That's an odd way to phrase it, since it doesn't seem like a particularly large sample as you state it. So how many individuals are you talking about, given your turnover?
Back up here. OC said "we run a small business and print checks manually". OC also said "With our employees being typically over 40, it's been rare to even have someone request direct deposit." So I responded from my own experience running payroll at what was also a small business, with employees who were also all 40+ years old. Where the heck does sample size come into this? It’s completely beside the point. We’re sharing anecdotes here, not research projects.
