Casio CFX9850GC Plus - DISCONTINUED BY MFG (SEE MODEL FX9860G
Offers List-Based, One-and Two-Variable Statistics - with the "PLUS", you can master list-based statistical calculations with both single and double variables. It also performs linear, median-median, quadratic, polynomial, cubic, logarithmic, exponential, power, logistic and sinusodial regressions.

SPECIFICATIONS:

• Standard calculations with both real and complex numbers
• Advanced functions available through on-screen, soft key menus
• Calculations performed with numbers or lists of numbers
