This document defines and explains key concepts related to research hypotheses. It begins by defining a hypothesis as a testable statement that attempts to explain facts or phenomena. The document then outlines characteristics, functions, types (including scientific, working, null, and alternative hypotheses), parameters for a good hypothesis, and how hypotheses compare to laws and theories. It concludes by emphasizing that hypotheses are derived from theories and express conjectured relationships between variables in testable statements.
This PPT slide presentation deals with the Meaning of hypothesis, Types of hypothesis, Parameters of a good hypothesis, Importance of hypothesis, Source of hypothesis, Format of hypotheis & Formulation of testable hypothesis.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. INTRODUCTION
Research hypotheses are the
specific testable predictions made about the
independent and dependent variables in the
study. Hypotheses are couched in terms of the
particular independent and dependent
variables that are going to be used in the
study.
4. MEANING
A hypothesis is an educated
guess or proposition that attempts to explain
a set of facts or natural phenomenon. It is
used mostly in the field of science, where
the scientific method is used to test it.
It can be defined as a
tentative, yet testable statement, which
provides what you want to find in your
empirical data.
6. FUNCTIONS
The important functions of hypotheses
are as follows:
• Bringing clarity to the research problem
• provides a study with focus
• signifies what specific aspects of a research
problem is to investigate
7. Functions…..
what data to be collected and what not to be
collected
enhancement of objectivity of the study
formulate the theory
enable to conclude with what is true or what
is false
8. BASICS OF HYPOTHESES
The two basic types of hypotheses are
scientific and working.
A scientific hypothesis is based on experiments
and observations from the past that cannot
be explained with current theories.
A working hypothesis is one that is widely
accepted and becomes the basis of further
experimentation.
9. TESTING V/S TESTED HYPOTHESES
A hypothesis can be testing a
concept or it can be developed as a result of
study:
A testing hypothesis is one that can be
tested, meaning you can measure both what
is being done (variables) and the outcome.
A tested hypothesis is tested with
research, such as in a research study in social
science.
10. GOAL OF HYPOTHESES
Regardless of the type of
hypothesis, the goal of a hypothesis is to help
explain the focus and direction of the
experiment or research. As such, a hypothesis
will:
State the purpose of the research
Identify what variables are used
11. PARAMETERS OF A GOOD HYPOTHESES
In order to be a good hypothesis that
can be tested or studied, a hypothesis:
Needs to be logical
Must use precise language
Should be testable with research or
experimentation
A hypothesis is usually written in a form where it
proposes that if something is done, then something
else will occur.
13. Working hypothesis
The working or trail hypothesis is
provisionally adopted to explain the relationship
between some observed facts for guiding a
researcher in the investigation of a problem.
A Statement constitutes a trail or working
hypothesis (which) is to be tested and
conformed, modifies or even abandoned as the
investigation proceeds.
14. Null hypothesis
A null hypothesis is formulated against the
working hypothesis; opposes the statement of
the working hypothesis
....it is contrary to the positive statement
made in the working hypothesis; formulated
to disprove the contrary of a working
hypothesis
When a researcher rejects a null
hypothesis, he/she actually proves a working
15. In statistics, to mean a null hypothesis
usually Ho is used. For example,
Ho Q = O
where Q is the property of the
population under investigation
O is hypothetical
16. Alternate hypothesis
An alternate hypothesis is formulated when a
researcher totally rejects null hypothesis
He/she develops such a hypothesis with
adequate reasons
The notion used to mean alternate hypothesis
is H1 Q>O
i.e., Q is greater than O
17. EXAMPLES
Working hypothesis: Population
influences the number of bank branches in a town
Null hypothesis (Ho): Population do not
have any influence on the number of bank
branches in a town.
Alternate hypothesis (H1): Population has
significant effect on the number of bank branches
in a town. A researcher formulates this hypothesis
only after rejecting the null hypothesis.
18. COMPARING HYPOTHESIS, LAW AND
THEORY
There are three types of scientific
statements:
Hypothesis
Law
Theory
A hypothesis will give a plausible explanation
that will be tested. It can also explain future
phenomenon that will need to be tested.
19. Once a hypothesis has been widely
accepted, it is called a law. This means that it
is assumed to be true and will predict the
outcome of certain conditions or experiments
A scientific theory is broader in scope and
explains more events that a law. After
hypotheses and laws have been tested many
times, with accurate results, they become
theories.
20. CONCLUSION
Usually the literature review
has given background material that justifies
the particular hypotheses that are to be
tested. Hypotheses are derived from the
theory on which your conceptual model is
based and are often relational in nature.
Hypotheses are conjectured relationships
between two or more variables expressed in
the form of testable statements.
