Is your taxable scholarship income less than $6300? If so, it is the interest that is lowering it because you are a dependent.
For dependents, $6300 is the Standard Deduction for earned income (from a job, but for this purpose only, taxable scholarships also count as earned income).
Standard Deduction for unearned income (such as interest) is $1050.
If you have a combination of both, it is $350 plus your earned income (up to a $6300).
