The Power of Pilot Studies: Why testing your instruments first can save you months of “bad data” later

Research

It would be like spending six months of your time gathering data of five hundred people only to discover during the analysis of your results that your main question in the survey was misunderstood by forty percent of the people. The result? The null result is not really an outcome at all, it is noise.

The Go Big or Go Home mentality is a disaster in the world of empirical research. The key to high-impact research however is not the large sample size but rather the pilot study. You insure your project against the disastrous price of bad data by testing your instruments beforehand.

What is a Pilot Study?

A pilot study is a miniature, preliminary research of your research work. It acts as a dress rehearsal to your methodology. Whether it is the new psychometric scale, structured interview protocol, or a complicated laboratory sensor, the pilot study can help you locate the bugs in your system before you invest your entire budget and schedule.

Determining Research Instrument Ambiguity

The most experienced researchers may fall into the pit of expertise blindness. You could create a questionnaire that would make perfect sense to you but the target demographic may be confused.

Cognitive debriefing can be used during a pilot study. It entails posing a question to a few respondents requiring them to provide an explanation of their understanding of a question as they responded to it. In case they do not understand as you would like them to, you can tailor your words. This is the point at which Scientific and Technical Editing comes in very handy. The work of professional editors guarantees the linguistic accuracy, cultural sensitivity as well as logical integrity of your instruments to avoid data skewing due to mere misunderstandings.

Finding out the Logistics of Data Collection

Research does not take place in a vacuum, it is a real world. A pilot study is a test of the plumbing of your study:

  • Time Limits: Is it really the case that 10 minutes, or is it 30? When the participants are fatigued, the result is that they are straight-line (giving the same answer to all questions) thus compromising data quality.
  • Technical Glitches: Does mobile data collection software crash on your data collecting software? Are the digital files saved in a format to be analyzed by your analysis software?
  • Recruitment Feasibility: Is your inclusion too strict? A pilot study will give you an insight into whether you can eventually find the subjects you are seeking.

Enriching Statistical Power

A pilot study gives you a preview of the difference between your data. A power analysis can be more accurately done by analyzing the preliminary results of a small group. This can be used to calculate the number of subjects required to complete the study to be statistically significant. Otherwise, you can complete your primary research only to find out that you are underpowered, that is, your sample was so small that it was unable to show your hypothesis is even true.

Professional editing of Your Protocol

Research

Once the pilot study unveils the areas of the friction, you have to revamp your documentation. This is where most researchers fail. They do the adjustment internally but do not update their formal protocols to create discrepancies.

The Scientific and Technical Editing at the post-pilot level will guarantee that your new approach is written in a clear manner to your research team and other future peer reviewers. Technical manuals and standard operating procedures (SOPs) should be clear in order to lessen human error in the high-pressure stage of full-scale data collection.

Financial and Emotional Cost of Skipping the Pilot

It is also easy to be tempted by the pressure to submit within the set time so that researchers may bypass the pilot stage. This is however a fake economy. Two weeks of pilot study will not be expensive compared to the cost of losing six months of corrupted data.

Bad data is not only a statistical nightmare, but a danger to your career. Nowadays journals require more transparency as concerns instrument validation. In case you are not able to demonstrate that your instruments were tested and verified, the reviewers might doubt the quality of your whole dataset.

The conclusion is: Pilot First, Publish Faster

Preparation is the foundation of the way to successful publication. A pilot test serves as your insurance policy for the research. It explains your goals, justifies your instruments, and simplifies your business process. That is, where you bring together an intense pilot study and the accuracy of the Scientific and Technical Editing, you are no longer in the sphere of hoping to get results but making a difference.
