Write a 250-to 300-word analysis of your preferred strategies for establishing validity and reliability for a quantitative data collection instrument you may design. Defend your choice of each state   Validity & Reliability for a Quantitative Study Analyze various types of validity strategies for quantitative studies. Analyze various types of reliability strategies for quantitative studie There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research. attempts to establish cause- effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences. There are three main types of research design: Data collection, measurement, and analysis. The type of research problem an organization is facing will determine the research design and not vice-versa. The design phase of a study determines which tools to use and how they are used. How do you establish reliability in qualitative research? The consistency of data will be achieved when the steps of the research are verified through examination of such items as raw data, data reduction products, and process notes (Campbell, 1996). To ensure reliability in qualitative research, examination o What is Reliability vs validity? Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability). Validity is the extent to which the scores actually represent the variable they are intended to. Validity is a judgment based on various types of evidence.   What is an example of reliability and validity? For a test to be reliable, it also needs to be valid. For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs. The scale is reliable because it consistently reports the same weight every day, but it is not valid because it adds 5lbs to your true weight. Does reliability affect validity? Validity will tell you how good a test is for a particular situation; reliability will tell you how trustworthy a score on that test will be. You cannot draw valid conclusions from a test score unless you are sure that the test is reliable. Even when a test is reliable, it may not be valid What is validity and reliability in quantitative research? Validity is defined as the extent to which a concept is accurately measured in a quantitative study. ... The second measure of quality in a quantitative study is reliability, or the accuracy of an instrument.
