Answer» Ans. Quatitative data are anything that can be expressed as a number, or quantified. Examples of quantitative data are scores on achievement tests,number of hours of study, or weight of a subject. These data may berepresented by ordinal, interval or ratio scales and lend themselves to most statistical manipulation.Qualitative data cannot be expressed as a number. Data that represent nominal scales such as gender, socieo economic status, religious preference are usually considered to be qualitative data.Both types of data are valid types of measurement, and both are used in education journals. Only quantitative data can be analyzed statistically, and thus more rigorous assessments of the data are possible.
