Question 442 pts
One of the major reasons why single-case studies are called single-case experiments is because they:
Group of answer choices
involve the manipulation of only one independent variable.
allow researchers to determine the effect of the treatment on one participant.
involve a set of observations for one dependent variable.
allow researchers to compare the outcomes for one treatment participant and one control participant.

Question 322 pts One of the major disadvantages of studies with switching replication with treatment removal is that they still cannot determine if: Group of answer choices the control group changed in response to the treatment. experimenter expectancy effects or demand characteristics played a role in the results. differential history is a problem. the treatment will have an effect even after it is removed.
Question 332 pts One of the major reasons why program evaluators do not use better study designs such as true experiments is: Group of answer choices that they often cannot convince stakeholders of the importance of rigorous scientific methods. time and funding constraints. because advanced study designs are unnecessary in basic research. the lack of scientific knowledge on the part of evaluators.
One of the major learning objectives of this chapter is to define a factorial research design, including the terms factor and level, and to identify and describe factorial designs when they appear in a research report. The goal of experiments is to establish the existence of a cause-and-effect relationship between two variables. To accomplish this goal, the researcher manipulates one variable (that is, the independent variable) and measures a second variable. Nonexperiments and quasi-experiments are similar to experiments except that...
Key Terms ---------------------------------------------------------------------------------------------------------------------------- Descriptive statistics --- The area of statistics concerned with organizing and summarizing information about a collection of actual observations. Inferential statistics --- The area of statistics concerned with generalizing beyond actual observations. Data --- A collection of observations from a survey or experiment.

Qualitative data --- A set of observations where any single observation is a...
Question 13 A major company would like to assess the impact of using a professional trainer to conduct a confidence-building workshop with their salespeople. A sample of 16 workers is obtained. Half (n = 8) are randomly assigned to attend the workshop and the other half (n = 8) serves as a control group. Two weeks later, each of the participants is given a questionnaire measuring the level of self-confidence. Please choose the statistical test that is most appropriate for...
Questions 33-35. Based on the vignette below, answer the following questions. Vignette II. You become very interested in the large public interest in the iPhone. You decide to use the experimental method so you can try to understand the causes of fascination with the iPhone and be able to generalize your results to the larger population beyond the Apple Store employees. You recruit large numbers of participants, a representative sample of the larger population, and ran- domly assign them to...
QUESTION 1 Researchers are interested in the speed of responses people make to different target finding tasks. They state that reaction time is the time in the unit of milliseconds between the presentation of a stimulus, and the keyboard press made by the individual. This is an operational definition of reaction time. True False QUESTION 2 Some researchers are interested in the cognitive limits to the various tasks air traffic controllers perform. They figure the best way to understand these...
Psy 248: STATISTICS- MARIA MIRANDA Computer Lab Assignment II, SP 2019 Comparing means using t-tests This assignment will give you practice choosing the appropriate test statistic to use for different research designs that all involve comparing using t-tests. You will need to enter the data, use SPSS to test hypothesis, and write a conclusion for each problem stating weather or not the samples differed significantly. To run all 3 tests, use: ANALYZE, COMPARE MEANS, and then select the type of...
Case One: Cloud Helps Fight Cancer Each minute one person in the United States dies from cancer—over half a million deaths per year. Thousands of scientists and physicians are working around the clock to fight cancer where it starts—in our DNA. DNA is a molecule present in our cells that carries most of the genetic instructions used in the development, functioning, and reproduction of all known living organisms. The information in DNA is stored as a code made up of...
Question: for the following article please specify the following: What is/are independent variable(s)? (Specify the levels) What is/are dependent variable(s)? (List all dependent variables authors measured) Of Blood and Death: A Test of Dual- Existential Systems in the Context of Prosocial Intentions Blood donation is an important expression of prosocial behavior in modern society. The extent to which thinking about death increases intentions to donate blood is the focus of the experiment reported in this article. The dual-existential-systems model (Cozzolino,...
