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 Brivariate 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) x̄ = 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) x̄ = 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
