Ma analysis isn’t easy to master, despite its many advantages. Inaccurate results can be obtained due to mistakes made during the process. To unlock the full potential of data-driven decision making, it is essential to identify and avoid making these mistakes. Most of these errors are caused by omissions or mistakes that can be easily rectified. Researchers can cut down on the number of errors they make by setting objectives that are clear and prioritizing accuracy over speed.
1. Failure to account for skewness
When conducting research One of the most frequent mistakes is to not take into consideration the skewness of a variable. This can lead to incorrect conclusions that may be devastating to your business. Double-checking your work is important particularly when dealing with complex data. It’s also an ideal idea to get a supervisor or a colleague to examine your work. They’ll be able identify any mistakes you could have missed.
2. Overestimating the variance
It’s easy to get carried away in your ma analysis and begin drawing false conclusions. But it’s important to remain scrupulous and question your own work – and not only at the end of a study when you’re no longer interested in that one particular data point.
Another mistake is to undervalue variance, or more importantly think that a set of data points has an equal distribution. This is a major error when looking at longitudinal data because it assumes that all participants experience the same effects at the same time. This is a mistake that can be avoided by examining your data and making sure to use the correct model.
