# Statistics on the Calculator for NSW Secondary Mathematics Students

Below are the step by step instructions of how to use a scientific calculator for statistics in high school mathematics. Statistics Mode

• MODE

• STAT (2) 1-VAR (1) A+BX (2) Single Set of Data Bivariate Data X X Y

Frequency This can be used for both the Single Set Data (1-VAR) or the Bivariate Data (A+BX)

• SETUP (SHIFT MODE)

• STAT (3)

• Frequency (1) ON (2) OFF

Single Set Data

• MODE

• STAT (2)

• 1-VAR (1)

• Enter Data (=)

• Clear Screen (AC)

• STAT (SHIFT 1)

o Data (2) Displays Data

o Var (4) - Variables (1) n = number of scores (2) = mean (3) σx = population standard deviation (4) sx = sample standard deviation

o MinMax (5) 5 Number Summary (used for Box-and-Whisker Plots) (1) minX = smallest score (2) maxX = largest score (3) Q1 = lower quartile (4) med = median (5) Q3 = upper quartile

Bivariate Data

• MODE

• STAT (2)

• A+BX (2)

• Enter Data (=)

• Clear Screen (AC)

• STAT (SHIFT 1)

o Data (2) Displays Data

o Var (4) - Variables (1) n = number of scores (2) = mean of x scores (3) σx = population standard deviation of x scores (4) sx = sample standard deviation of x scores (5) ȳ = mean of y scores (6) σy = population standard deviation of y scores (7) sy = sample standard deviation of y scores

o Reg (5) - Regression (1) A (2) B The above gives the equation of the regression line, y=A+Bx (3) r = correlation coefficient

o MinMax (6)

(1) minX = smallest x score

(2) maxX = largest x score

(3) minY = smallest y score

(4) maxY = largest y score
