E
E-Spread:
The distance between the first and seventh sample eighths.
E-Tailer:
An online retailer that exists only online and does not have a physical store location.
Editing:
A system of checking and verifying that questionnaires were properly completed and accurate to the respondent’s best knowledge.
Efficiency:
The ability of the sample to truly represent a population.
Elasticity:
A measurement that explains the volume of the shift in a single variable as a response to movement of another variable.
Electroencephalogram (EEG):
A device used to measure and record electrical activity in one’s brain.
Electronic Customer Relationship Marketing (eCRM):
The use of CRM to both customers of online companies and to use the Internet as part of a normal company’s CRM program.
Electronic Data Interchange (EDI):
EDI is a well-established form of electronic commerce that has traditionally taken place over proprietary networks. One way of reducing the cost of EDI, and making it more accessible to smaller companies, is to migrate EDI standards to the Internet, various systems are currently competing to offer this service.
Electronic Data Processing (EDP) Systems:
Computer processing that is able to manipulate raw data and uncover relationships with little intrinsic value. Declarative and summary reports can be produced using electronic data processing.
Element Sampling:
Random sampling which gives an equal chance to each unit of a population of being selected.
Enumeration Districts (EDs):
Areas that are defined by the Census and generally contain 500 inhabitants.
Epsem Sample:
A sample that allows each unit the same probability of being selected (with non-zero probabilities).
Equivalent Form Reliability:
A testing method using two similar instruments to obtain the same or very similar measurements of a single object.
Error Checking Routines:
Computer programs that accept instructions from the user to check for logical errors in the data.
Error Sum of Squares:
Any variation that is not known to be caused by regression.
ESOMAR:
ESOMAR is the European based international association of market researchers. Amongst many other activities, ESOMAR issues guidelines on the conduct of market research, and these guidelines are binding on it members. These guidelines include sections on using the Internet for market research.
ESOMAR/ARF Internet Guidelines:
The most important guidelines for researchers using the Internet are those provided by ESOMAR and ARF. These rules include guidance on providing Privacy Policies, of the special rules for interviewing children, and the need to avoid spam. The guidelines can be downloaded from ESOMAR
Estimate:
A value that is projected to a population’s parameter after examining a statistical sample.
Evaluate Research:
A research process used to identify the levels of effectiveness and efficiency in certain programs.
Event (simple):
A sample’s subset. Events that are simple contain only a single outcome as a result of that event. An example would be in rolling a die, only a single outcome is allowed, this set of outcomes consists of six simple events (1,2,3,4,5,6).
Exchange:
Defined as the prefix (first three numbers) of a telephone number. The numbers represent the town, community or neighborhood that the telephone number is assigned.
Executive Summary:
The highlighted conclusion that includes that basis for why the research was performed, the results that concluded from the research and where they will take the company, and what moves the management should make to best react to the research findings.
Exhibit:
Anything that is on display during a qualitative discussion with respondents. Examples could include posters, advertisements, category lists, or television clips. Exhibits are also referred to as external stimuli.
Expected Value:
A probability distribution’s mean value. It represents that value that the sample is expected to take in the long run.
Experiencing Focus Groups:
Qualitative research that allows clients to observe and hear consumer’s thoughts and opinions regarding the client’s product or service.
Experiment:
A set of observations that are performed in an attempt to solve a question or problem.
Experimental Design:
A research design which allows the researcher to manipulate the independent variables and observe the reactions caused by such changes.
Experimental Effect:
The result that occurs to the dependent variable after the treatment variable has been altered.
Experimental Unit:
The smallest base object that is targeted during an experiment. Can also be referred to as a unit, subject, participant, respondent, or unit of analysis.
Exploratory Focus Groups:
Qualitative research that brings concepts to a group of people so that they can address customer needs, concepts for new products or evaluate existing products.
Exploratory Research:
The most basic level of research that is performed to clarify the exact problem at hand.
Exponential Smoothing:
Simply data recorded by time intervals.
Expressive Drawing:
A qualitative technique in which the moderator asks the participants to illustrate their feelings toward a particular product or service by creating a picture.
External Stimuli:
Physical objects that are presented in focus groups to so that the respondent’s reactions can be measured. Also called an exhibit.
External Validity:
The reality in which measured causal relationships in an experiment can be applied to uninvolved people, times and settings.
