This document defines and discusses hypotheses. It begins by defining a hypothesis as an assumption or educated guess that is intended to be tested. It then provides definitions of hypotheses from several scholars and discusses their key characteristics. Hypotheses are categorized as null or alternative, directional or non-directional, and deductive or inductive. The document outlines guidelines for forming a hypothesis and testing it, including relating it to the research problem, making it clear and testable, and falsifiable. In summary, this document provides an overview of what a hypothesis is and best practices for developing and testing one.

Presentation deals with scientific process of Hypothesis formulation. Presentation would quench the thirst of beginners in social sciences researchers especially in commerce and Management towards basic understanding of Research Issues, Statement of Research Problem formulating hypothesis and research protocol. Presentation attempts to simplify process of narrowing the research problem from research issue and helps to formulate hypothesis scientifically. Deciding on appropriate title to research is equally important, this presentation discusses different context which helps to decide on appropriate title. Presentation includes case study examples for sound understanding.
A hypothesis is an assumption that is made based on some evidence. This is the initial point of any investigation that translates the research questions into predictions. It includes components like variables, population and the relation between the variables. A research hypothesis is a hypothesis that is used to test the relationship between two or more variables.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Meaning of Hypothesis
Definition of Hypothesis
Characteristics of Hypothesis
Categories of Hypothesis
Forming a Hypothesis
Testing of Hypothesis
3. Hypothesis means mere assumptions
or suppositions which are to be
proved or disproved.
Hypothesis is a formal question that is
intended to resolve.
4. A wild or wise guess
An educated guess
A tentative point of view
A proposition not yet tested
A preliminary explanation
A preliminary Postulate
5. “A hypothesis is a conjectural statement of the relation
between two or more variables”. (Kerlinger, 1956)
“Hypotheses are single tentative guesses, good hunches
– assumed for use in devising theory or planning
experiments intended to be given a direct experimental
test when possible”. (Eric Rogers, 1966)
“Hypothesis is a formal statement that presents the
expected relationship between an independent and
dependent variable.”(Creswell, 1994)
6. Guides/gives direction to the study/investigation
Defines Facts that are relevant and not relevant
Suggests which form of research design is likely to be the
most appropriate
Provides a framework for organizing the conclusions of the
findings
Limits the research to specific area
Offers explanations for the relationships between those
variables that can be empirically tested
Furnishes proof that the researcher has sufficient background
knowledge to enable her/him to make suggestions in order to
extend existing knowledge
Structures the next phase in the investigation and therefore
furnishes continuity to the examination of the problem
7. Related to problem
Clear & Precise
Amenable with time
Testable
States relation
Specific & Simple
8. A hypothesis
must make a prediction
must identify at least two variables
should have an elucidating power
should strive to furnish an acceptable explanation or
accounting of a fact
must be falsifiable meaning hypotheses must be
capable of being refuted based on the results of the
study
must be formulated in simple, understandable terms
should correspond with existing knowledge
In general, a hypothesis needs to be unambiguous,
specific, quantifiable, testable and generalize-able.
9. Can be categorized in different ways
1. Based on their formulation
Null Hypotheses and Alternate Hypotheses
2. Based on direction
Directional and Non-directional Hypothesis
3. Based on their derivation
Inductive and Deductive Hypotheses
10. Null hypothesis always predicts that there is
no relationship between the variables being
studied.
The researcher wishes to disapprove this
hypothesis.
It is denoted by H0
For example:
◦ “There is no relationship between learning and
intelligence.”
11. The alternate hypothesis always predicts
that there will be a relationship between the
variables being studied.
It is denoted by Ha
Non Directional
Hypothesis
Directional
Hypothesis
12. If the hypothesis simply predicts that there will be a
difference between the two groups, then it is a non-
directional hypothesis. It is non-directional because it
predicts that there will be a difference but does not
specify how the groups will differ.
e.g. Lack of attention leads to failure.
If, however, the hypothesis uses so-called comparison
terms, such as “greater,”“less,”“better,” or “worse,” then
its a directional hypothesis. It is directional because it
predicts that there will be a difference between the two
groups and it specifies how the two groups will differ.
e.g. A person whose attitude is positive towards studies
is more likely to succeed than one who do not.
13. A hypothesis is formulated after
the problem has been stated and
the literature study has been conducted
It is formulated when the researcher is totally
aware of the theoretical and empirical
background to the problem
Hypotheses is formulated using induction and
deduction method
Hypothesis will be generated from the
problem statement.
14. Read the problem statement thoroughly.
Narrow or limit it and express it as a research
question.
A research hypothesis has two elements(variables)
that are in relation to one another.
Avoid judgmental words in hypothesis.
Hypothesis must involve an issue or question that
cannot be answered exclusively.
It is best to choose a hypothesis where there is some
level of familiarity with the disciplines that are most
relevant to the topic.
All the terms must be clearly understood and defined.
It is to be noted that hypothesis may change over
time as the research progresses.
