What was researcher L studying in a field experiment?
Researcher L was studying preparedness for natural disasters in a field experiment when a particularly destructive hurricane hit a neighboring state. What problem is likely to occur when establishing internal validity in L's research? How are experimental groups different form the control group? What are comparison groups?
What is an example of an experiment in psychology?
For example, in an experiment in which subjects go to a special location for a treatment, something in that location unrelated to the treatment might influence these subjects. This outcome may not have been seen before the event occurred.
What do you call a group of participants receiving a treatment?
The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment).
Which group receives the experimental treatment condition?
experimental groupAn experimental group receives the experimental treatment. A control group does not receive the experimental treatment condition. The standard in experimental research is to compare an experimental group with a control group. However, sometimes two experimental or comparison groups are compared with each other.
What is the term for the recipient of treatment in the research study?
Participant: also known as a "human subject", a person who volunteers to be in a research experiment.
What is the name of the group that does not receive the experimental treatment?
A control group is tested but does not receive treatment. An experimental design in which the effects of order are controlled by having all groups recieve all treatments, but in different order. A variable that is a consequence of or dependent on an antecedent (independent) variable.
What is controlled group?
The control group is composed of participants who do not receive the experimental treatment. When conducting an experiment, these people are randomly assigned to be in this group. They also closely resemble the participants who are in the experimental group or the individuals who receive the treatment.
What is test group and control group?
Specifically, control groups are the customers you are targeting with a particular campaign who will not receive that campaign. The counterpart of control groups is test groups which are the customers you are targeting that will receive that specific campaign.
What is respondents in research?
Respondents are those individuals who complete a survey or interview for the researcher, or who provide data to be analyzed for the research study. Respondents can be any age, but determined by the scope of the study, and must agree to informed consent to participate.
What is a research group called?
A research group (also sometimes called a research centre) is a group of researchers from the same faculty working together on a particular issue or topic. Research groups may be composed of researchers all from the same school/subject or from different subjects within a faculty.
What is treatment in an experiment?
In experiments, a treatment is something that researchers administer to experimental units.
What is the independent group in an experiment?
Independent groups design is an experimental design where different participants are used in each condition of the experiment.
What is controlled group in research?
In experimental designs, a control group is the "untreated" group with which an experimental group (or treatment group) is contrasted. It consists of units of study that did not receive the treatment whose effect is under investigation.
What is the control group in an experiment example?
For example, let's say you wanted to know if Gatorade increased athletic performance. Your experimental group would be given the Gatorade and your control group would be given regular water. The conditions must be exactly the same for all members in the experiment.
What is the term for a researcher who matches up individuals in a treatment group with those in a comparison group?
T or F. Matching is when a researcher matches up individuals in a treatment group with those in a comparison group based on characteristics such as gender, race, and age.
What is an experimental group?
Experimental group - the group of subjects in an experiment that receives the treatment or experimental manipulation; control group - a comparison group that receives no treatment; comparison group - a group that has been exposed to a different treatment (or value of the independent variable) than the experimental group.
How do experiments provide evidence of association?
Experiments can provide unambiguous evidence of association by comparing the distribution of the dependent variable between the experimental and comparison group; in experiments with random assignment of a subject to the experimental and comparison groups, time order can be established by comparison of posttest scores only; The random assignment of subjects to experimental and comparison groups controls for spuriousness; the features of a true experiment do not in themselves allow identification of causal mechanisms; control over conditions is more feasible in many experimental designs than it is in nonexperimental designs.
What is randomization in science?
Randomization - the random assignment of cases, as by the toss of a coin for example; Randomization increases validity since it reduces the risk of spuriousness; matching - a procedure for equating the characteristics of individuals in different comparison groups in an experiment; Matching may effect validity since unmatched characteristics may influence outcomes; combining the two approaches reduces the possibility of differences due to chance
What does a researcher discover about students?
A researcher discovers that the students she is observing have been getting better grades in their classes. The teacher informs her that their grades began to improve the first week the researcher was present. This could be an example of:
When is a Solomon Four Group design best employed?
T or F. A Solomon Four Group design is best employed if a researcher suspects that the pretest will change how subjects respond to the experimental treatment.
What does "d" mean in a scientific statement?
d. decide whether or not the hypothesis was supported.
Why does descriptive research not prove causality?
d. experimental. the researcher cannot control events or manipulate variables. The primary reason descriptive/correlational research does not prove causality is because in conducting the research, a. the data collected frequently come from direct observations or statements made by subjects.
What is data collected frequently?
a. the data collected frequently come from direct observations or statements made by subjects.
What chapter do you study experimental research?
Start studying Chapter 10 Experimental Research. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
What is the purpose of employing subjects for an experiment who are as alike as possible in regard to relevant characteristics?
employing subjects for an experiment who are as alike as possible in regard to relevant characteristics to reduce the influence of extraneous variables.
What is a plan for an experiment?
plan for an experiment that specifies what independent variables will be applied, the number of levels of each, how subjects are assigned to groups, and the dependent variable
When is internal validity threatened in quantitative research?
threat to internal validity in quantitative research occurring when there are important differences between the experimental and control groups before the experiment begins.
What is a group of people called that are asked to complete questionnaires about their thoughts, feelings, and behaviors?
survey. a group of people (called the sample) are asked to complete questionnaires about their thoughts, feelings, and behaviors is considered [ ] research. Pseudoscience. consists of studies (sometimes covering an area of true scientific interest) that do not rely on the scientific method but claim to be scientific.
What is the scientific method?
scientific method. if someone is using theories to develop hypothesis and then testing those hypothesis, that person is using the [ ] naturalistic observation. [ ] [ ] is a type of study in which the researcher unobtrusively observes and records behavior in the real world.
What is the science of plants and animals?
