The phrase "a relatively wide sample" is correct and usable in written English.
It can be used when discussing research, surveys, or studies to indicate that the sample size is larger than average or encompasses a diverse range of subjects.
Example: "The study was conducted using a relatively wide sample of participants from different age groups and backgrounds."
Alternatives: "a fairly large sample" or "a comparatively broad sample".
