Q

To establish the measure as having good reliability, it should have…

A

High reliability coefficient and a low standard of error

28
Q

If a researcher is analyzing data collected during his research study and has found that p<.05, he may decide to reject the…

A

null hypothesis

29
Q

Refers to how well a test detects a condition that is actually present.

A

test sensitivity

30
Q

In ___ procedures there is a normal distribution of data.

A

parametric statistical

31
Q

Any factor that is NOT directly related to the purpose of the study but may affect the dependent variable. When these factors are not controlled, they exert a confounding influence on the independent variable, that is they contaminate the independent variable in such a way that their separate effects are obscured.

A

Extraneous Variable/Confounding factor

32
Q

Study with adhesive capsulitis, patient was taking pain meds and did NOT disclose this. This is an example of a(n)

A

Extraneous Variable/Confounding factor

33
Q

Statistical procedure appropriate for comparison of three or more treatment groups or conditions, or the simultaneous manipulation of 2 or more independent variables

A

ANOVA

34
Q

ANOVA is the best measure to use when utilizing.

A

Simultaneous Comparison of several means

35
Q

Refers to how well the measure reflects a theoretical construct of the characteristic of interest.

A

construct validity

36
Q

Refers to how well the test items measure the characteristics or behaviors of interest.

A

content validity

37
Q

Refers to test stimuli, methods, or procedures reflecting the assumptions that all populations have the same life experiences and have learned similar concepts and vocabulary.

A

content bias

38
Q

A parametric test for comparing 2 means (for example this test is used when there is a single dependent variable, but a comparison between groups)

A

t-test

39
Q

Best means of analysis to use when you have a study of a new treatment technique but have 2 groups – one participating for 30 minutes a day and one group participating for 60 minutes a day. This is an example of…

Q

The Collaborative Institutional Training Initiative and is dedicated to promoting the public’s trust in the research enterprise.

A

CITI

41
Q

Three categories of qualitative research:

A

Experimental
Descriptive
Mixed Experimental-Descriptive research

42
Q

The average amount that all scores in the distribution deviate from the mean. A small standard deviation indicates more homogeneity.

A

standard deviation

43
Q

In ___ procedures there is a normal distribution of data

A

parametric

44
Q

In ___ procedures- there is not a normal distribution of data

A

nonparametric

45
Q

The ___ just means the probability of the findings. For example, if the value is p<.05, that means the probability of that finding being true is 95% and the probability of the finding being false is 5%. And if we say that p<.01 that just means the probability of the findings being true are 99% and only 1% chance of the findings being incorrect. That is a very brief explanation of statistical findings.

A

p-value

A

ANCOVA

62
Q

Refers to how well the measure correlates with an outside criterion.

A

criterion validity

63
Q

Estimates can help the OT to understand the practical significance of data in a research study. Rather than reflecting whether the null hypothesis is false, the effect size estimates the degree to which it is false.
