The right bias synonym depends on how unfair the tilt is. Leaning and preference are gentle, partiality and favoritism say someone is being unfair, and prejudice points to a fixed negative view of a group.
Bias also has a technical sense in research, where it means a built-in error that pushes results one way. In that sense, skew and distortion fit better than any word about personal attitudes. This page sorts every option by meaning and strength, then covers the adjective biased.

How strong is each word
Read the strip at the top from left to right. A leaning is a light pull. A preference is a choice you are aware of. Partiality means the preference affects your judgment. Prejudice means a judgment formed before the facts, often about people. Bigotry is the harshest, describing deep and open hostility.
In a fair, balanced essay, start low on the scale and move up only when your evidence supports it.
Synonyms for biased
For the adjective, try prejudiced, partial, one-sided, slanted, skewed or partisan. Partisan fits politics and team loyalty. Slanted and one-sided suit articles and coverage. Skewed is best for data. Unfair is the plain everyday choice; see unfair synonyms.
Be careful with partial: it can also mean incomplete, so a partial review may confuse readers.

Common mix ups
Opinion is not bias. Everyone has opinions; bias is when a view bends how you treat evidence or people. Discrimination is unfair treatment, the act that can follow from prejudice. Stereotype is a fixed idea about a group, a cause of bias rather than a synonym. Keep these apart in essays on social topics and your argument will be cleaner. For neutral words, see opinion synonyms.
