What is the primary challenge of a larger sample size?

The main thing happening with a larger sample size is the cost of collecting and handling more data. As you add more participants, you need more surveys or experiments, more personnel to manage the process, more data cleaning, and more storage and bandwidth. That financial and logistical burden tends to be the biggest hurdle in making a study bigger. Time to collect and analyze can rise as a consequence, and larger data sets do require more processing, but these are typically secondary to the upfront expenses. Properly designed larger samples can also improve precision, so data quality isn’t inherently worse with more data; it’s often better, provided sampling is done correctly.
