Cognitive Dissonance: The psychological conflict that sometimes arises after a major purchase decision (e.g., the purchase of a car or a house). It’s the anxiety or fear that one might have made the wrong choice, and it’s too late to undo the decision. To eliminate this conflict or dissonance, the buyer will often seek to rationalize his/her choice by searching for and remembering all of the positives about the choice and ignoring all of the disadvantages.
Cohort: A group of individuals having statistical similarities in a demographic study.
Cohort Measures: Analysis over an extended time period of the activity of a cohort, a group whose members experience an event within a particular time period.

Conditional Probability: A probability dependent on, or influenced by, other events or circumstances. The probability that a woman is pregnant, if aged 35 to 39, is an example of a conditional probability. That is, the probability is “conditioned” by the fact that the woman must be a certain age. Another example of conditional probability is, “What is the probability of drawing an ace from a deck of cards, when two cards have already been drawn (and neither card was an ace)?” The probability of drawing an ace is “conditioned” by the number of non-ace cards already drawn.
Confidence Intervals: The range around a survey percentage, plus or minus, that is likely to contain the population parameter (the correct answer).
Confidence Level: The probability that a given statistical range or interval will include the population parameter.
Confidentiality: Confidentiality is protecting study information, such as client name, brand name, purpose of the research, concepts, products, and research results, from unauthorized disclosure to any third party. Confidentiality also refers to protecting the privacy of and preventing the identification of any individual survey respondent.
Confirmation Email: To create its double-opt-in panels, Decision Analyst sends a confirmation email to prospective panelists who have registered to become members. Only after prospective members click on these confirmation emails do they become full-fledged members of Decision Analyst’s panels. In effect, prospective panelists have to register and then confirm by email that they really do want to become members.

Conjoint Analysis: A multivariate statistical technique that is used to measure the relative value of product attributes. The method involves rating or ranking subsets of attribute levels, evaluated jointly, such that it forces trade-off decisions based on judgments about the value of each attribute and level.

Consumer Unit: The Bureau of Labor Statistics defines a consumer unit as a consumer unit consists of any of the following: (1) all members of a particular household who are related by blood, marriage, adoption, or other legal arrangements; (2) a person living alone or sharing a household with others or living as a roomer in a private home or lodging house or in permanent living quarters in a hotel or motel, but who is financially independent; or (3) two or more persons living together who use their incomes to make joint expenditure decisions. The terms consumer unit, family, and household are often used interchangeably for convenience. However, the proper technical term for purposes of the Consumer Expenditure Survey is consumer unit.
Contact: Some type of communication with a potential respondent about participation in an upcoming survey.
Contact Rate: The percent of the total sample that was contacted (i.e., communicated with) for a survey.

Magic cookie, a term used in UNIX computing, is the source of the term “cookie.”
Co-Op Payment: The money or incentive given to respondents to encourage their participation in focus groups, depth interviews, mall-intercept interviews, or online surveys.

Cross-Classification Analysis: Analysis technique used with qualitative or categorical data, which classifies each respondent according to two or more mutually exclusive and exhaustive qualitative variables (such as region of residence and country of origin). Quantitative variables are sometimes used in classification analysis when transformed into categorical variables by consecutive values (such as annual income) into categories made up of ranges of values. The simplest cross-classifications are two way, but the technique can be generalized to deal with any number of dimensions.
Cross-Cultural Analysis: The collection and analysis of data that compares the findings from different countries (or cultures) together.
Cross-Elasticity: The cross elasticity of demand or cross price elasticity of demand measures the change in the number of units of one product demanded in response to a price change of a second product. The term can also be used more loosely to refer to the change in the demand for one product as the result of some change in another product. For example, the demand for new cars might go up as the price of gasoline goes down. Another example: the demand for rice might increase if the price of potatoes goes up.
