The Type of Variable

a. Independent variable: variable influence

or have effect on dependent variable

b. Dependent variable: variable influenced

or give response to independent variable

c. Antecendent variable: variable influence

on independent variable

d. Random variable: variable does not

influence on dependent variable

(3)

The Kind Of Variable

f. Suppressor /nuisance/extraneous/variable: variable

besides on independent variable which influence

on dependent variable

This variable must be controlled become random

variable/control variable

In the research method, these variables must be

described explicitly on procedure

g. Substitute variable/observation: replacer

variable/observation of dependent variable if the

dependent variable is difficult to be observed

h. Covariate variable/concomitant

THE INFLUENCE OF PHOSPHATE FERTILIZER CONSENTRATION ON THE PRODUCTIVITY OF CORN SEED

i. IND VAR : PHOSPHATE FERTILIZER CONSENTRATION  AS FACTOR

DECLARE THE NUMBER OF FACTOR LEVEL  3 LEVEL IN LABORATORY EXPERIMENT: 0 G/POLYBAG, 2 G/POLYBAG, 4 G/POLYBAG , OR

4 LEVEL IN FIEPD EXPERIMENT: 0 KG/HA, 10 KG/HA, 20 KG/HA, 30 KG/HA

II. DEP VAR (AS PRIMERY OBSERVATION ): PRODUCTIVITY OF CORN SEED CAN BE MEASURED (WITHOUT SUBSTITUTE

OBSERVATION/PARAMETER)

III. SUPPRESSOR VAR : A. FROM OBJECT

1. VARIETY OF CORN  MENTION THE VARIETY OF CORN IN THE RISEARCH TITTLE

2. VIABILITY OF CORN SEED  DECLARE THE VIABILITY OF CORN SEED IF THE EXPERIMENT STARTED BY PLANTING THE SEED (OR DECLARE THE SEEDLING SIZE  THE HEIGHT OF SEEDING IF EXPERIMENT

(5)

B. MEDIA

1. MEDIA DETERMINED BY LOCATION  DECLARE LOCATION OF

EXPERIMENT (WONOSARI  LIME SOIL , , PONTIANAK  PEAT SOIL)

2. LABORATORY EXPERIMENT a) MEDIA

1) SOIL TYPES  DECLARE THE SOIL TYPE IN THE RESEARCH PROCEDUR

2) ADDITIONAL DROPSY FERTILIZER  DECLARE THE ADDITIONAL DROPSY FERTILIZER ON THE SOIL

3) THE SOIL HOMOGENITY  DECLARE THE SOIL WAS MIXED IN ORDER TO HOMOGEN

4) POLYBAG SIZE  DECLARE THE VOLUME OR DIAMETER OF POLY BACK

5) THE SOIL VOLUME  DECLARE THE SOIL VOLUME IN EACH POLYBACK

6) DAILY ADDITIONAL WATER  DECLARE ADD WATER UNTIL THE SOIL BECOME SATURATED.

C. CLIMATIC FACTOR

1. FILED EXPERIMENT

DETERMINED BY MONTH OF EXPERIMENT IS IMPLEMENTED) 2. LABORATORY EXPERIMENT

(6)

D. MEDIATOR VAR

a) AS EXPLANATORY VAR (IF DATA WERE

COLLECTED)  DRY WEIGHT OF ROOT, STEM

AND LEAFS

b) AS INTERVENING VAR (IF DATA WERE NOT

COLLECTED  TO DESCIBE ON THE LITERATURE

SUTDY)  THE CON SENTRATION OF PHOSPHATE

ON THE SOIL AFTER FERTILIZATION, INTENSITY

OF ROOT ABSORBSION, INTENSITY OF

METABOLISM PROCESSES, LOCATION OF

DEPOSITION OR ACCUMULATION THE

METABOLISM RESULT

D. RANDOM VARIABLE  EXAMPLE: SEX OF
