Q

Ex post facto research literally means

A

“After-the-fact”

26
Q

Investigators have no control over the variables in the sense of being able to manipulate them.

A

Ex-Post Facto Research

27
Q

Report only what has happened or what is happening.

A

Ex-Post Facto Research

28
Q

Looks first to the effects and tries afterward to determine causes.

A

Ex-Post Facto Research

29
Q

Is there a difference in the literacy level of students between their cultural and educational family background?

A

Ex-Post Facto Research

30
Q

Is there a significant difference in the post-test scores of the control group and experimental group?

A

Experimental Research

31
Q

How does the amount of uninterrupted darkness influence the anthesis of selected Zea mays L. saccharata cultivars?

A

Experimental Research

32
Q

Orientation in Research

A

Retrospective and Prospective

32
Q
  • Starts with an effect and seeks possible causes
  • Phenomenon existing in the present is linked to phenomena that occurred in the past
  • Begins with the dependent variable and then examines whether it is correlated with one or more antecedent independent variables
A

Retrospective

32
Q

Correlation is a synonym for _____

A

association

33
Q

Studies relationships between two or more variables in a single group of participants without any attempt to influence them

A

Correlational Research

33
Q

Establishes the existence of relationship between or among variables of the study

A

Correlational Research

33
Q

Starts with a cause and investigates its effects on some variable

A

Prospective

34
Q

Does not consider cause-and-effect relationships

A

Correlational Research

35
Q

Lack of random assignment limits the generalizability of the results

A

Correlational Research

36
Q

Classification of variables

A

Quantitative Variable and Qualitative Variable

36
Q

Two requirements for variables:

A
  1. Values for any variable must be any mutually exclusive from one another
    a. Each subject can have only a single value on each variable in the study
  2. Values for any variable must be exhaustive.
    a. All research participants can be assigned, or self-selected, into a value provided.
36
Q

_____ is most appropriate research when a phenomenon occurrs naturally; or it is not practical to manipulate the independent variables; or the control of
independent variables is unrealistic; or when such manipulation of human participants is ethically unacceptable (e.g., delinquency, illnesses, road
accidents, suicide).

A

Causal-Comparative or Ex-Post Facto Research

37
Q
  • “An observable characteristic of an object, event, or people that can be described according to some well-defined classification or measurement scheme”
  • Measurement of something that holds at least two distinct values across participants within the study.
  • A characteristic or attribute that has two or more mutually exclusive values or properties (Ardales, 1992);
A

Variables

38
Q

Variables which can’t be measured numerically/quantitatively

A

Qualitative Variable

38
Q

Functions of variables

A

Presumed causality and Purpose of inquiry

39
Q

Variables which can
be measured numerically

A

Quantitative Variable

40
Q

Independent and Dependent Variable

A

Presumed Causality

40
Q
  • “the factor that is manipulated or controlled by the
    researcher”
  • The one varied during the experiment;
  • Presumed cause of the dependent variable
  • It is what causes or influences the outcome”
  • It predicts the relationships
  • Also referred to as explanatory variable
  • Can be referred to as manipulated, antecedent, stimulus variable
A

Independent variable (X)

40
Q

– the one measured or observed;- The presumed effect of the independent variable.
- The term dependent implies “it is influenced by the independent variable
- Also called criterion, response, consequence, or outcome variables.

A

Dependent variable (Y)

41
Q

_____ are introduced to remove
their influence from the relationship of the other variables

A

Control variables

41
Q

_____ are introduced to further elucidate the nature of the relationships among the variables.

A

Moderator variables

41
Q

Control and Moderator Variable

A

Purpose of inquiry

42
Q

Suspected or known to impact/influence the dependent variable

A

Moderator Variable

42
Q

Any variable that is held
constant in a research study by observing only one of its instances or levels.

A

Control Variable

43
Q
  • factors not considered in the study but which affect/ influences in anyway the study
    variables
  • Variables that are not caused by any other variables in a model of interest
A

Extraneous variable/Exogenous variable

44
Q

Two different scales for
measurement of variables:

A
  • continuous and discrete or categorical
  • nominal, ordinal, interval, or ratio
45
Q

Can take on an ordered set
of numerical values within a certain range.

A

Continuous variable

46
Q

Can take specific values only;
can only have specific value which has
semblance of absoluteness.

A

Discrete variable

47
Q

_____ belongs to nominal measurement

A

Categorical variable

48
Q

Variable that represents two categories

A

Dichotomous variable

48
Q

Variable with many categories

A

Polychotomous variable

48
Q

The application of rules in assigning numbers to cases so as to represent the presence or absence of quantity of an attribute possessed by each case.

A

Measurement

49
Q

SCALES OF MEASUREMENT

A
  • Nominal Scale Measurement (Lowest)
  • Ordinal Scale Measurement
  • Interval Scale Measurement
  • Ratio Scale Measurement (Highest)
50
Q

It is just a descriptive name - no value, no ranking - like colors (red, blue, yellow) or gender (male, female) and are mutually exclusive (for the purposes of the study.

A

Nominal

51
Q

Ranked highest to lowest. Cities
ranked by size of population. Baseball
players ranked by batting average.

A

Ordinal

52
Q

“Continuous variable” in which a number is assigned to the amount of an attribute and IN WHICH ZERO DOES NOT MEAN THE ABSENCE OF THE ATTRIBUTE

A

Interval

53
Q

“Continuous variable” in which a number is assigned to the amount of an attribute and IN WHICH ZERO HAS A MEANING

A

Ratio

54
Q

“Building blocks of hypotheses”

A

Variables
