How do you write validity and reliability?
A valid measurement is generally reliable: if a test produces accurate results, they should be reproducible….Where to write about reliability and validity in a thesis.

What is validity and reliability in research examples?
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.
What is validity 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.
What is external validity concerned with?
External validity is the validity of applying the conclusions of a scientific study outside the context of that study. In other words, it is the extent to which the results of a study can be generalized to and across other situations, people, stimuli, and times.
How do you establish external validity?
External validity is addressed by delineating inclusion and exclusion criteria, describing subjects in terms of relevant variables, and assessing generalizability.
Is external validity the same as generalizability?
Generalizability refers to the extent to which the results of a study apply to individuals and circumstances beyond those studied. (1) Com- monly referred to as external validity, generalizability is the degree to which a given study’s findings can be extrapolated to another population.
What does it mean that reliability is necessary but not sufficient for validity?
Reliability is necessary but not sufficient for validity. If you used a normal, non-broken set of scales to measure your height it would give you the same score, and so be reliable (assuming your weight doesn’t fluctuate), but still wouldn’t be valid.
How can validity be improved in quantitative research?
When you design your questions carefully and ensure your samples are representative, you can improve the validity of your research methods.
- Ask Specific and Objective Questions.
- Make the Sample Match the Target.
- Avoid Self-selection.
- Use Screening to Make Your Sample Representative.
