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) *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
