People with more referrals are more likely to be hired. What type of correlation is this? - Answer Positive A researcher wants to determine how socioeconomic status (SES) influences delay of gratification. Participants are matched on all variables but their SES and sorted into three groups: low SES, middle SES, and high SES. Then they're exposed to the delay of gratification procedure. What type of research design is this? - Answer Ex post facto Calvin wants to know how people with ...

Completely Randomized Design correct answer: An experimental design where all experimental units are randomly assigned treatments. Randomized Block Design correct answer: An experimental design in which the experimental units are placed into homogeneous groups. The random assignment of the units to the treatments is carried out separately within each block. Matched Pairs Design correct answer: An experimental design in which each subject receives both treatments in a random order or sub...

lab experiment - These take place in a situation or environment that is artificial to the participants in the study. There are two main types of variable that need to be considered when running any experiment. strengths of lab study - have high levels of standardisation and so can be replicated to test for reliability. As laboratory experiments have high levels of control, researchers can be more confident it is the IV directly affecting the DV. weaknesses of lab study - As labor...

Research Methods - Experiments, Self-reports, Case studies, Observations, Correlation Experiment - An investigation in which a hypothesis is scientifically tested. (Lab, Field, and Natural) Self-Reports - Any test, measure, or survey that relies on the individual's own report of their symptoms, behaviors, beliefs, or attitudes. (In1terviews and questionaires) Case Studies - The inverstigation on one individual person. Observations - Any test, measure, or survey that r...

AP Statistics Inference for Regression (CONDITIONS) - correct answer Linear: True relationship between the variables is linear. Independent: observations, 10% condition if sampling without replacement. Normal: Responses vary normally around the regression line for all x-values Equal Variance: around the regression line for all x-values Random: Data from a random sample or randomized experiment Paired t-test: Phrasing Hints, H0 and Ha, Conclusion - correct answer Key Phrase: MEAN DIFFER...

A trainer is studying the effects of vitamin D on his athletes. He has realized that there are many potential confounding factors, such as gender and age. To limit the effect of these confounding variables, he decided to first group two athletes together based on these variables (for example, two 21-year-old males). Then he randomly assigned one person to receive the vitamin D and the other to receive a sugar pill. What type of experimental design does this situation demonstrate? Complete...

Experiment - Investigation looking for a causal relationship in which an IV is manipulated and is expected to be responsible for changes in the DV. Independent Variable - Factor under investigation in an experiment which is manipulated to create two or more conditions or levels and is expected to be responsible for changes in the DV. Dependent Variable - Factor in an experiment which is measured and is expected to change under the influence of the IV. Extraneous Variable - E...
