Research And Stats Flashcards
Basic steps for using research (5)
Form pico question
review evidence
Determine validity, reliability and applicability of research study.
Determine usefulness and support of the info as it pertains to your question.
Bese treatment on evidence
Case control study vs case study?
Case control study looks at 2* groups of people. Case study looks at one person, 1* group of people or one issue.
A comparison of two or more variables that change in relation to each other.
Covariation
if the p value is .05 or LESS, the null hypothesis is?
Rejected.
The extent to which an assessment tool measures what it is supposed to measure.
Validity
The determination of how well an assessment tool measures an outcome.
Criterion validity
The determination of how well an assessment tool measures an attribute or skill that it claims to measure.
Construct Validity
The ability to duplicate the results of an assessment: does the test provide the same results if administered under the same conditions.
reliability
An inductive method of research in which the data is collected first is?
Grounded Theory
A study in which the effects of an independent variable on a dependent variable are examined. This type of study does not include random assignment of subjects to experimental or control groups. Subjects are limited to a specific population, such as patients with Parkinson’s Disease or children with Down Syndrome. Subjects are usually selected by convenience, such as patients who attend a community based mental health program. Random assignment to experimental and control groups is not possible due to small sample sizes or the nature of the variables studied.
Quasi-experimental
A study on the use of weighted vests with children with autism. What kind of study?
Quasi-experimental
A study in which manipulation of the independent variable is not possible. Randomization and researcher control are also not possible.
non-experimental or correlational
99% – z score =
2.576
Levels of measurement: –Also called qualitative type, as classifications are usually qualitative. Gender, ethnicity, language, genre, style, biological species.
Nominal type
Levels of measurement: – Places data in rank order but does not determine the degree of difference between data sets.
Ordinal type
