# Top 7 Factors for Good Experimental Practice

By [Astrid Haegens, PhD](https://blog.transonic.com/life-science-research/author/astrid-haegens-phd)05 Mar 2021

*“The validity of an experiment is directly related to the attention paid to and time spent on preparation prior to the experiment.” *

A bold statement, but from my years of working with both more and less experienced scientists in addition of my own years in the lab, I have learned that doing your homework pays off. This is why today I’m going suggest several points to consider when designing your experiments. Some are more obvious than others; several are relatively easy to implement, and they all contribute to the quality of your research. This is by no means a complete list or in order of importance, but I hope that this blog will prompt you to think once or twice that ‘I didn’t think of that before’ and you will give it consideration when preparing your next project.

** **

1. **Choose quality of data over quantity of data**. Animal lives are precious and you should always aim not to waste any tissue or omit to collect relevant data that is available. However, there should be a balance between collecting all that you can and collecting the best way possible. Each technique and type of data comes with their own requirements. Some can be combined in one experiment, and some are just not reconcilable. Be critical! What is a ‘must have’ to answer the hypothesis and which data or tissue is ‘nice to collect’. This may mean that you have to use separate animals for separate end-points. This is not ideal, but it is always better to be able to collect meaningful data, than to take a short cut and have inconclusive results.    

It is always a good idea to reflect occasionally on the routines in the lab. Some of the above suggestions might seem redundant, and you can check them off the list easily. Great! However, if you catch yourself thinking, ‘I do this because this is how my colleague does things’, you may want to give it a second thought. The right way that works for your colleague does not automatically mean it is the preferred way for you and your experiments. We all know the ‘this is how it always has been done’. If we would stick to that premise, typewriters would still be in fashion and we would type papers by candle light. At Transonic we have a team with more than three decades of lab experience, in addition we work with and learn from all our customers. Sometimes an outsider has a fresh view on how routines have become routines, and a different set of eyes may give you the opportunity to create new and better routines.
