BUS101 Quiz 6: Research methods for primary data: Part two - experimental research
A researcher is examining the impact of pictures in advertisements and whether including instructions to imagine impact subjects' mental imagery. She manipulated three treatment levels of pictures: concrete picture , abstract picture, or no picture. Instructions to imagine were either present or not present. How many cells are there in this experiment?
6
Categorical variables included in the statistical analysis of experimental data as a way of statistically controlling or accounting for variance due to that variable are called ______ variables
Blocking
A confound is an experimental deception involving a false treatment. True or False?
FALSE
A control group is one in which an experimental treatment is administered. True or False?
FALSE
A response interval is the amount of time it takes to make a choice between two alternatives. True or False?
FALSE
Administering multiple experimental treatment levels to each subject is a way to reduce demand characteristics. True or False?
FALSE
Attitudes can be observed. True or False?
FALSE
Between-subjects designs involve repeated measures because with each treatment the same subject is measured. True or False?
FALSE
In an experiment, the researcher manipulates the dependent variable and measures its effect on the independent variable. True or False?
FALSE
In observation research, a distortion of measurement resulting from the cognitive behaviour or actions of the witnessing observer is called selectivity bias. True or False?
FALSE
It is typical in observation studies for the observer to ask questions of the person who is being observed. True or False?
FALSE
John correctly guessed that the purpose of an experiment he was participating in was to examine the effort of giving employees recognition on his attitude and intention to stay with his company, which creates a confound known as a bias effect. True or False?
FALSE
When the investigator intervenes to create an artificial environment to test a hypothesis, this approach is called artificial observation. True or False?
FALSE
The experimental difference in means between the different levels of any single experiment variable is referred to as a ______
Main effect
Clara is a business researcher who records shoppers' movement through a grocery store. What method of research is Clara using?
Observation
A researcher was observing consumers' facial expressions as they looked over the menu at a restaurant. One consumer forgot her reading glasses, so she was having trouble reading the menu and had to squint her eyes, causing her to look mad. The researcher interpreted this to mean she didn't like what she was seeing on the menu because he didn't know she couldn't see the words. The researcher's misreading the consumer's facial expression as dissatisfaction is an example of _______
Observer bias
Which of the following is a way for a researcher to equally distribute the effects of extraneous variables to all conditions in an experiment?
Randomisation
Monica is conducting an experiment where all subjects rotate through all of the training programs she is testing. This type of experiment in which an individual subject is exposed to more than one level of an experimental treatment is called _____
Repeated measures
John is measuring the amount of time it takes for people to make a choice between two options regarding what to select for lunch to infer the strength of their preferences for one alternative over the other. The recorded choice time is referred to as ______
Response latency
Observing traffic patterns at a busy intersection with cameras is an example of what type of observation?
Spatial relations and locations
A cell refers to a treatment combination within an experiment. True or False?
TRUE
A mortality effect occurs when some subjects withdraw from the experiment before it is completed. True or False?
TRUE
A psychogalvanometer measures galvanic skin response and is based on the assumption that physiological changes, such as increased perspiration, accompany emotional reactions. True or False?
TRUE
The most common procedure to try to ensure that experimental and control groups do not differ from each other in important ways at the beginning of a research study is random assignment of subjects to treatment and control groups. True or False?
TRUE
Observing the comments made by travellers waiting in a check-in line at a Airline ticket counter is an example of what type of observation?
Verbal behaviour
