Is 100 respondents enough for quantitative research?
In most cases, we recommend 40 participants for quantitative studies. If you don't really care about the reasoning behind that number, you can stop reading here. Read on if you do want to know where that number comes from, when to use a different number, and why you may have seen different recommendations.
What is a good sample size for user research?
“For usability studies aim for around fifteen users to get enough data points (30 is ideal)” – suggested by Rubin, Chisnell & Jared Spool. More participants often lead to better data. Including more people who are representative of your target users is always a good idea.
How many people do you need for user research?
Generally speaking, you'll want to conduct a minimum of 5-6 user interviews to identify and validate key user needs and design requirements.
How many participants do you need for a UX survey?
Minimum Sample Size
Realistically, it's essential to aim for 100, scalable up to 300 people, for a reasonably good sample size. I understand these numbers might sound very high at the moment, but these numbers fundamentally represent the entire targeted audience, ranging from 10,000 to a size of a nation.
