Depending on factors such as your requirement, budget, timeline you can choose the best research type for your project.
Primary and secondary data both have their own advantages and disadvantages.
In primary data, as the research is done by the researcher himself, it’s more authentic and accurate. But at the same time it is expensive and time-consuming.
In Secondary research, the data collection is quick and comparatively cheaper than primary research. However, the data may be outdated and may not suit your requirement.
So, I would prefer to choose the kind of research based on my project.
