Researching Target Markets
International Market Research
Week 4 - Introduction
Market research is any organized effort to gather information about target markets or customers. It is a very important component of business strategy. The term is commonly interchanged with marketing research; however, expert practitioners may wish to draw a distinction, in that marketing research is concerned specifically about marketing processes, while market research is concerned specifically with markets. ( Wikipedia )
Marketing research [...] is the systematic gathering, recording, and analysis of qualitative and quantitative data about issues relating to marketing products and services. ( Wikipedia )

In sociology, quantitative research refers to the systematic empirical investigation of social phenomena via statistical, mathematical or numerical data or computational techniques. ( Wikipedia )
Qualitative research is a method of inquiry employed in many different academic disciplines, traditionally in the social sciences, but also in market research and further contexts. Qualitative researchers aim to gather an in-depth understanding of human behavior and the reasons that govern such behavior. The qualitative method investigates the why and how of decision making, not just what, where, when. Hence, smaller but focused samples are more often used than large samples. ( Wikipedia )
Week 6
A field of applied statistics, survey methodology studies the sampling of individual units from a population and the associated survey data collection techniques, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys. ( Wikipedia )
Week 7
A survey involves interviews with a large number of respondents using a predesigned questionnaire ( Teacher )
A questionnaire is a research instrument consisting of a series of questions and other prompts for the purpose of gathering information from respondents. Although they are often designed for statistical analysis of the responses, this is not always the case. ( Wikipedia )
Questionnaire construction regards questionnaires. It is a series of questions asked to individuals to obtain statistically useful information about a given topic. ( Wikipedia )
Quantitative marketing research is the application of quantitative research techniques to the field of marketing. It has roots in both the positivist view of the world, and the modern marketing viewpoint that marketing is an interactive process in which both the buyer and seller reach a satisfying agreement on the "four Ps" of marketing: Product, Price, Place (location) and Promotion. ( Wikipedia )
Week 9
Statistical Methods
Statistics is the study of the collection, organization, analysis, interpretation and presentation of data. It deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments ( Wikipedia )
Calculus is the mathematical study of change in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations.
- It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integral calculus (concerning accumulation of quantities and the areas under curves); these two branches are related to each other by the fundamental theorem of calculus. ( Wikipedia )
A time series is a sequence of data points, measured typically at successive points in time spaced at uniform time intervals. ( Wikipedia ) An example are the closing values over time of stock market index ( jubo-jubo )
Week 4 - Introduction
- Population
- Census
- Unit (sampling unit)
- Sample and Sampling
- Variable
- Data matrix
- One row for one unit
- One column for each variable
There are different levels of measurement
- The mode is the value that appears most often in a set of data. ( Wikipedia )
Week 6
In statistics and probability theory, the median is the numerical value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. ( Wikipedia )
In descriptive statistics, the quartiles of a ranked set of data values are the three points that divide the data set into four equal groups, each group comprising a quarter of the data. ( Wikipedia )
In arithmetic, the range of a set of data is the difference between the largest and smallest values. ( Wikipedia )
A Likert scale is a psychometric scale commonly involved in research that employs questionnaires. It is the most widely used approach to scaling responses in survey research, such that the term is often used interchangeably with rating scale, or more accurately the Likert-type scale, even though the two are not synonymous. The scale is named after its inventor, psychologist Rensis Likert. ( Wikipedia )
In statistics and w:probability theory, the standard deviation (represented by the Greek letter sigma, σ) shows how much variation or dispersion from the average exists. ( Wikipedia )

- In descriptive statistics, the quartiles of a ranked set of data values are the three points that divide the data set into four equal groups, each group comprising a quarter of the data. A quartile is a type of quantile.
- w:Quantiles are points taken at regular intervals from the cumulative distribution function (CDF) of a random variable.
A percentile (or a centile) is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall. ( Wikipedia )
- In statistics and probability theory, the standard deviation (SD) (represented by the Greek letter sigma, σ) shows how much variation or dispersion from the average exists.
- A low standard deviation indicates that the data points tend to be very close to the mean (also called expected value); a high standard deviation indicates that the data points are spread out over a large range of values. ( Wikipedia )
- The coefficient of variation (CV) is a normalized measure of dispersion of a probability distribution or frequency distribution. ( Wikipedia )
- A w:histogram is a graphical representation of the distribution of data. It is an estimate of the probability distribution of a continuous variable and was first introduced by Karl Pearson. ( Wikipedia )
