Longitudinal Studies: A type of observational research in which the market researcher conducts surveys from a specific time period to another, i.e., over a considerable course of time, is called longitudinal survey.On the basis of the time involved in completing surveys, they are classified into the following – A critical factor about surveys is that the responses collected should be such that they can be generalized to the entire population without significant discrepancies. Surveys are integral in collecting feedback from an audience which is larger than the conventional size. The survey makes include answer options which they think are the most appropriate for a particular question. Closed-ended questions form a major part of these surveys as they are more effective in collecting quantitative data. Surveys: Traditionally, surveys were conducted using paper-based methods and have gradually evolved into online mediums. There are two main Quantitative Data Collection Methods: For example, asking respondents of an online survey to share the likelihood of recommendation on a scale of 0-10.Īs quantitative data is in the form of numbers, mathematical and statistical analysis of these numbers can lead to establishing some conclusive results. Quantification of qualitative entities: Identify numbers to qualitative information.For example, a marketer will predict an increase in sales after launching a new product with a thorough analysis. Projection of data: Future data projection can be made using algorithms and other mathematical analysis tools.For example, a digital camera converts electromagnetic information to a string of numerical data. Sensory calculation: Mechanism to naturally “sense” the measured parameters to create a constant source of information.For example, the HR executive carefully measures the size of each cubicle assigned to the newly joined employees. Measurement of physical objects: Calculating measurement of any physical thing.For example, the number of people downloading a particular application from the App Store. The most common types of quantitative data are as below:

Researches can establish the retrieved results across a population. It is usually collected for statistical analysis using surveys, polls, or questionnaires sent across to a specific section of a population. Quantitative data makes measuring various parameters controllable due to the ease of mathematical derivations they come with. Values are associated with most measuring parameters such as pounds or kilograms for weight, dollars for cost, etc. For instance, “How much did that laptop cost?” is a question that will collect quantitative data. This data can be verified and conveniently evaluated using mathematical techniques.įor example, there are quantities corresponding to various parameters. Quantitative data answer questions such as “How many?”, “How often?”, “How much?”. This data is any quantifiable information that researchers can use for mathematical calculations and statistical analysis to make real-life decisions based on these mathematical derivations.

Quantitative data is the value of data in the form of counts or numbers where each data set has a unique numerical value.
