data or insufficient data is called Error of inadequacy. 

Error of manipulation : The error that occurs at the time of analysis (clerical errors) is called Error of manipulation.

The various steps to be considered at the execution are as follows: 

1. Setting a team of administrators 

2. Designing of questionnaire 

3. Selection and training of enumerators 

4. Field work by enumerators and supervision 

5. Follow up work in the case of non response 

6. Analysis of collected data 

7. Preparation of final report

The sources of secondary are published and unpublished source. 

Published source:- 

1. Official publication of the state and central government 

2. Foreign or Internation bodies like UNO, IMF etc. 

3. Journals, periodicals, Newspapers, Magazines etc. 

Unpublished source:- 

1. Unpublished records maintained by government offices, Municipal offices, panchayat offices etc. 

2. Unpublished records maintained by research scholars, research centers, etc.

Biased errors : The errors that occur with the notice of the investigator are called biased errors . These errors are prejudiced errors. 

Unbiased errors : The errors that occur without the notice of the investigator are called unbiased errors. These errors occur due to chance causes (which cannot be controlled)

Absolute Error is the arithmetic difference of actual value and the estimated value. 

Absolute Error = Actual value – Estimated val ue 

A.E = a – e.

The different sources of secondary data are: 

1. Published sources 

2. Unpublished sources.

There are two types of measurements of errors: 

1. Absolute error 

2. Relative error

Data which are collected by the investigator for the first time, freshly obtained directly from the field is called primary data. They are original in nature.

The different methods of collection of primary data are: 

1. Direct personal observation. 

2. Indirect oral interview. 

3. Information through agencies. 

4. Mailed questionnaires. 

5. Schedules sent through enumerator.

1. Direct personal observation: In this method the investigator collects the required information by personal observation of the units, through the enumerator, from the informants. This methods is successively employed-Where the field of enquiry is confidential, small, greater accuracy and sufficient time is available.

Merits: This method is most reliable, accurate and confidential.

Demerits: This method is expensive, time consuming and this method becomes difficult where the enquiry field is large. In this method there is chance of personal bias in collection of data, needs trained and skilled personnel.

2. Indirect oral interview: This method is applied, where the required information from the informant is not possible to obtain by direct interview method. In this method the investigator/enumerator approaches the witnesses or third parties, who are capable to supply the necessary information about the first person/informant.

Merits: This method is simple, convenient, free from bias and successively employed by New paper, Broadcasting, Investigating agencies. 

Demerits: In this method there is an ample scope of influencing the enquiry by the third person.

3. Information through agencies 

Under this method, local agents or correspondents will be appointed. They collect the information and transmit it to the investigator. They may apply any method according to the intensity of the situation. Agents who collect information from the informants are generally called correspondents.

This method is generally adopted in those cases where the information is to be obtained at regular intervals from a wide area. News papers are the-examples of collection of information through agencies.

Merits : 

• This method is very cheap and economical. 
• It is useful where information is needed regularly. 

Demerits:

• The information may be biased. 
• It is difficult to maintain the degree of accuracy and uniformity.

4. Mailed questionnaire 

Questionnaire is a list of questions where the answers are filled by the informants and these answers are the required information for the investigation. The questionnaire is sent to the respondents, who are expected to write the answers in the space provided in the questionnaire.

The questionnaire will by sent to the informants through mail. A covering letter is also sent along with the questionnaire, requesting the informants to extend their full cooperation by giving the correct information and return the duly filled questionnaire with in a fixed time. This method is appropriate in cases where informants are spread over a wide area and are literates.

Merits: 

• This method is most economical. 
• It saves manpower. 
• It can be widely used, where the area of investigation is large. 

Demerits: 

• This method cannot be used if the informants are illiterates. 
• In this method many informants will not respond. 
• In the case of non response, follow up work is essential.

5. Schedules sent through enumerators: It is a widely used method of collection of primary data. A number of enumerators are selected and trained for this purpose.

Here, the trained investigator collects data through enumerators. The enumerators contact the informants and collect the information which is called schedule method. Schedule is a list of questions where the facts will be supplied by informants and recorded by enumerator.

Merits 

• This method is very useful where the informants are illiterates. 
• In this method the rate of non response is less. 

Demerits 

• In this method the training of enumerators is essential. 
• This method is time consuming. 
• Personal bias of the enumerators may lead to failure of enquiry.

To get a better continuity between the class interval of a frequency distribution exclusive class intervals are used, so, if the frequency distribution is in inclusive class intervals isconverted into exclusive class intervals using correction factor.

If in a bivariate frequency distribution, if the distribution of only one variable is considered, the distribution is called marginal frequency distribution. 

If in a bivariate frequency distribution, if the distribution of only one variable is formed subject to the condition of the other variable it is called conditional frequency distribution.

A systematic presentation of the values taken by a variable and the corresponding frequencies is called Frequency distribution.

i. Width of the class: The difference between the upper and lower limits of class called width of the class. It is denoted by c or i. i/c = Upper limit(UL) – Lower limit(LL)

ii. Class mid point: The central value of a class called mid value/point; m/x = LL+UL/2

iii. Define Frequency Density: The frequency per unit of class interval is the frequency density. i.e. frequency density = (Frequency the class/width of the class) = f/w

iv. Relative frequency: Relative frequency.. is the ratio of frequency of class to the total frequency of the distribution Relative Frequency f/N.

If in a class, both lower and upper limits are included in the same class are inclusive class intervals, eg. 0-9, 10-19, 20-29… If in a class, the lower limit is included in the same class but the upper limit is included in the next class are exclusive class intervals, eg. 0-10, 10-20, 20-30…

i Frequency, class frequency: Frequency refers to the number of times an observation repeated (f). The number of observations corresponding to a particular class is known as the class Frequency Class frequency is a positive integer including zero

ii. Class limits:Class limits- Lowest and the highest values that are taken to define the boundaries of the class are called class limits

iii. Range of the class: It is the difference between highest and lowest value in the data, i.e., Range = H.V. – L.V

The correct option is: (A) 33/2

Explanation:

We have, 36x + 24y = 702

and 24x + 36y= 558

Simplifying above equations, we get

6x + 4y = 117 ....(1)

and 4x + 6y = 93    .....(2)

Multiplying eq. (1) by 3, eq. (2) by -2 and then adding, we get 

18x + 12y - 8x - 12y = 351 - 186

=> 10x = 165 => x = 165/10 = 33/2

The essence of Buddhism lies in the four noble truths, i.e., sufferings, cause of sufferings, eradication of sufferings and path to eradicate sufferings. Buddha believed that this world is full of misery and sorrow. The cause of misery and sorrows is desire. He said that the result of our Karmas (actions) whether good or bad affect us both in this life and the next.

Bhamha Shah is known as a great donor and benefactor because he had surrendered his all assets to Maharana Pratap in times of crises.

वित्त की समस्या।

कक्षाध्यापक ने छात्र को बतलाया कि कविता में चार पंक्तियाँ होती हैं और प्रत्येक पंक्ति में .31 अक्षर होते हैं। कविता के लिए जो भी समस्या दी जाए उस वाक्य (समस्या) के अन्तिम अक्षर के चार तुकें जैसे-आई है रहे तो भाई है, छाई है, खाई है इस प्रकार के जमा लेना और उसे प्रत्येक वाक्य के अन्त में लगा देना, कविता तैयार हो जाएगी।

बड़े उद्योग वह उद्योग होते हैं जिनमें निवेश की मात्रा बहुत ज्यादा होती है।

बालक गोपाल प्रसाद अपने अध्यापक की मदद से कविता की रचना करना सीख गए।जिससे वे कवि सम्मेलन में पहली बार अपनी लिखी कविताएँ सुना सके और अपनी पहली ही कविता से कवि बन गए।

गोपाल प्रसाद जी स्क्यं कविता नहीं बनाया करते थे, बल्कि अपने एक पड़ोसी रामलाल जी से अपने नाम की कविता लिखवाकर स्कूलों में सुनाते थे। चूँकि नुमाइश में होने वाले कवि सम्मेलन में वाक्य दिए जाते हैं, जिस पर कविता बनानी होती है। यही सोचकर गोपालप्रसाद जी को धक्का लगा।

सभी श्रोता प्रशंसा और आश्चर्य से बालक गोपालप्रसाद को देखने लगे। हेडमास्टर मुकुल बिहारी लाल जी ने बालक को दौड़ कर गोदी में उठा लिया और जनता ने उनके कवि होने की घोषणा कर दी।

विद्यालय में होने वाले संगीत समारोह में लेखक को न बुलाकर इनके साथी लडकों को कविता सुनाने के लिए बुलाया जाता था। संगीत सुनाने पर तालियों की तड़तड़ाहट बहुत क्षीण होती जबकि कविता सुनाने के बाद तालियों की खूब तड़तड़ाहट होती थी। इसी कारण लेखक के मन में भी कविता सुनाने की इच्छा होने लगी।

1. खादी तथा ग्रामोद्योग कमीशन की स्थापना की गई है जो इन उद्योगों की विशिष्ट आवश्यकताओं की देखभाल करता है।
2. इनकी बिक्री को प्रोत्साहन देने के लिए आर्थिक सहायता दी जाती है।

बालक गोपालप्रसाद को संगीत का ज्ञान अपने परिवार से विरासत में मिला था। इसलिए उसे संगीत के घंटे का मॉनिटर बनाया जाता था।
