STAT

[FX-870P/VX-4]

Purpose

Enter statistical data.

Format

STAT X_data [, Y_data] [; Frequency]

Example

STAT 1, 3; 10
STAT 5.2
STAT 2, 7

Parameters

1. X_data: Numeric expression for the X data value.
2. Y_data: Numeric expression for the Y data value (optional, for paired data).
3. Frequency: Numeric expression specifying how many times this data point is entered (optional, default is 1).

Explanation

1. Enters data for statistical processing.
2. When only X_data is specified, single-variable statistics are performed.
3. When both X_data and Y_data are specified, paired-variable statistics are performed (required for correlation and regression functions).
4. The frequency parameter after the semicolon allows entering the same data point multiple times. For example, STAT 1, 3; 10 enters the data point (1, 3) ten times.
5. Use STAT CLEAR to initialize the statistical data before entering new data.

Sample Program

10 STAT CLEAR
20 FOR I = 1 TO 5
30 READ X, Y
40 STAT X, Y
50 NEXT I
60 DATA 1,2,3,4,5,6,7,8,9,10
70 PRINT "MEAN X="; MEANX
80 PRINT "MEAN Y="; MEANY

Enters five paired data points and displays the means.
