Research Final

A strength of this self report inventories is ease and time of administration and does not require extensive training

Theoretically, the more control the researchers have over the experimental condition, the lower the internal validity

scores are interpreted based on the comparison of 1 ppt’s prfrmnce w others, all of whom represent a clearly defined pop

Almost every study has limitations.

The accuracy standard addresses whether the information gained addresses the needs of the identified audience

physical/psychological changes that occur in the ppts over the period of the study refer to maturation

The use of convenience sampling is the best solution to the problem of sampling bias

Descriptive statistics describe

Comparison between three types of therapy (narrative, solution-focused, and interpersonal) on grief symptoms- Stats test

Feasibility standards address whether the evaluation is reasonable to conduct

Discussion section-researchers want to relate results to previous research that either supports/refutes prior findings

When experimenter communicates to the ppts most often subtly what outcomes he would like to achieve- disruption effect

The choice of statistical methods is influenced by the purpose of the study.

Readers of research articles do not need to know the specific population the results may be applied to.

Scorer reliability involves the measurement of the consistency of scores over a period of time.

Use of an inappropriate test or dependent measure can result in test bias and problems with interpreting outcomes.

Content validity involves obtaining evidence of prediction of a particular construct

Random assignment to groups increases the effects of some threats to internal validity

______ refers to ensuring the evaluation team has the appropriate credentials and skills to conduct the evaluation.

Random assignment is a helpful strategy to reduce the influence of threats to internal validity within a research design

Assessments that measure heart rate, ECG, blood pressure, and galvanic skin response are known as psychological methods

Criterion-related validity involves obtaining evidence of prediction of a particular construct

What is the key difference between a t-test and an ANOVA?

When evaluating articles in professional lit, any error/ limitation of a study should cause u to reject the findings

As you increase internal validity, external validity typically decreases.

In program evaluation, utility concerns whether the information gained addresses the needs of the identified audience

An insider, someone who works for the organization, may have a good understanding of issues confronting an organization

Strong indicators of internal consistency reliability in a particular test/ measure have an alpha score of at least

Quant research strategies 1st followed by qual research strategies=ex of a mixed methods sequential exploratory design

Randomly selecting classrooms is an example of systematic random sampling.

Hierarchical regression analysis results revealed that the set of predictors you entered had an effect size of R²=.22

Sampling error and sampling bias do not affect the validity of sample selection.

______ principle in evaluation involves clearly disclosing conflicting relationships in roles regarding the evaluation

When ppts become sensitized to intent of the study or desired responses from pretest to posttest- attrition

The conceptual basis for COMPARE studies is an equation examining the ratio of btwn grp diff to within group differences

Internal validity refers to the extent to which researchers can replicate results thus generalize results to the pop

Alternate-form reliability concerns the consistency of a measure based on content.

We can always prove a hypothesis

A university researcher who selects Intro to Psych students as his sample to represent all adults in the pop- Sampling?

when evaluating articles in the professional literature it is important to note any biases in the literature review

Most general type of validity= construct validity, bc it concerns degree to which a test measures intended construct

Qualitative research is presented in the results section in the form of numbers.

Stakeholders are all those who may potentially be affected by the results of an evaluation.  

a comparison between a control group and a group receiving an experimental treatment- which statistical procedure?

threat to internal validity which involves participants dropping out of the study - attrition

selecting a subset of indivs from the accessible pop so that every single indiv has an = chance of being chosen

use an unobtrusive measure, so the ppts are not aware they are being observed or measured on the DV is a solution to..?

When studies are conducted over a period of time and there is no random assignment to groups, history is not a threat.

type of sampling consists of selecting individuals from the population who represent subgroups

W/o info on reliability & validity of the instruments in a quant study=difficult to conclude whether results r accurate

Answer the following analogy: An independent t-test is to a Mann-Whitney U test as a dependent t-test is to a(n):

Events occurring during the time of the study that are unrelated to the treatment or IVs are known as history.

Reliability addresses the degree to which you are actually measuring what you want or intend to measure

Which section of an article provides an argument for conducting the research?

All the potential effects that alter the true score are referred to as "error"

researchers must go beyond the numbers & stats reported and interpret the findings so that they may be of practical app

descriptive statistical methods are employed when certain assumptions about the data collected are violated

When the purpose statement denotes an attempt to determine relationship btwn 2 variables, the study is utilizing a ? aim

The propriety standard concerns the extent to which an evaluation and its results are legally and ethically conducted 

Type of hypothesis?- likely to be a difference in groups but there is not enough evidence to predict the exact direction

In qualitative research reporting results should include providing concrete verbal examples linked to themes or concepts
