Asking the same question in multiple ways allows researchers to frame analysis in a way that helps them reach the outcome they want. Open-ended surveys are quicker to develop and analyze than close-ended surveys. Survey questions must directly pertain to the overall purposes and research question the researcher has. Not enough people fill out surveys these days, so the researcher must prepare for a very small sample size. Question 7 1 / 1 ptsThe key benefit of a descriptive research design is ______. the ability to gather information based on characteristics, beliefs, perceptions, or attitudes of people to compare group values on qualitative questions to test the effect of one variable on another to assess whether relationships exist between subjects Question 8 1 / 1 pts What is the typical relationship between a research question and a research design? In quantitative analysis, the research design comes first, while in qualitative, the research question comes first. Research questions are typically philosophical, so research design helps researchers think of the best way to ask the question. The research question has a direct influence on the research design selected. Research designs are typically decided before the research question is formulated. Question 9 1 / 1 pts Why is the predictability of patterns between scores an important aspect of correlational design?Researchers should study topics that are typically easy to guess and wouldn’t surprise or upset current knowledge. If the researcher can predict the patterns between scores, then the results are inherently valid. The more predictable the patterns of scores between variables, the higher the correlation the researcher will see. When scores converge together, it is a sign of multicollinearity and researchers should avoid such questions. Question 10 1 / 1 pts Why has mailing surveys to potential respondents become less used as a potential survey dissemination method? Response rates were too high and overwhelmed researchers’ abilities to analyze. Dissemination in this format is typically too expensive and increases the researcher and participant workload. Everyone researchers want to study has access to a computer or phone to take online surveys. Researchers have realized that mailing surveys makes them more subject to forgery than online or phone surveys. Question 111 / 1 pts A group of researchers aims to recruit a sample for a study, and ensures that they write their invitation to participate in a way that is accepting of all sorts of people but still emphasizes the need of a specific, precise sample. What ethical practice is this group undertaking? employing bias-free language ensuring sample validity demonstrating collective efficacy using quantitative analyses Question 12 1 / 1 pts In the text, Joanna presented information such as mean, standard deviations, and frequency counts in her project to showcase which students were more likely to complete homework. These quantitative measures about a sample are referred to as ______. misnomers parameters behavior sketches statisticsQuestion 13 1 / 1 pts A researcher is able to collect multiple data points throughout the research phase when their experiment incorporates a ______. cross-sectional sample logistical interference pretest, without a posttest time series component Question 14 1 / 1 pts When the effect of an independent variable depends or differs across the levels of a second independent variable, this is known as a(n) ______. main effect interaction effect causal effect control group Question 15 1 / 1 ptsWhen publishing journal articles on experimental designs, ______ for all dependent variables are reported, and often a correlation matrix is included as well. inferential statistics descriptive statistics independent t-tests analyses of variance procedures Question 16 1 / 1 pts Which threat to internal validity typically occurs when the actual practice of taking an early assessment might influence later assessments’ results? history testing institutionalization instrumentation Question 17 1 / 1 pts In a multiple baseline design, a researcher intentionally incorporates what?multiple A-B sequences effects that could follow the intervention setting manipulations evaluations of the data Question 18 1 / 1 pts What is the key distinguisher in the method behind single participant and group timeseries approaches? the knowledge of the researcher of control or comparison groups the replication of the baseline-to-intervention sequence communication strategies to the public about results the inclusion of an intervention and remediation Question 19 1 / 1 pts Which method, when using randomly assigned and equivalent groups, can help reduce the threat of testing or instrumentation? pretest-posttestlongitudinal analysis with multiple tests pretest-only comparison group design posttest-only control group design Question 20 1 / 1 pts Instrumentation refers to the threat to internal validity that comes from the researcher changing what over time? the measurement or assessment tool their viewpoint on the conclusion the motivation for the study the funding source for the assessment tools Question 21 1 / 1 pts Why do researchers need to gather background information about the sample in quasiexperimental research designs? to control for certain background information that might influence the dependent variable to randomly assign the sample after the factto test for posttest differences to describe the population being examined more accurately Question 22 1 / 1 pts Why are comparison groups typically preferred over control groups in the case of inschool research? Comparison groups are usually more like the intervention group. It is seen as unfair by parents and administrators to give one group an intervention and another group no alternative service. Schools must uphold higher standards of research studies than other locations. Control groups typically cost money, whereas comparison groups do not, which is appealing to many modern schools. Question 23 1 / 1 pts Why would a researcher be uninterested in internal validity of their experiment? There has been no observable change or effect observed. Theory backs up the researcher’s perspective. A professional journal has published an article that has come to the same conclusion.The researcher feels very confident that they have the right answer. Question 24 1 / 1 pts Dr. Johnson wants to see if sending a funny email to his students midway through the class will make students pay more attention. He has students draw cards that either have a number one or a number two printed on them and sends the email to everyone who draws the number one. What practice did Dr. Johnson use? situated reasoning internal correspondence time-series effect random assignment Question 25 1 / 1 pts Aryn is running an experiment where she has randomly assigned participants to a treatment and a control. What type of experiment is she running? single-group pretest-posttest design naturalistic study true experimentcross-sectional analysis Quiz Score: 25 out of 25
