Research Types
A researcher analyzes open-ended interview questions to determine themes.
What is qualitative research?
The gold standard in research that uses randomization and control groups.
What is a random clinical/controlled trial (RCT)?
The statistic that is also called an effect size
What is a Cohen d?
When test or research results are consistent.
What is reliability?
The variable that the researcher manipulates in an experimental design.
What is the independent variable?
A researcher analyzes pre-and-post test scores
What is quantitative research?
The lowest level of evidence on the evidence-based practice continuum.
What is expert opinion?
What is a percentile?
The degree to which a new test is correlates with an established test.
Concurrent validity
What we call it when treatment results in improvement derived from treatment not extraneous factors, is reproducible, and is clinically important.
Efficacy
A researcher advertises for people with a communication disorder to participate in a study to add to the knowledge in the field.
What is basic research?
A study that uses control groups but does not randomization.
68%
What is the percent of people who fall between +/-1 standard deviation on a bell-shaped/normal curve?
The type of validity which means whether the results can be generalized.
External validity
What is a large effect size?
A researcher analyzes existing data to determine if therapy has been effective?
What is retrospective or archival data research?
A study that does not use randomization or control groups.
What is pre-experimental designs?
85-115
What is the normal range for tests with a mean of 100 and a standard deviation of 15?
The type of validity that means the change in the dependent variable is due to the independent variable and not extraneous variables.
Internal validity
A distribution curve that has two peaks.
What is a bimodal distribution?
An SLP conducts a research study to determine if a new approach is effective using his/her own clients as participants.
What is applied research?
RO X O
RO O
What is an RCT or Random Clinical/Controlled Trial?
The range of possible scores for a correlation.
What is + or - 1?
A threat to validity because the subjects' behaviors are affected their knowledge that they are in a study.
What is the Hawthorne Effect?
A research study that reviews all the existing research on a therapy approach and combines the data from the studies to calculate an effect size.
What is a meta-analysis?
