Quadratic Regression type Statistical Calculation Example:

ABC Company investigate the effectiveness of the advertisement expense in

coded units, the following data were obtained:

Advertisement expenses: X

Effectiveness: y (%)

Please use the regression to estimate the effectiveness (estimate the value of y)

if the advertisement expenses X=30, and estimate the advertisement expenses level

(estimate the value of 

Function (X, Y) Table Calculation

 Input f(x) function to generate the function table for x & f(x),

 Steps to generate a Number Table

1. Enter TABLE Mode

· Press MODE 3 to enter the Table function calculation,

2. Function Input screen

· Input function with X variable ( Alpha x ) to generate Function Table

Result.

· All other variables (A,B,C,D, E, F, Y) and independent memory (M) act

as the value.

· Pol, Rec, I-Div function not able to be used in Function Input screen.

· The Function Table Calculation will change X-variable.

3. Input the start, end & step information

· Input the value press = to confirm on the following screens

· Input expression and display result value in following screens are in

Line mode status

· There are a maximum of 30 x-values for generate function table, The

n if you input the start, end, step value combination is

more than 30 x-values.
