quantitative

Examples of quantitative in the following topics:

• Research Methods for Evaluating Treatment Efficacy

  • When assessing the effectiveness of therapy, researchers often rely on mixed-method designs, which means using both quantitative and qualitative designs.
  • Unfortunately, a number of theoretical models used in therapy, such as interviews and observations, lack quantitative data to support their effectiveness and rely solely on qualitative data.
  • Ideally, therapies should use mixed methods to provide both quantitative and qualitative data.
  • One way of gathering quantitative data is through the use of inventories.
  • Qualitative data can provide subjective information that cannot be measured or effectively captured by quantitative methods.

• Observation

  • Unlike correlational and experimental research which use quantitative data, observational studies tend to use qualitative data.
  • While observational studies can generate rich qualitative data, they do not produce quantitative data, and thus mathematical analysis is limited.

• Surveys and Interviews

  • Surveys may measure either qualitative or quantitative data.
  • Quantitative data are always numbers.
  • Quantitative data are the result of counting or measuring attributes of a population, such as money, pulse rate, weight, or populations.

• Case Studies

  • Case studies also tend to use qualitative data, such as interviews, but may occasionally use quantitative data as well, like questionnaires.

• Standardized Tests

  • Aptitude tests, which, like achievement tests, measure what students have learned; however rather than focusing on specific subject matter learned in school, the test items focus on verbal, quantitative, problem solving abilities that are learned in school or in the general culture.

• Descriptive and Correlational Statistics

  • Tools used for descriptive statistics include quantitative measures such as the mean, median, and mode, as well as a distribution curve.

• Cognitive Development in Childhood

  • Seriation is the ability to order items by a quantitative dimension, such as height or weight.

• Cognitive Development in Adolescence

  • The constructivist perspective, based on the work of Piaget, takes a quantitative, state-theory approach.
