Definition
| 4 key elements, baseline, intervention, data collection and data analysis |
|
|
Term
|
Definition
| sigle system design, contains baseline, monitoring during intervention and followup or intervention is over. not recomended for most practice situations, good for groups cuz groups end, the 2nd "A" is never a 2nd baseline |

|
|
Term
|
Definition
| used when you are working with several clients who have the same problem and recieve same intervention. this design is used on multiple ppl but only when the first shows signs of inprovement can u move onto the second and they show improvement the 3rd, and so on. |

Term
|
Definition

|
|
Term
| How is internal validity different from external validity? |
|
Definition
| internal validity is something you attempt to control in your research(age, sex, gender, etc), external is something you have no control over. |
|
|
Term
| What are common independent variables and what makes them independent? |
|
Definition
| Common independent variables are things such as age, gender, race. The are independent becausethey can be controlled, and they are suspected to change the event of situation you are studying. |
|
|
Term
| What could be two dependent variables and why would it be a dependent variable? |
|
Definition
| a dependent variable is the topic of your investigation. an example would be juvenile deliquency or adult alcoholism |
|
|
Term
| why is the line between the dots in a single subject design important? |
|
Definition
| because it shows if the intervention is working |
|
|
Term
| describe two threats to internal validity and why they are important? |
|
Definition
| 1. selection of respondants (any biases that the control or experimental group may have that may be different from each other or the larger population. instrumentation, a change in the measuring or procedures used |
|
|
Term
| what is a scale and why is it important? |
|
Definition
| a scale is a group of questions designed to measure a single idea. it is important because, it can be developed to measure different kinds of problems or concepts, |
|

Term
| 7 steps in the research project |
|
Definition
| The seven steps in a research project are, Hypotheses, reviewing the literature(seeing what has already been done), developing a research design, operationalizing, collecting the data, analzing the data, and writing the report. |
|
|
Term
an example of a hypothesis would be:
the dependent and independent variables are: |
|
Definition
| Adults with a bachelor's degree, are less likely to be an alcoholic than those who do not have a bachelor's degree. Independent variable= Adults with a bachelor's degree, dependent variable=less likely to be an alcoholic |
|
|
Term
| What is the "hypothesis" and why is it important to research design? |
|
Definition
| the hypothesis is a statement about something you are going to research. It is important because it commits to an idea |
|
|
Term
| what is research design and why is it important? |
|
Definition

|
Definition
| internal validity is variables you attempt to control |
|
|
Term
| when should we use single subject design? |
|
Definition
| use single system designs to determine if a particular intervention is working it shows the clients progress. |
|
|
Term
| how is a single system design done? |
|
Definition
| chose a behavior you want to monitor, obtain a baseline, introduce the intervention and monitor |
|
|
Term
|
Definition
| making positive correlations between the test you gave and an outside source (someone else's simiiliar test/data) |

|
|
Term

Term
| What are the threats to internal validity? |
|
Definition
| maturation, history, testing instrumentation, selection of respondents, statistic regression, mortality, interaction effects, |
|
|
Term
| why are the threats to internal validity important? |
|
Definition
| studies with better internal validity allow researcher to rule out alt explanations and other hypotheses. |
