When it comes to research studies, analyzing data is key to unlocking valuable insights. But not everyone is a stats expert, right? So what should/can you do? If your research involves data, you should call in a Statistician, who can help ensure your results are accurate and reliable.
The question is, when should you bring a Statistician on board? The short answer is, the sooner the better. Let’s look at the different stages of a study and see how a statistician can help at each one.
Study Design
If you’re planning your research, it’s a smart move to get a statistician involved from the get-go. For starters, they can help you design the study and figure out the best way to collect data. And that can make a huge difference in the quality of your results. Plus, by getting a statistician involved early on, you can make sure that the data you’re collecting is actually going to be useful for the statistical analysis you want to do later.
Ideally, one should consult with a statistician even before you begin the data collection process begins. They can help you with all kinds of crucial decisions such as determining the optimal size of your research sample and selecting the most appropriate statistical methods. More importantly, they can help you with power analysis. which is a method to prevent you from collecting too little or too much data, something that can both affect the accuracy of the results and waste valuable resources.
One of the most important things a statistician can help you with is identifying potential confounders that may need to be accounted for in the study design. Confounders are variables that may influence the relationship between the independent and dependent variables you are studying but are not themselves the focus of the study. For example, if you’re trying to see if nutrition affects academic performance in kids, your statistician might tell you to control for things like the kids’ socioeconomic status. Failing to account for such confounding variables can lead to inaccurate or misleading results.
Data Collection
Even if a study is already underway, it is never too late to consult a statistician. In fact, bringing in a statistician during the data collection phase can help you improve the quality of the data being collected. They can review you your data collection methods, pinpoint any biases that may have crept in and recommend methods to minimize such biases. This can help ensure that the data collected is of high quality and is suited to the statistical analyses you have planned.
Data Analysis
Some researchers wait until the data has already been collected to consult with a statistician. While this is not ideal, it is still better than not consulting with a statistician at all. In these cases, statisticians can still review and identify any potential problems with your data, recommend appropriate statistical methods to analyze it. For example, a statistician can help you figure out if the data you’ve collected is normally distributed or not. And if it’s not, they can advise you on whether to use log-normal transformation or non-parametric tests instead.
Manuscript Preparation and Publication
And the story doesn’t end here. A statistician can help you in reporting the statistical data in your research paper, including relevant tables and figures. They can also assist you in creating relevant tables and figures and give you guidance on how to discuss the implications of your statistical findings. Plus, they can make sure that your statistical reporting meets your target journal’s requirements.
Even after you submit your paper and receive peer-review comments, a statistician can still come in handy. Sometimes reviewers have questions or concerns about the statistical analysis in a manuscript. In such cases, a statistician can help you address those comments and provide additional explanations or analyses if needed. This can really improve the quality of your paper and increase the chances of it being accepted.
Conclusion
To sum it up, it’s a good idea to bring a statistician onto your research team as early as possible, ideally during the planning stage. But even if you’ve already started your study or collected data, a statistician can still be super helpful. They can provide valuable input on how to analyze and present your data in a way that increases your chances of getting published.
Consulting a statistician can improve the quality of your research and the evidence it provides, which ultimately enhances your credibility and reputation as a researcher.
