62
Q

operationalization

is the development of specific research procedures (operations) that will result in empirical observations representing those concepts in the real world

63
Q

conceptions

mental images of what a specific word means in your mind from what you were told it means and your experience

64
Q

Concept

A
  • The result of coming to an agreement about what the conceptions mean
65
Q

indicators

an observation that we choose to consider as a reflection of a variable we wish to study. Thus, for example, hugging someone who is crying might be an indicator of social support (ch. 6)

66
Q

dimension

A

a specifiable aspect or facet of a concept (ch. 6)

if several different indicators all represent, to some degree, the same concept, then all of them will behave the same way that the concept would be have if it were real and could be observed

68
Q

nominal measures

A
  • variables with attributes that have only characteristics of exhaustiveness and mutual exclusiveness are being measured at the nominal level
  • nominal measures merely offer names or labels for characteristics
  • ex: email-server, birth place, hair color, college major
69
Q

ordinal level

A
  • a level of measurement describing a variable with attributes you can rank-order along some dimension (ch 6)
  • variables with attributes we can logically rank-order are being measured at the ordinal level
  • ex: socio-economic status as composed of high, medium, and low
70
Q

interval level

A
  • a level of measurement describing a varibale whose attributes are rank-ordered and have equal distances between adjacent attributes.
  • The Fahrenheit temperature scale is an example of this, since the distance between 17 and 18 is the same as that between 89 and 90. (ch. 6)
  • the actual distance separating those attributes matter - such variables are being measured at the interval level
71
Q

ratio level

A
  • a level of measurement describing a variable the attributes of which have all the qualities of nominal, ordinal, and interval measures and are also based on a “true zero” point. Age is an example of a ratio measure (ch. 6)

74
Q

Alternate-Form Method

A
  • this technique requires a researcher to develop two different forms or versions of the same measure from the same pool of measurement items.
  • the same, or similar, scores will be derived for subgroups measured with each form
75
Q

Internal Consistency Method: split-half reliability

A
  • a kind of internal consistency measurement of reliability in which the scores from two halves of a given measure are correlated for a group of participants
  • for example: odd-numbered items and even-numbered items on a survey measure
76
Q

Internal Consistency Method

A

based on the assumption that the various items in a given measure should correlate positively with one another. in other words they should perform consistently.

77
Q

Internal Consistency Method: item-total reliability

A
  • a kind of internal consistency measurement reliability in which the score on a given item is compared to the total score.
  • if all of the items correlate positively with the total score, then the measure is said to have high item-toatl reliability

  • three types: face validity, expert panel validity, criterion validity
80
Q

81
Q

expert panel validity

A
  • a form of content validity in which a group of experts with knowledge of a given variable determine whether a given measure taps the full scope of the variable (ch. 6)
82
Q

criterion validity

A
  • a way in which measurement validity is determined
  • the researcher compares a given measure to a criterion variable in which of the two ways:
  • predictive validity (measure must demonstrate that it predicts future behavior) or
  • concurrent validity (one measure of a given variable is compared to a second, established measure of the same variable) (ch. 6)
83
Q

construct validity

A
  • based on the logical relationships among variables
  • convergent validity: a researcher demonstrates that the measure converges, or correlates positively, with measures of theoretically related variables
  • discriminant construct validity: the measure diverge from, or correlates negatively with, measures of theoretically different variables
