This means unforeseen circumstances can interfere with your results regardless of how much data you collect.

If you’re mostly dealing with quantitative data, spotting patterns is relatively simple and you can charts and similar visualizations to help you out. Instead of logging into multiple tools, you can connect your data source (100+ integrations available) and drag all of your key findings into one comprehensive dashboard. It depends on what you’ve defined as your goal, what type of data you’re dealing with, which resources are available to you, etc. While cleaning data is generally considered the most “tedious” part of the process, it’s a necessary step in making sure your analysis yields the most useful insights and information. As for external resources, a good idea can be to check out specific industry reports, government data, and market research studies.
