Types of Hypothesis - Research Hypothesis Flashcards
a tentative statement saying what you expect to find in your research
HYPOTHESIS
a prediction based on existing knowledge
HYPOTHESIS
Steps on formulating Hypothesis
Step 1: Ask a question
Step 2: Do some preliminary research
Step 3: Formulate your Hypothesis
Step 4: Refine your Hypothesis
Step 5: Phrase your hypothesis in 3 ways
Step 6: Write a Null Hypothesis
begins with a research question that you want to answer
Step1: Ask a question
The question should be?
Focused
Specific
Researchable
Your initial answer to the question should be based on what is already known about the topic
Step 2: Do some preliminary research
look for theories and previous studies
Step 2: Do some preliminary research
write down your initial answer to the question in a clear and concise sentence
Step 3: Formulate your Hypothesis
in this step, you have to make sure the hypothesis is SPECIFIC and TESTABLE
Step 4: Refine your Hypothesis
3 Forms in Step 5
- If… Then…
- Correlation/ Effect
- Comparison
assumes there’s no effect between the variables
Step 6: Write a Null Hypothesis
a statement that can be tested by scientific research
HYPOTHESIS
test relationship between two or more things
HYPOTHESIS
start it before doing the data collection
HYPOTHESIS
states prediction of what your research will find
HYPOTHESIS
it is the tentative answer of your research question
HYPOTHESIS
not just a guess, it should be based on the existing theory
HYPOTHESIS
it is tetable (supported with scientific method)
HYPOTHESIS
propose a relationship between two or more variable
HYPOTHESIS
something the researchers observes and measure
DEPENDENT VARIABLE
something the researchers changes or control
INDEPENDENT VARIABLE
How to develop Hypothesis
- Ask a Question
- Do Some Preliminary Research
- Formulate your Hypothesis
- Refine your Hypothesis
- Phrase your Hypothesis in 3 Ways
- Write a Null Hypothesis
this step of hypothesis should be focused and specific
Step 1: Ask a Question
Considered as an intelligent guess or prediction, that gives
directional to the researcher to answer the research question.
HYPOTHESIS
are defined as the formal statement
of the tentative or expected prediction or explanation of the
relationship between two or more variables in a specified
population.
HYPOTHESIS
Contributions of Hypothesis
It provides clarity to the research problem and
research objectives.
It describes, explains, or predicts the expected results
or outcome of the research.
It may lead to the formulation of another hypothesis.
Types of Hypothesis
Simple
Complex
Empirical
Null
Alternative
is one in which there exists a relationship
between two variables; one is called the independent variable or
cause or the other is the dependent variable or effect.
SIMPLE HYPOTHESIS
is one in which a relationship among
variables also exists.
COMPLEX HYPOTHESIS
In this type, dependent and independent variables are more than
two.
COMPLEX HYPOTHESIS
means it is based on evidence.
EMPIRICAL
refers to the use of a
working hypothesis that can be tested using observation and
experiment.
EMPIRICAL
is produced by experiment and observation.
EMPIRICAL DATA
It is the simplest form of hypothesis.
EMPIRICAL HYPOTHESIS
In simple cases, investigation and research are adequately
implemented by resuming a question.
EMPIRICAL HYPOTHESIS
denotes that there is no
significant difference between specified
populations, any observed difference being
due to sampling or experimental error.
NULL HYPOTHESIS
It is denoted by Ho.
NULL HYPOTHESIS
denoted by H1 or Ha
ALTERNATIVE HYPOTHESIS
Claims that there is an effect
ALTERNATIVE HYPOTHESIS
a hypothesis that sample observations are influence by some non-random cause
ALTERNATIVE HYPOTHESIS
Characteristics of Hypothesis
A Hypothesis:
- must be capable of verification
- must be related to the existing body of knowledge
- needs to be precise, simple and specific
