Small sample sizes can mislead standard error estimates
Imagine you're tasting a new ice cream flavor for the first time and only have one scoop to judge its quality.
With just one scoop, you can't tell if it's good or bad; you need more scoops to get a better sense of the flavor's true quality. This is like needing more data to accurately estimate the standard error.
Example
You taste one scoop and say it's good, but you don't know if it would be good or bad if you had more scoops to taste.
Remember this
Just like you need multiple scoops to judge the ice cream, you need more data to accurately estimate the standard error.
