Q

What level of measurement uses scales, which have equal numerical distances between the intervals. The categories must have equal intervals between them

Ex. Temperature in degrees Fahrenheit changes in temperature can be measured precisely example 70 degrees and 60 degrees has 10 degrees between them.

Q

What level of measurement is the highest form of measurement and meets all the rules of the forms of measurement: mutually exclusive categories, exhaustive categories, ordered ranks, equally spaced intervals, and a continuum of values Rule: the data must have absolute 0

Ex. Group size (5). Weight, length, and volume.,

Example- if you are using a multiple item scale to measure depression, the scale should indicate similar depression scores each time an individual completes it within a short period of time.

Q

Type of observational measurement that the researcher carefully defines what s/he will observe and how the observations are to be made, recorded, and coded as numbers

(Chapter 10)

A

Structured observational measurement

19
Q

Data collection method that involves verbal communication between the researcher and the study participant during which information is provided to the researcher

(Chapter 10)

28
Q

Type of scale used to measure strength, magnitude, or intensity of individuals subjective feelings, sensations, or attitudes about symptoms or situations….

Example: no pain -> worst pain imaginable

(Chapter 10)

A

Visual analog scale VAS

29
Q

is the proportion of patients with the disease who have a positive test result or true positive rate

____________ calculation = probability of disease =
a/(a+c) x100% = true-positive rate

(Chapter 10)

A

Sensitivity

Q

is the proportion of patients without the disease who have a negative test result, or true- negative rate.
