These methodologies define different types of research and are concerned with the overall strategy the researcher chooses (Leedy & Ormrod 2005:86). Philosophies means approaches e.g. •OTHER TYPES External Validity: It is the extent to which the results of a research study can be generalized to different situations, different groups of people, different settings, different conditions, etc. Quantitative Research Trying to quantify variables of interest; questions must be measureable Key characteristic: data involves numbers Questions frequently address “how well or how much” Example: What is the relationship between graduate students’ level of interaction, measured by the number of ‘hits’ in the course, and students’ grades in an online research Types of validity in research. are often based on the lack of predictive validity of these tests). Validity in Research 9 achieved in the classroom. •All items are relevant to all types of criteria. The questions on the scale should have a logical reason why they … Face validity is not an authentic way to check the validity of the research. The validity of the results may therefore be questioned, and it The personality types and their correlations as the findings of the research are pictured in Figure1 (Holland, Whitney, Cole, & Richards, 1969).

Face validity measures the validity of the instrument by creating a logical relationship between the questions on the scale and the objectives of the study. If the results are accurate according to the researcher's situation, explanation, and prediction, then the research is valid. Content Validity •The items in the questionnaire truly measure the intended purpose. Predictive Validity refers to the extent to which the results and conclusions can be used to predict real life applications of the study. Research reliability can be divided into three … Alternative Forms 1.1. Types … External Validity-extent to which the study relates to the population -concerned with comparability and translatability . • Explain various research design techniques to protect internal validity. Types of Validity 4 External validity The extent to which the results of the study can be statistically generalized beyond the context of the original study.

In summary: Construct: Constructs accurately represent reality.. Convergent: … Other types of validity that you can consider when developing a test are construct validity, content validity, face validity, and criterion validity.

When using the alternative form method of testing the relaiability of an assessment, there are two forms of one test. Th e authors presume that validity is an essential component of research and has a signifi cant impact on the reliability of research … In particular sample size and validity are the most often queried aspects of qualitative research.
