Flashcards in Chapter 4 Terms Deck (39)
A set of advance decisions that makes up the master plan specifying the methods and procedures for collecting and analyzing the needed info.
Most commonly unstructured, informal research that is undertaken to gain background information about the general nature of the research problem.
Secondary data analysis
The process of searching for and interpreting existing information relevant to the research topic.
Gathering info from those thought to be knowledgable on the issues relevant to the research problem.
AKA: key-information technique
Used to acquire information from lead users of new technology.
Review of available information about a former situation that has some similarities to the current research problem.
Small groups brought together and guided by a moderator through an unstructured, spontaneous discussion for the purpose of gaining info relevant to the research problem.
Undertaken to describe answers to questions of who, what, where, when, how...
Measure units from a sample of the population at only one point in time.
Cross-sectional studies whose samples are drawn so that they are representative of a specific population.
Repeatedly measure the same sample units of a population over a period of time.
Represent sample units who have agreed to answer questions at periodic intervals.
Continuous Panels & Discontinuous Panels
Continuous panels ask panel members the same questions on each panel measurement.
Discontinuous panels vary question from one panel measurement to the next.
Including or covering many things or classes (Discontinuous...)
How many people switched brands...
Market tracking studies
Measure some variable(s) of interest (market share or unit sales) over time.
Understanding a phenomenon in terms of conditional statements of the form "If x, then y".
Manipulating an independent variable to see how it affects a dependent variable, while also controlling the effects of additional extraneous variables.
Variables over which the researcher has control and wishes to manipulate.
Variables over which we have little or no direct control but a strong interest in changing.
May have some effect on a dependent variable but yet are not independent variables.
A procedure for devising an experimental setting so that a change in a dependent variable may be attributed solely to the change in an independent variable.
When a measurement of the dependent variable is taken prior to changing the independent variable.
When a measurement of the dependent variable is taken after changing the independent variable.
"True" experimental design
isolates the effects of the independent variable on the dependent variable while controlling for effects of any extraneous variables.
Designs that do not properly control for the effects of extraneous variables on our dependent variable.
A group whose subjects have not been exposed to the change in the independent variable.
Group that has been exposed to a change in the independent variable.
Before-after control group
Randomly dividing subjects of the experiment into two groups -- control & experimental...
