Q

In some cases is it unethical to complete a single subject design?

A

Yes, as it allows to withdraw treatment and if patient is at risk for harm this could be a problem.

Q

did the experimental treatments make a difference in this instance?

A

internal validity

21
Q

this describes the data

A

descriptive statistics

22
Q

generalizations are made about a population by studying a subset or sample

A

inferential statistics

ANOVA, t-test, chi square

23
Q

test of statistical significance difference between sample means

A

t-test

24
Q

test of statistical significance that measures the difference between observed frequencies and expected frequencies due to chance. Values less that .05 are statistically signifiant

A

chi square

25
Q

This scale categories have logical order and are scaled according to the amount of the particular characteristic they posess

A

ordinal scale

ordering football teams according to number of games won, arranging students according to height

26
Q

This scale classifies objects into catagories

A

nominal scale

27
Q

this scale allows differences between various levels of the categories on any part of the scale to have the same differences. Zero=is just another point of the scale

A

Interval scale

Fahrenheight

28
Q

equal differences in the characteristic are represented by equal differences in the number assigned to the categories. Zero= absence of the characteristic.

A

Ratio scale

miles per hour, weight, length

29
Q

Each individual within a population has an equal chance of being selected for the study and all members of the sample or selected independently of one another

A

Random sampling

30
Q

True or False: True experiments must have random assignment of subjects

A

True

31
Q

Occurs when individuals selected for the study are assigned to experimental or control groups according to chance

A

random assignment

32
Q

This results from the collection of evidence in such a way that one alternative answer to a question is favored over another.

A

Bias

33
Q

True or False: in test administration bias occurs when experimenters administer the test differently.

A

True

34
Q

no difference or no relationship between the variables tested

A

null hypothosis

35
Q

probability that difference is due to chance

p> .05

A

level of significance; statistical significance

36
Q

This type of research examines previous methods which helps to design interventions they want to test.

A

developmental research

37
Q

Thomas believes ______________________ may be the single most appropriate model of research for SW as it uses methods directed explicitly towards analysis, development and evaluation of the means by which SW objectives are achieved.

A

Devlopmental research

38
Q

True or False It is important for a SW to know the stages of research in order to determine credibility of research and how to evaluate each stage.

A

True

39
Q
  1. Problem formulation
  2. Research measurement design
  3. Data analysis
A

stages of research process

40
Q 
problem statement
definition of concepts
specification of hypotheses
statement of assumptions
These all need to be clarified under what stage of research?
A

Problem formulation

41
Q

This type of research seeks to describe actual events as they occur. They look at observations and/or interviews.

A

Qualitative: it is difficult to show reliability and validity in this type of research.

42
Q

This research design focuses on a number of people (family, larger systems) how have experienced a similar event.

A

Group design

43
Q

This type of design looks at an individual person/event and can follow the scientific method.

A

single case design

44
Q

This type of design is used when very little is known about the subject

A

exploratory design

45
Q

This design must have an independent variable, other variables are measured so that their effects can be accounted for or that such variables are the same in all subjects. The subjects must be randomly selected

A

explanatory design

46
Q

The task of the _________ is to select a design that is appropriate for the hypotheses that was proposed and that all results occur as a result of the experimental manipulation rather than a result of other events

A

researcher

47
Q

This is used to determine what the relationship is likely to be among several variables

A

inferential statistics

48
Q
  1. how to collect data
  2. what instrument to use
    3 how to code and analyze data
    4 how to relate the data to the original problem
    These are questions relating to __________?
A

research measurement design
