4Angelo is studying the effects of reward magnitude on children learning spelling words using a within-subjects design. Children get paid either $0.50 or $1 for every word they spell correctly on their weekly spelling tests, and the outcome measure is the number of words spelled correctly, a ratio level measure. what tests would be used with the types of design and data?

5Lois is studying the effectiveness of three different stress-reducing apps using a within-subjects design. Her outcome measure is the severity of stress reported by participants, an interval level measure.

8There are occasions when a researcher must examine preexisting groups. For example, a researcher may want to compare student performance for a high school that encourages students to use their phones and tablets during class with student performance in a high school that bans the use of electronic devices. In this study, the researcher does not have control over which individuals are assigned to which group; the two groups of participants already exist. Because the researcher cannot use random assignment or matching to minimize the individual differences between groups, there is no assurance that the two groups are equivalent. In this situation, the research study is called a
- Anonequivalent group design
- Bequivalent group design

- Cposttest-only nonequivalent control group design
10Colleen is interested in preventing adolescents from ever starting to use tobacco. She has the opportunity to work with two health classes at a middle school.

- Apost test only
- BPre-test post-test nonequivelent control group design
- Cdifferential
11Julie is contacted by a community-based organization that needs to evaluate a self-esteem building intervention it has created for use in its after-school program. Unfortunately, the program has already begun, so Julie arranges to measure the children’s self-esteem after the intervention has been completed and compares this data to measures of self-esteem she gets from another after-school program where the children have not gotten the self-esteem building intervention.
what type of design ?- ADifferential
- BPost Test only

14Identify the design Emmett works with adults with severe persistent mental illness. He is well aware that, because of their illnesses, their self-esteem can vary substantially from time to time. He has developed an app that he believes will help maintain some stability in their self-esteem. In order to have more stability in his measurements, he measures self-esteem on a biweekly basis, starting a month before he gives the research participants access to the app, and then measures self-esteem biweekly for another six weeks.
- ATime series
- Bpre test post test
- Cinterrupted time series design
15Elaine studies the effects of natural disasters. After a February blizzard shuts down a large part of the state, many newscasters speculate about a baby boom the following November. Elaine decides to look at birthrates in September, October, November, December, and January to find out whether there is, indeed, a boom of blizzard babies.
Identify the design- Apre test post test
- Binterrupted time series
- Ctime series
16Developmental research designs are another type of nonexperimental research that can be used to study changes in behavior that relate to age. The purpose of developmental research designs is to describe the relationship between age and other variables.

- Blongitudinal developmental research design
17what research design examines development by observing or measuring a group of cohorts over time.
- Alongitudinal
- Bobservational study
- Cfield study

21How can factorial designs correctly address specific research issues? Check all that apply.
- AIf a researcher is concerned about treatment order effects, treatment order can be used as a factor.
- BIf a researcher using a within-subjects design suspects that a particular participant characteristic, like age, may affect the outcome of treatment, that participant characteristic can be used as a factor.
22Rhonda is studying the effects of hunger on academic performance. She uses hunger as a within-subjects factor, starting her subjects out with a very small breakfast and testing them at two-hour intervals throughout the day without any additional meals or snacks.

- DSingle-subject designs generalize well to other subjects and other settings
- ESingle-subject designs tend to be rather rigid.
32By showing that the pattern of behavior in each treatment phase is clearly different from the pattern in each baseline phase, the researcher demonstrates the presence of [blank_start]arelationship[blank_end] Correct between the treatment and the behavior change. By demonstrating that the changes in behavior from baseline to treatment and from treatment to baseline are the same for each of the phase-change points in the experiment, the researcher demonstrates the presence of [blank_start]acausal relationship[blank_end] Correct between the treatment and the behavior change.
- Arelationship
- Bcausal relationship
