A sample size of 300 people.

Explanation:

The answer is "a sample size of 300 people".

Usually, the sample size has a significant impact on the accuracy of any study. If The sample size is larger, the result will be better. It is said here that the sample size was only 300 people. Marcus is necessarily indicating that he has a limited window of insight. It means it's showing the limitation of the study. If the sample size were larger than 300, the result would be more accurate.

For this reason, Marcus wants to repeat his research with larger sample size.
