Validating quantitative data model

An instrument is content valid when the items adequately reflect the process and content dimensions of the objectives of the instrument (Benson & Clark, 1982).Again, the instrument should be distributed to a sample that is representative of the target group.Each phase consists of several steps that must be taken to fully satisfy the requirements for fulfilling a phase.During these sessions, students can ask questions about research design, population and sampling, instrumentation, data collection, operationalizing variables, building research questions, planning data analysis, calculating sample size, study limitations, and validity.By continuing to use this site, you consent to the use of cookies.

In this step, the researcher should identify the purpose of the test, specify the content area to be studied, and identify the target group.

If it is determined that there are no instruments available that measure the variables in a study, there are four rigorous phases for developing an instrument that accurately measures the variables of interest (Creswell, 2005).

Those four phases are: planning, construction, quantitative evaluation, and validation.
