Q

In single case study, that studies at once, following a treatment or an agent presumed to cause change.

37
Q

Two kinds of Quantitative (numerical) Variables

A

> Discrete variable
Continuous Variable

38
Q

-Can assume only a finite or countable number of distinct possible values
-Value is obtained by counting.
-example: class size, tickets sold, number of errors in a quiz

A

DISCRETE VARIABLE

39
Q

-Can take any value in either a finite or infinite range
-Value is obtained by measuring
-example: Interest rate in %, weight in kg, volume in liters, time to complete an exam

A

CONTINUOUS VARIABLE

40
Q

Scale (levels) of measurement

A

-Nominal or categorical scale
-Binary variable

A

Nominal or Categorical Scale

42
Q

nominal variable having just two possible categories (e.g. presence or absence of pain)

A

Binary variable

43
Q

-Numbers are assigned to objects to indicate the relative extent to which the objects possess some characteristic.
-It allows you to determine whether an object has more or less but not how much more or less
-ex: Likert scale: 1-strongly agree, 2-agree, 3-neutral, 4-disgree, 5-strongly disagree

A

Ordinal or Ranking Scale

44
Q

-Numerically equal distances on the scale represent values in characteristic being measured.

compare two or more characteristics or attributes of two or more persons, group, institutions, or phenomenon.

describes the coverage of the study. It specifies what is covered in
terms of concept, number of subjects or the population included in the study, as well as the timeline when the study was
conducted.

Scope

74
Q

composed of written indicators and data elements of the coverage, limitations, and its context to build the integrity of a research project.

75
Q

are citing factors or variables that are not to be included and the boundary in terms of time frame, number of subjects, participants or respondents who are excluded. Specify that which you will not deal within the study. Normally under control of the researcher. Formulating Research questions delimits the research topic to specific area
