  2. They serve as the basis for determining assumptions.
  3. They serve as basis in determining the relevance of the data.
  4. They serve as the basis for the explanation or discussion about the data gathered.
  5. They help the researcher in consolidating his findings and in formulating his conclusions.
45
Q

Guidelines in the Formulation of Hypothesis

A
  1. In experimental investigations, hypothesis have to be explicit , they have to be expressed as well as in comparative and correlational studies.
  2. In descriptive and historical investigation, hypothesis are seldom express if not entirely absent.
  3. Hypothesis are usually stated in the null form because testing a null hypothesis is easier than a hypothesis in the operational form.
  4. Hypothesis is formulated from the specific question upon which they are based.

Controls are difficult to apply especially if it is done with human beings

63
Q

Validity of Experimental Designs

A

-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.

64
Q

Threats to Internal Validity

A

 Selection bias
 History
 Maturation
 Testing
 Instrumentation change
 Mortality

65
Q

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.

A

Selection bias

66
Q

occurs when some event other than the experimental treatment occurs during the course of a study, and this event influences the dependent variables.

A

History

67
Q

becomes a threat when changes that occur within the subjects during an experimental study influence the study results.

A

Maturation

68
Q

the testing threat may occur in studies where a pretest is given or where subjects have knowledge of baseline data.

A

Testing

69
Q

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

A

Instrumentation change

70
Q

occurs when the subject dropout rate is different between the experimental and comparison groups.

A

 Mortality

71
Q

Threats to External Validity

A

 Hawthorne Effect
 Experimenter Effect
 Rosenthal Effect
 Reactive Effects of the Pretest (measurement effect)

72
Q

________ occurs when the participants respond in a certain manner because they are aware that they are being observed.

A

Hawthorne Effect

73
Q

is a threat to study results that occurs when researcher characteristics or behaviors influence subject behaviors. (Usually discussed only in experimental research)

A

Experimenter Effect

74
Q

_______ – 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)

A

Rosenthal Effect

75
Q

occurs when subjects have been sensitized to the treatment through taking the pretest.

A

Reactive Effects of the Pretest (measurement effect)

76
Q

Types of Experimental Designs

A
  1. True Experimental Designs
  2. Quasi-experimental Designs
77
Q

these types of design gives the researchers some confidence that the independent variable was the cause of the change in the dependent variable.

A

True Experimental Designs

78
Q

Three criteria for a True Experimental designs:

A
  1. The researcher manipulates the experimental variable(s).
  2. At least one experimental and one comparison group are included in the study.
  3. Subjects are randomly assigned to either the experimental or the comparison group.
79
Q
  • 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.
A

Pretest-Posttest Control Group Design

80
Q

– are those in which there is either no comparison group or subjects are not randomly assigned to groups.

A

Quasi-experimental Designs

81
Q

is similar to the pretest-posttest control group design except that there is no random assignment of subjects to the experimental and comparison groups

82
Q

the researcher periodically observes or measures the subjects.

A

o Time series Design

83
Q

True or False
