Questionnaire /Schedule design is a systematic approach/process of including relevant questions in a questionnaire in such a way that the best or accurate responses are obtained from respondent with very little / no discomfort on the part of the respondent as well as the enumerator.The most important part of the survey process is the creation of questions that accurately measure the opinions, experiences and behaviors of the target group. Questionnaire / Schedules design is one of the most critical stages in the survey research process and therefore has to be given the utmost attention. This power point presentation will guide you through schedules and questionnaire design.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. Overview:
Census and Sampling are
methods of collecting data
about the Populace.
A Sample is a portion and a Census measures everyone
in the whole country
3. What is Census ?
A census is the procedure of systematically acquiring
and recording information about the members of a given
population.
Under this method, data is collected for each and
every unit viz. person, household, field, shop, factory
etc…, as the case may be of the population or universe.
For example, if the average wage of
workers working in a sugar factory is to
be calculated, then wage figures would
be obtained by dividing the total wages
which all the workers received by no of
workers working in the sugar industry.
4. What is Sampling ?
Sampling is simply the process of learning about
the population on the basis of a sample drawn from it.
In the Sampling technique, instead of every unit
of universe only a part of the universe is studied and the
conclusion is drawn on that basis for the entire universe.
The theory of sampling has taken place only in
recent years, the idea of sampling is pretty old.
Since times immemorial have examined a
handful of grains to ascertain the quality of entire
lot.
A housewife examines only a two or three
grains of boiling rice to know whether the pot of
rice is ready or not.
a bussinessman places orders for material
by examining only a small sample of the same.
5. Difference :
In Census, each and every unit of the population is
studied.
but only few units of the population studied is
studied in Sampling.
Census refers to periodic collection of information
about the populace from the entire population.
However, if the next Census is far away, Sampling is
the most convenient method of obtaining data about the
population.
6.
Census method demands a large amount of
finance, time and labor.
Relatively less amount of finance, till labor is
required for Sampling.
Results obtained by Census are quite reliable.
Results obtained by Sampling are less reliable.
It is more suitable to use Census Method if population
is heterogeneous in nature.
and It is more suitable to use Sampling Method if
population is homogeneous in nature.
7.
Samples have a margin of error though, which gets
lower as the sample size increases. In other words, sampling
more people means obtaining better data.
Instead, this type of error is not present in Census as
each and every part of the geographical area has to be
approached for data collection.
However,
Difference between the Sample result and census result under
the same circumstances is known as ‘Sample Error’.
and this error can be minimized by taking large samples.
8. Conclusion :
Data collected through census is more accurate
because it takes the entire population into account
while the data collected through sampling is close to
real information but has scope for error because the
information is collected from a sample population.
This does not mean that data collected through
sampling is not important. Both the methods have their own
importance and the data collected through tem plays
significant role in formulation of policies especially for the
weaker sections.
