To provide the monthly difference in median income for a female with a high school diploma and some college versus a bachelor's degree, I would typically need specific income data. However, in general, the income for these educational levels is often reported in earnings statistics.
As of my last knowledge update, females with a high school diploma might earn around $3,000 per month, whereas those with a bachelor's degree might earn around $4,500 per month.
So, if we were to fill in the blanks with those hypothetical figures:
Monthly difference = $4,500 - $3,000 = $1,500
Thus, the answer would be: $1,500.00
Please check the latest statistics for accurate figures, as these can vary.
