How do you tell the difference between male and female bass fish?

Generally, it can only be told by inspecting the anal opening during mating season. Also, the males, when nesting, tend to turn slightly more pale and may have red eyes. Females may be bulging with eggs.

Females grow larger than males. The largest male is known to be about 8 pounds, where females can be larger than 22 pounds.

Your question has one big problem! There are three dozen different fresh and salt water "bass" species [The Temperate Bass Family] common in and around North America. Some are dimorphic and others can only be sexed by behavior or genetial during spawning. Both sexes can assume different general sizes depending on the time of year.
