Research Hypothesis Testing
_________ states your expectations concerning the relationship between the variables in your research problem.
Hypothesis Test
_______ a testable statement of a potential relationship between two or more variables.
Hypothesis Test
- statistically, it becomes the evidence on why and how the decision was made over the problem tested.
Hypothesis Test
Purpose, Functions, and Importance of Hypotheses
- They help the researcher in designing his study : what methods , research instruments , sampling design , and statistical treatments to use , what data to gather , analyze , interpret on the study.
- They serve as the basis for determining assumptions.
- They serve as basis in determining the relevance of the data.
- They serve as the basis for the explanation or discussion about the data gathered.
- They help the researcher in consolidating his findings and in formulating his conclusions.
Guidelines in the Formulation of Hypothesis
- In experimental investigations, hypothesis have to be explicit , they have to be expressed as well as in comparative and correlational studies.
- In descriptive and historical investigation, hypothesis are seldom express if not entirely absent.
- Hypothesis are usually stated in the null form because testing a null hypothesis is easier than a hypothesis in the operational form.
- Hypothesis is formulated from the specific question upon which they are based.
Types/Classifications of Hypothesis
- Simple hypothesis
- Complex hypothesis
_______ states the relationship between one independent and one dependent variable
Simple hypothesis
________ states the relationship where two or more independent variables, two or more dependent variables, or both, are being examined in the same study
Complex hypothesis
True or False
Hypothesis is not required if only one variable is being examined.
True
assumes that no relationship exists between two variables, and it is the null hypothesis that is subjected to statistical analysis.
Null Hypothesis (Hο)
states the expected relationship between variables
Research hypothesis or Alternative hypothesis (H₁)
True or False
Hypothesis should be stated before gathering of data, this will be the basis in rejecting or accepting the hypothesis.
False
Level of significance should be stated before gathering of data, this will be the basis in rejecting or accepting the hypothesis.
it merely predicts that a relationship exists.
Non-directional research hypothesis
it further predicts the type of relationship
Directional hypothesis
Hypothesis Criteria
- should be written in a declarative sentence
- should be written in present tense
- it should contains the population
- it should contains the variables
- should reflect the problem statement
- should be empirically testable
are conducted when little is known about the phenomenon of interest. Usually it is in Qualitative research.
Exploratory studies
Research designs
Exploratory studies
Descriptive studies
Explanatory studies
phenomena are described or the relationship between variables is examined.
Descriptive studies
search for causal explanations and are much more rigorous than exploratory or descriptive studies. It is usually experimental
Explanatory studies
_____ it is involve with the cause and effect relationships.
Experimental Research
It is involve in the manipulation or control of the independent variables (cause) and measurement of dependent variables (effect)
Experimental Research
True or False
Controls is easy to apply especially if it is done with human beings
False
Controls are difficult to apply especially if it is done with human beings
Validity of Experimental Designs
-CONTROL OF EXTRANEOUS VARIABLES that may influence study results
-CONTROL OF THREATS TO INTERNAL VALIDITY that may influence the dependent variables other than the independent variables.
-CONTROL OF THREATS TO EXTERNAL VALIDITY that may affect the degree to which study results can be generalized to other people and other settings.
Threats to Internal Validity
Selection bias
History
Maturation
Testing
Instrumentation change
Mortality
it occurs when study results are attributed to the experimental treatment or the researcher’s manipulation of the independent variable when, in fact, the results are due to subject differences before the independent variable was manipulated.
Selection bias
occurs when some event other than the experimental treatment occurs during the course of a study, and this event influences the dependent variables.
History
becomes a threat when changes that occur within the subjects during an experimental study influence the study results.
Maturation
the testing threat may occur in studies where a pretest is given or where subjects have knowledge of baseline data.
Testing
involves the difference between the pretest and posttest measurement caused by a change in the accuracy of the instrument rather than as a result of the experimental treatment
Instrumentation change
occurs when the subject dropout rate is different between the experimental and comparison groups.
Mortality
Threats to External Validity
Hawthorne Effect
Experimenter Effect
Rosenthal Effect
Reactive Effects of the Pretest (measurement effect)
________ occurs when the participants respond in a certain manner because they are aware that they are being observed.
Hawthorne Effect
is a threat to study results that occurs when researcher characteristics or behaviors influence subject behaviors. (Usually discussed only in experimental research)
Experimenter Effect
_______ – is used to indicate the influence of an interviewer on respondents’ answers
- it has been shown that researcher characteristics such as gender, dress, and type of jewelry may influence respondents’ answers to questions. (Usually discussed in non experimental research)
Rosenthal Effect
occurs when subjects have been sensitized to the treatment through taking the pretest.
Reactive Effects of the Pretest (measurement effect)
Types of Experimental Designs
- True Experimental Designs
- Quasi-experimental Designs
these types of design gives the researchers some confidence that the independent variable was the cause of the change in the dependent variable.
True Experimental Designs
Three criteria for a True Experimental designs:
- The researcher manipulates the experimental variable(s).
- At least one experimental and one comparison group are included in the study.
- Subjects are randomly assigned to either the experimental or the comparison group.
- the subjects are randomly assigned to groups
- a pretest is given to both groups
- the experimental group receives the experimental treatment and the comparison group receives the routine treatment or no treatment
- a posttest is given to both groups.
Pretest-Posttest Control Group Design
– are those in which there is either no comparison group or subjects are not randomly assigned to groups.
Quasi-experimental Designs
is similar to the pretest-posttest control group design except that there is no random assignment of subjects to the experimental and comparison groups
Nonequivalent Control Group Design
the researcher periodically observes or measures the subjects.
o Time series Design
True or False
In time series design, the experimental treatment is administered between two of the observations.
True
is descriptive in nature because there is no manipulation or control of variables and the researcher can only describe the phenomenon as it exists.
Non-experimental Research
Types of Non-Experimental Research
Survey studies
Correlational Studies
are investigations in which self-report data are collected from samples with the purpose of describing populations on some variable or variables of interest.
Ex. Psychiatric nurses’ self-awareness
Survey studies
the researchers examines the strength of relationships between variables by determining how changes in one variable are associated with changes in another variable.
Correlational studies
indicates the magnitude and direction of the relationship between two variables.
Correlation coefficient
means that as the value of one variable increases, the value of the other variable increases
Positive relationship
inverse relationship, means that as the value of one variable increases, the value of the other variable decreases.
Negative relationship
examines the differences between intact groups on some dependent variable of interest.
Comparative Studies
Classifications of Comparative Studies
o Retrospective Studies (ex post facto)
o Prospective Studies
the dependent variable (effect) is identified in the present (a disease condition, for example), and an attempt is made to determine the independent variable (cause of the disease) that occurred in the past.
Retrospective Studies (ex post facto)
the independent variable or presumed cause (for example, family history of schizophrenia) is identified at the present time, and then subjects are followed in the future to observe the dependent variable (incidence of schizophrenia in the family)
Prospective Studies
are concerned with the development, testing, and evaluation of research instruments and methods.
Methodological Studies
focuses on gaining insight and understanding about an individual’s perception of events
Qualitative research
Who defined qualitative research attempts to obtain rich, real, deep and valid data, aims for hard, replicable and reliable data?
(Porter, 1989)
is concerned with in-depth descriptions of people or events, and data are collected through unstructured interviews and participant observation.
Qualitative research
Types of Qualitative Research
Phenomenological Studies
Ethnographic Studies
Grounded Theory Studies
Historical Studies
examine human experiences through the descriptions that are provided by the people involved. (Lived experiences)
Phenomenological Studies
involve the collection and analysis of data about cultural groups
Ethnographic Studies
Who wrote that ethnography means “learning from people?
Cameron (1990)
Who described ethnographic studies as the systematic process of observing, detailing, describing, documenting, and analyzing the life ways or particular patterns of a culture (or subculture) in order to grasp the life ways or patterns of the people in their familiar environment?
Leininger (1985)
are studies in which data are collected and analyzed and then a theory is developed that is grounded in the data
Grounded Theory Studies
it concern the identification, location, evaluation, and synthesis of data from the past.
Historical Studies
Two types of Evaluation of Historical Research
External criticism
Internal criticism
is concerned with the authenticity or genuineness of the data.
External criticism
examines the accuracy of data.
Internal criticism
are in-depth examinations of people or groups of people
Case Studies
