Question

How might we, as epidemiologists, increase the validity of genetic studies? What recommendations do you have (assume that you have all of the resources you'd need to implement these changes)?

Answer 1

There are number of ways to increase the validity of genetic studies. Some of these are as follows:-

• Controlling more variables is about making sure as few things as possible change during the experiment. An ideal experiment is where one thing is changed and one result is looked at, everything else should remain same. The more you keep the same, the more likely it is that your result will be valid.
• Improve the measurement techniques:- Improvement in measurement techniques should also be helpful in increase the validity of the genetic disease. Instead of doing the calculations and other measurements by hand, use some computer based softwares for the accurate results.
• Increasing Randomization:- Increase randomization in sample helps to reduce the sampling bias. Use random numbers or the groups in population to reduce the kind of bias in results and to increase the validity od study.
• Adding control group in a study:- There should be one control group in a study, that doesn,t include the things being tested and is to measure the results of the other group, in any valid experiment. This group also helps in making study comparison between both groups.
